Product Description


Adds Heart Rate-Based Training to the iPhone
view larger

The Wahoo Run/Gym Pack for iPhone transforms your iPhone into an all-in-one training partner. Combining everything you need to track your training, the Wahoo Run/Gym Pack for iPhone features the Wahoo Key and the Wahoo Soft Heart Rate Strap - great for tracking heart rate while you run, ride your bike, or go to the gym. Wirelessly measure your heart rate while you workout with your iPhone, tracking calorie burn, minimum/maximum/average heart rate, and time spent in each heart rate zone for all your workouts.

Connect With Popular Apps

Monitor your fitness stats in real time as you run, ride, or go to the gym through our free Wahoo Fitness App or any of our partner Apps, such as Run/Cyclemeter, RunKeeper, MapMyRUN/RIDE/FITNESS, Runtastic, and Endomondo. For a complete list of compatible Apps, visit www.WahooFitness.com/Apps.

Upload to Training Websites

Workout data is easily and wirelessly uploaded to popular training websites such as TrainingPeaks, MapMyRUN, Nike+, Garmin Connect, and Strava so you can track your fitness over time and share with friends. You can also e-mail workout data to yourself or your coach.

Ultra Low Energy

The Wahoo Key has no internal battery and requires no charging. The Wahoo Soft Heart Rate Strap runs on a replaceable coin cell battery which lasts up to two years and sleeps during inactivity to conserve power.

Includes Wahoo Key and Wahoo Soft Heart Rate Strap
view larger.

Simple to Use, Compact, and Rugged

Simply plug the Wahoo Key into your iPhone, snap on the Wahoo Soft Heart Rate Strap, pair with your favorite fitness app, and begin your workout. The Wahoo Key is small, weighing only 3.5 grams, so it's easy to carry while you run, ride, or workout.

How It Works

  • The Wahoo Run/Gym Pack is compatible with many popular Apple products, including iPhone 3G, 3GS, 4, and 4S, iPod touch 2, 3, and 4, and iPad, iPad 2, and iPad (3rd generation).
  • Plug your Wahoo Key into a compatible iPhone, iPod Touch, or iPad where you would normally plug in your charger. Thoroughly wet both electrodes on the heart rate strap with water or electrode gel. Snap one end of the heart rate strap into the sensor, wrap the strap around your back, and snap the other end into place. Make sure the sensor is located on your sternum or just below your breasts and that the Wahoo Fitness logo is facing up. Adjust the strap to create a snug, yet comfortable fit. Once in place, move within 5- 10 feet of your iPhone with the Wahoo Key attached to begin the pairing process.
  • Download the Wahoo Fitness Utility App for a step-by-step setup guide. Use our free Wahoo Fitness App or any of our partner apps to begin tracking your fitness.
  • If you do not get a reading, or the readings are erroneous, ensure that the electrodes are wet and have good, snug contact with your skin. Your heart rate strap 'sleeps' with inactivity and 'awakens' with good electrical contact, so a brief physical warm-up may be required.
  • The Wahoo Key can receive data from any Wahoo Fitness or other ANT+ sensor(s) such as heart rate straps, stride sensors, or speed/cadence sensors and can read multiple sensors at the same time. Each sensor has a unique ID code that, once paired, will be recognized when it is activated and within range of your iPhone with Wahoo Key attached.

It fits well, works great, and it's comfortable.
This heart rate monitor works very well and maintains it's connection to my iPhone app (Digifit) during every type exercise I have done in the P90X2 program.

I actually purchased two of this item... one at Best Buy and the one here on Amazon which was $10 cheaper. Both work flawlessly.

There were absolutely no problems fitting the strap or getting an immediate signal. There has been no loss of signal no matter how strenuous the workout. The product claims that you should be within 5 to 10 feet of the sensor, which is not a problem when working out. However, I've found that it works within a much better range... around 20 to 30 feet before the signal is actually lost.

