Garmin Forerunner 50 - Fitness Watch

Chuck — Mon, 27 Aug 2007 17:29:00 -0400

In October, Garmin will be releasing a new fitness device, the Forerunner 50, which is not GPS-enabled. According to a Garmin press release, the Forerunner 50 is…

“an affordable, sleek and intelligent way to help runners and walkers track their workouts, automatically store their data and reach their personal fitness goals.”

“The central element of the Forerunner 50 system is an advanced fitness watch which interfaces wirelessly with other fitness devices such as a heart rate monitor or a foot pod that monitors speed and distance. The system includes a wireless USB ANT™ Stick that plugs into the user’s PC and automatically downloads workout data stored on the watch to a personal computer. No cables are necessary as the Forerunner 50 synchronizes with the computer once it is in close proximity. Depending on the model purchased, the Forerunner 50 accurately monitors and records heart rate or speed and distance or all of the above. The workouts themselves are made easier with the Forerunner 50 as its heart rate monitor and foot pod activate automatically upon movement, removing the need to turn the lightweight accessories on and off.”

“When used with Garmin Connect™ — Garmin’s online training site — the Forerunner’s benefits continue long after the workout. By pairing the Forerunner 50 with Garmin Connect, users can automatically log their workouts, track their totals, share workouts with coaches, friends and family and participate in an online fitness community with similar interests.”

With no GPS, the Forerunner 50 is a big departure from the Forerunner series. It appears that Garmin is targeting the fitness/running/HRM watch audience, particularly users of the Polar S120 and Polar RS200sd. I’m a little perplexed on why Garmin has decided to produce a non GPS-enabled fitness device. My preference would have been a GPS-enabled Forerunner with the size of the Forerunner 50.

Currently, I own a Polar RS200sd running HRM with foot pod for speed and distance. I’m also a very happy owner of a Garmin Forerunner 305 and an Edge 305, which I use for running and cycling, respectively. Based on my experience with Garmin fitness products and many HRM watches, I’ve created a pros and cons list for the Forerunner 50.

Pros

Size/form factor - an attractive and sleek HRM watch that can display speed and distance.
Wireless data download - automatic wireless download of workout data is a cool feature.
Battery life - 12 months of battery life using a coin cell battery (CR2032) versus regular battery charging with GPS devices.
Garmin Connect website - uploading workout data can become addicting. Garmin’s online training site (currently MotionBased) is much better than Polar’s or the Nike+ site. Here’s an example activity on the future Garmin Connect site - Golden Gate Park Run (Forerunner 305 data). I don’t believe the Garmin Connect site is completed yet for Forerunner 50 support, which means the website features and interface will probably change come October. It is also my understanding that Garmin Connect will eventually replace MotionBased going forward.
Indoor use - can be worn at the gym on a treadmill or in a spinning class as a normal HRM watch, i.e. no one will stare at your big GPS device.
Speed/cadence sensor - track speed and distance of bike rides with this optional accessory. Since the sensor is installed on the rear chain stay, the Forerunner 50 can be used on an indoor trainer.

Cons

No GPS - means less accurate speed and distance data. And no ability to import/export courses or running routes to share with others.
Foot pod - an extra accessory that needs to be moved from shoe to shoe for speed and distance data. However, the design appears to be slimmer and better than Polar’s foot pod.
HRM strap - the Garmin HRM strap is comfortable to wear but Polar Wearlink HRM strap is probably the best on the market in terms of comfort.

Who should get the Forerunner 50? I would recommend the $106 Forerunner 50, Heart Rate version to anyone who works out primarily at the gym and wants to monitor their heart rate. Next, I would recommend the $150 Forerunner 50, Foot Pod or the $200 Forerunner 50, Heart Rate & Foot Pod version for the runners or cyclists who want to track their speed and distance in a sleek sports watch, but isn’t concerned with a small inaccuracy in data.

With that said, I wouldn’t recommend the Forerunner 50 to people looking for the most accurate speed and distance information that a GPS device offers. Additionally, if you are want advanced features such as virtual partner training (train against a digital person), courses (compete against previous workouts) or an altimeter, then go with the Forerunner 305.

