For the past couple months I’ve been experimenting with MAF training, running at a targeted heart rate with the goal of improving my aerobic base. I’ve been using a simple heart rate monitor (HRM), but I always run with my iPhone and it would be nice to record my heart rate data alongside all the other information my phone collects.
All iPhone compatible HRM sensors work by attaching a dongle to the iPhone.
I’m only looking at Runalyzer and Wahoo because they both work with a wide range of apps. (Runalyzer compatible apps, Wahoo compatible apps) The other HRM options I found, Garmin’s and Digifit’s, only work with their own proprietary apps.
Wahoo uses the ANT+ wireless protocol (2.4 GHz) and requires an ANT+ compatible HRM strap. Runalyzer claims to work with all existing analog HRM straps (5.3 kHz). Runalyzer’s hardware dongle is slightly shorter and wider than Wahoo’s.
Unfortunately, RunKeeper, my preferred running app, doesn’t support anything except the Wahoo Key. But I tried iSmoothRun again and was very impressed with how it’s progressed since I last tried it–enough to switch.
So, I’ve decided to try the Runalyzer dongle with iSmoothRun since I can keep using my existing Omron HRM strap. It’ll be here in a few days.