I purchased the item for my stationary Gym workouts and my only gripe is with the WahooFitness iPhone App. There are only two workout types available, Biking or Running with specific options that correspond to each. This is called the "Wahoo Fitness Run/GYM Pack" after all; it's truly inadequate that there is no provision in the software for Gym workouts.

What are you supposed to do if you're not Biking or Running? I do this...

1. Set the workout type to "Running".
2. Turn off the GPS options since you're not really going anyplace.
3. In the settings, only activate iPod Control Page #3 (it's the most generic screen with the fewest references to Running or Laps)

Using those options, for your stationary Gym workouts, you can track Heart-rate, Calories, Time, Burn Rate, Max/Average BPM, and time spent in each heart-rate zone. There is only one minor flaw and that you have a "lap" button at the bottom left next to "pause". Again, there is no need for this "lap" button since you're only doing a stationary Gym workout. Everything else works fine and you can Pause, Resume, Stop and Save your workout to history.

I use the Wahoo Fitness Run/Gym pack with RunKeeper Elite on my iPhone. It took about 20 minutes for me to figure out how to get it working with my RunKeeper app, but I am not the best at that kind of thing. Once I got it working, it works LIKE MAGIC: I can monitor my heart rate on my iPhone, see/hear when I am in which training zone, and the heart rate data is overlaid onto my walking/jogging route data in RunKeeper. I can see exactly what my heart rate is at any given time and place in my workout. Highly recommended.

The product was solidly built and sturdy, however it never did work for me. I was able to pair the HR transducer with the ANT dongle for the iPhone, but the HR was not reliably telegraphed. The first strap I was sent did not work at all and I was sent a replacement strap by the excellent customer service reps at Wahoo. This new strap did telegraph my HR at times, but the connection was sporadic. It seemed to function better at resting heart rates. At higher HRs (150+), the connection would usually read much lower than my actual HR verified by counting or using the handgrips at the gym.

I am about 30 lbs overweight, so I'm not sure if the extra layer of fat was impeding the signal. I even used electrode gel to try to give a better connection, but it didn't help. It was kind of disappointing, so I returned the monitor to Amazon since I don't really have time to keep trying to troubleshoot this product. While most reviews are positive on Amazon, there are several negative ones, so perhaps there is some sort of defect that affects a minority of the transducers or straps.

***UPDATE*** JAN 10 2012 ***UPDATE***
After notifying Wahoo Fitness support and corresponding through email for about a day, I received a premium heart rate chest band AND a Wahoo Armband for iPhone a week later (I live in Hawaii.) I've been using the Ant+ and Heart Rate Belt with my iPhone 4 for a few weeks now, along with the Wahoo Fitness App. The app is pretty straightforward and simple (to set up) for my needs. I also have the Digifit App but haven't recorded a workout with it yet. My primary purpose is to track my heart rate during LSD Cardio and with workouts from P90X, P90X2, Insanity, Asylum as well as Tabata related workouts. The heart rate belt is comfortable and fits a big guy like me with plenty to spare. I believe this will be an excellent tool for me to use in order take my fitness to a new level.

Well I can't honestly give it a full review yet, ordered it and it came fairly quickly. When I received my package I quickly opened only to find that my heart rate belt was missing. Totally bummed, was looking forward to trying it out today. Watched videos by Wahoo and the YouTube channels, spent quite a bit of time looking at all the apps on iTunes.
Anyway... contacted support, waiting to hear from them. I know its Christmas and Im sure they are incredibly busy because this product seems like an AWESOME Christmas gift. I'll update my review once everything gets resolved.

I tried using this with my iPhone 4 and continually received the "This accessory is not compatible with iPhone" error message.

After doing an extensive search online many people stated that lint/dirt/etc within the phone's docking port could cause this problem. I thoroughly cleaned the port with a toothbrush and shopvac but still received the message every time I plugged in the ANT+ key. Needless to say, I never got the thing to work and returned it. Unfortunately, Wahoo's Bluetooth heart rate monitor is not compatible with the iPhone 4 so I'm out of options.