A Forerunner 305 is only $165 after rebate and provides HRM, GPS and a barometric altimeter. Granted it’s on the larger side compared to the Forerunner 50, but it’s only 1.22 oz (34.5 g) heavier. With a $50 rebate, the Forerunner 305 is cheaper than the top of the line Forerunner 50 version, with more features and better accuracy. Unless you are hell bent on a sleek fitness watch, the Forerunner 305 is the better value.

Garmin Edge 305 And MotionBased Equals Training Bliss

Chuck — Thu, 22 Mar 2007 01:09:00 -0400

Since May 2006, I’ve been using the Garmin Edge 305, a GPS-enabled cycle computer, on my road bike. I also have the heart rate monitor (HRM) and the speed/cadence sensor accessories. As a data junkie, I absolutely love my Edge 305.

But I have to admit, I hadn’t used the full capabilities of the 305 until recently. At the end of May, a friend and I are going on a Giro biking trip through the Italian Dolomites, which means there is a ton of climbing. My friend lives in New York City, so I’ve been training All By Myself.

Thankfully, the Garmin Edge 305 has been a great training tool and has really helped me to stay motivated. I’m finally using the training features (workouts and courses with a virtual partner). Additionally, I’m using MotionBased, a web application that allows you to upload, analyze and visualize your ride data. MotionBased (MB) is a much superior post ride analysis tool to the Garmin Training Center software that comes with the Edge.

After each ride, I upload my ride data to MotionBased and I’m able to conduct post ride analysis, keep motivated to train and improve my performance. I want to point out that MotionBased is not limited to just cycling and supports many GPS devices (Garmin Forerunner 205/305, Garmin 60CSx, eTrex Vista Cx and more) to upload and analyze running, hiking, Nordic skiing or any activity you track with a GPS device.

Instead of writing a review on the Edge 305 and MotionBased, I’m going to provide a review roundup and highlight key features of the 305 in the remainder of this post and MB in a follow-up post.

Garmin Edge 305 Review Roundup:

Garmin Edge 305 cycling GPS system review from PocketGPSWorld.com - by far the best and most detailed review; covering specs, installation, features, user testing and analysis software.
Garmin Edge 305 Review from Arena Red - a good overview of the Edge 305 with comparison pictures of the 305 next to iPods and a Moto Razr.
Tech Review: Garmin Edge 305 by Jeremy Bostron - a list of positives and negatives comparing the 305 to the Polar 725 bike computer.
Mini-Review: Garmin Training Center for Mac from Arena Red - short review of the Garmin Training Center Mac version.

If you read the PocketGPSWorld.com review, you should have a very good understanding of the features and the wealth of data captured and displayed by the Edge 305. For someone looking for a simple cycling computer, the 305 is complete overkill. However, for the data obsessed, the Edge 305 is a dream come true. Highlighted below are the features that I enjoy the most.

Key Features:

Custom Data Fields - the Edge 305 allows customization of the following displays: Bike Computer 1, Bike Computer 2, Maps, Workouts and Courses. When I’m riding, I like to see my speed, heart rate, cadence, grade, distance and elapsed time in one view. On my previous bike computer, a Ciclosport HAC4, I was able to only see two data points at a time. On the Bike Computer view, the Edge 305 can display up to 8 data fields. There are 33 data fields from which to choose. Since there are two Bike Computer views, it’s possible to display 16 data points between the two views! With the 305, I spend less time pressing buttons, scrolling thru views and more time with my hands on the bars and eyes on the road.
Virtual Partner - when training by yourself, the Virtual Partner is the ultimate pacer. Used during quick workouts or courses, the Edge 305 displays how far ahead or behind you are relative to the Virtual Partner. Since I don’t have a training partner, I’ll take a virtual partner instead of no one.
Workouts and Courses - workouts are excellent training tools. Quick workouts (Distance and Time, Time and Speed or Distance and Speed) display a Virtual Partner to keep you motivated during your workout. You can also setup interval workouts based on time/distance and rest time/distance. But the most realistic training tool is the Courses feature. You can create or edit courses based on a previously recorded ride. Then you can race against the Virtual Partner on the course and see if you can beat your previous performance.
Cadence/Speed Sensor - is a single wireless unit, which is installed on the rear chainstay. The speed sensor is used when there isn’t a quality GPS signal or when GPS is turned off. Because the sensor is attached on the rear wheel, the Edge 305 can be used on a bike trainer. Most other cycling computers have two sensors, one on the fork for speed and one on the chainstay for cadence.
Data Analysis Software - the 305 comes with the Garmin Training Center software, which allows you to download and analyze your ride data. You can overlay various data fields (distance, elevation, heart rate, speed, etc.) and analyze your performance. Unless you have Garmin map products, the map view is very limited and only shows major roads and cities. This is were MotionBased excels and I’ll cover MB in a follow-up post.

My only complaint with the Edge 305 is the short battery life (less than 10 hours with a good GPS signal). It’s a rare event that I’ll ride longer than 10 hours, but that’s the one I’ll definitely want to record and review post ride. A current solution is a DIY battery charger, but that’s a little clumsy for this high tech cycling computer.

Furthermore, a great feature enhancement would be a low cost power meter, which would make the 305 even better and provide more data to geek out on. I would also like to see compatibility with Polar’s Wearlink transmitter and strap, which is the most comfortable HRM I’ve ever used.

Overall, the Garmin Edge 305 is an amazing GPS cycling computer. With GPS functionality, an HRM and a speed/cadence sensor, it provides more than enough features and data recording to blow away the competition. It’s also a great training tool, which keeps you motivated to ride farther and faster.

Polar adidas Project Fusion - Wearable Fitness Technology

Chuck — Thu, 18 Jan 2007 01:16:00 -0500

“Your shirt talks to your Running Computer
Your shoe talks to your Running Computer
And they all talk to you”

You may have seen this Polar/adidas marketing pitch for Project Fusion, which combines Polar’s latest heart rate, speed and distance monitoring technology with adidas adiStar Fusion apparel and running shoes. Project Fusion was awarded the “Running Accessory of the Year” Award at ISPO winter 06 by Runner’s World magazine.

“The results of the Polar adidas co-operation are the adiStar Fusion apparel and running shoes, which have been merged with the latest heart rate and speed and distance monitoring technology from Polar. This totally unique and truly revolutionary running gear has been built around the Polar RS800™ Running Computer. During a run, it collects all of the information from the sensors that are positioned in the apparel and shoe, then immediately informs the athlete. Everything is collated and translated into information the athlete can use such as: heart rate, speed and distance, cadence, route profile and calories burned. After the running session, all information can be downloaded to the PC, and added to the training diary.

The adiStar Fusion apparel have soft, heart-rate sensors built in. These machine-washable textile sensors work in conjunction with the Polar WearLink® connector - it just snaps onto the front of the apparel and sends all training data straight to Polar RS800™ Running Computer. No bands, no adjustments, no extra kit - just put the shirt on, snap on connector and start running.

In the midsole of the adiStar Fusion shoe is a special cavity that houses the tiny and very light Polar s3™ Stride Sensor. Because it’s internal, the Stride Sensor is more convenient and delivers even more consistent running speed and distance readings, without compromising comfort or performance. And all of the speed and distance information is sent from the very heart of the adiStar Fusion shoe straight to the Polar Running Computer.”

The training system is well integrated and very cool. The s3 Stride Sensor works and fits in the adiStar Fusion shoe similar to the Nike+ Sport Kit sensor for the iPod Nano. The main differences between the Nike/iPod and Polar/adidas systems are the plethora of running features and the HRM provided by the Polar RS800.

The Polar RS800sd (includes the s3 Stride Sensor) is Polar’s top of the line running computer. With this watch, you’ll get an HRM, running cadence, average stride length, target pace, running elevation profile and much more, see complete specs at Polar. The Nike+ Sport Kit is limited to distance, time and pace.

The total cost of the Polar RS800sd, adiStar Fusion apparel and shoes will cost $550+. You can save $120 by getting in touch with your inner MacGyver and invent a way to attach the s3 Stride Sensor to your shoe. I did with Glad Press’n Seal and my Nike+ sensor.

The Polar RS800sd is a great HRM watch for the running enthusiast or data analysis geek. When I say data geek, I mean it in the nicest way, since I put myself in this category. The problem with such a high-end watch, at least for me, is after downloading and analyzing the data the first few weeks, I’ll end up ignoring 3/4 of the watch features. I wouldn’t recommend purchasing the RS800sd unless you are a hard core runner and plan on using all of the watch features.

Otherwise, I would go with an iPod Nano with the Nike+ Sport Kit to add speed and distance feedback on your run. It’s hard to give a definitive recommendation for either system because there’s a trade-off with each… HRM or music.

Now, the primary reason I’m excited about the Fusion Project is the adiStar Fusion apparel. I already own a Polar RS200 HRM with the Wearlink transmitter and strap. The Wearlink chest strap is the most comfortable HRM strap that I’ve used because it’s made of cloth, whereas most HRM straps are a hard rubberized plastic. Despite being very comfortable, the Polar Wearlink strap will still slide down to my waist while I’m running.

It’s completely fine when I’m cycling or during a spin class, but it’s a pain in the butt while running. I’m constantly re-adjusting the chest strap when I’m pounding the pavement. However with the adiStar Fusion shirts, I can just attach the Wearlink transmitter and not worry about it slipping. The shirts can also be used as a base layer during cold weather runs.

So my ultimate solution is the iPod Nano with the Nike+ Sport Kit, Polar RS200 with a Wearlink transmitter and an adiStar Fusion shirt. I have the best of all worlds… music, speed and distance, and heart rate monitoring. Then I can geek out over the data during my run to keep motivated! Or pre-occupy myself, so I forget that I’m ~~suffering~~ running.

Fitness Gear That Motivates

Chuck — Wed, 03 Jan 2007 15:56:00 -0500

With the New Year, many people have made goals to lose weight and exercise regularly. Whether you are starting an exercise routine for the first time or a fitness fanatic, staying motivated is the key to getting fit and maintaining it. Motivation can come in many forms, such as training for a race/event, an exercise partner or the possibility of dessert with every ~~five~~ three mile run.

To help you reach your weight loss or exercise goals, here are some fitness tools that can keep you motivated to workout.

Heart Rate Monitor (HRM) - To get the most out of every workout and to ensure you are pushing yourself to the right limits, get an HRM. I prefer Polar HRMs with a wearlink transmitter, which has a flexible cloth chest strap. To learn more about HRMs check out, Heart Rate Monitors - What’s Your Max Heart Rate?
Nike+ iPod Sport Kit - If you already own an iPod Nano, this will be the best $30 you’ll spend to keep motivated on a run. I’ve been using the Nike+ Sport Kit for the last several months and I won’t go for a run without my Nano and Sport Kit. I love knowing my current pace and getting a message from Lance Armstrong or Paula Radcliffe after I beat a personal record. Additionally, the Nike+ website provides run/goal tracking and community features to inspire more running.
Garmin Forerunner - Get the accuracy of GPS to monitor your speed, distance, pace and calories burned with the relatively sleek, wrist-mounted Garmin Forerunner 305 (HRM) or Garmin Forerunner 205. For cyclists, check out the Garmin Edge Series GPS cycling computers.
10 Minute Solution DVDs - Do you have 10 minutes to spare? Whether it’s pilates, yoga, kickboxing or dancing, there’s a DVD available with multiple 10 minute workouts to target and isolate various body parts. If you can’t get to the gym or go for a run, watch and follow along with one of these DVDs to get a quick workout.
Traineo - A free and simple website that allows users to report goals, workouts, diet and weight to a group of friends who monitor and support each other. Users can also join larger support groups to get encouragement from people with similar health and fitness goals.

If you are new to working out or getting back on the bandwagon, try to set manageable goals. Small wins obtained quickly will keep you motivated to work harder. As you achieve these smaller goals, keep on raising the bar and soon enough you’ll achieve that ultimate fitness goal.

Heart Rate Monitors - What's Your Max Heart Rate?

Chuck — Fri, 01 Sep 2006 15:33:00 -0400

Heart rate monitors (HRMs) are a great training aid and fitness tool. For me, an HRM keeps me honest during my workout. There are some days I am mentally and physically ready to exercise. Other days, I’m mentally out of it and just don’t want to push myself. These are the days an HRM maximizes my training effort and ensures that I have a good workout.

Some people don’t need to use a heart rate monitor because they are in touch with their body signals and know how hard they are pushing themselves. I am not one of these people. Coming from a team sport background, I pushed myself based on my competitiveness. When I switched to endurance sports, I really needed an HRM to help me monitor my training level. Using an HRM has definitely helped me train more effectively.

Are you in the process of buying an HRM? Keep in mind, getting a heart rate monitor is so much more than the HRM watch itself, it’s just the start. For runners, I found a great intro to HRM article on Runner’s World, Follow Your Heart. In the article the max heart rate calculation of 220 minus age is debunked.

“For years, everyone (including us) has been telling you that the best way to find your maximum heart rate (MHR) is to subtract your age from 220. Sorry about that.
Turns out that’s not the most reliable method, at least not for healthy, fit individuals like the readers of Runner’s World. For most of you, two newer formulas will prove far more accurate:
(A) MHR = 208 - (0.7 x your age)
(B) MHR = 205 - (0.5 x your age)
A small group of Runner’s World staffers recently tested these two formulas, and reached the following conclusions. Both seem to work almost equally well for runners under 40. For runners over 40, formula (B) appears to be more accurate. We now believe that (B) is the single best formula for predicting maximum heart rate, and we’re adopting it as our Runner’s World standard.
Then there’s option C: Of course, no predictive formula can ever be as accurate as an honest-to-goodness, all-out field test. You can conduct such a test on a track or a moderately steep hill, which may work better if you’re not an experienced track runner. And by the way, since all the workouts in this article depend on an accurate MHR, it’s worth the effort to take this test. You’ll need to wear a heart-rate monitor for it.”

I prefer option C, the all-out field test, to figure out max heart rate but it’s a grueling, painful effort. Runner’s World also had an article for the best HRMs under $150, Don’t Skip a Beat. I’ve listed a few HRMs from the article that are under $80:

I couldn’t tell the publication date of the Runner’s World article but I suspect it’s a few years old based on the lower prices found on Sprenzy.

Personally, I’ve owned a Timex Ironman HRM, Ciclosport CP29, Polar RS200, Ciclosport Hac 4 plus and a Garmin Edge 305 GPS HRM. The latter two are cycling computers/HRMs. I’ll do a follow-up post on the cycling computers/HRM in the near future. The Ciclosport CP29 heart rate reading fluctuated too wildly for me. I am extremely happy with the Polar RS200.

It’s not necessarily the Polar RS200 watch that I like. It works fine just like all other HRM watches that I’ve owned. I tend not to use all the great watch features after the first couple of weeks. What sets the Polar HRM apart is the chest strap.

Polar has the Wearlink coded transmitter and belt set. It’s the only soft fabric transmitter according to Polar. Most chest straps have hard rubberized transmitters, which can be uncomfortable to wear. The Polar Wearlink chest strap is very comfortable and conforms to your body much better than the harder plastic chest straps.

Polar states that the Wearlink strap is “compatible with all Polar heart rate monitors.” If you are looking to buy a Polar HRM, I would recommend looking for a model that comes with a Wearlink strap. I think this is the most important component to an HRM. If the belt strap isn’t comfortable or constantly slips, you won’t wear it and use your HRM.

For all of you gym rats, most exercise equipment such as treadmills, elliptical machines and Stairmasters have heart rate sensors. These sensors are generally compatible with analog transmission HRMs. The downside with analog transmission is the possibility of interference from other HRMs. On the flip side, digital transmission HRMs reduce the likelihood of interference but may not work with gym equipment. The Polar Wearlink “coded transmission eliminates interference from other HRMs” and still works on most gym equipment.

Good luck with your HRM decision. I really enjoy using my HRMs and any gear/gadget that promotes healthy living and exercise is a good thing!
