The Workout app offers a choice of tracking either indoor or outdoor cycling sessions, which makes you assume there’s a difference in monitoring rate between the two. However it wasn’t immediately clear from my tests. Raising your wrist to look at the Watch when cycling makes the normally short delay before the screen turns on seem all the longer. A mount for the watch would be better (such as the Var CyClip, www.thecyclip.com), but then your iPhone would probably do just as good a job. The Watch battery survived a three-hour morning bike ride with enough battery left over to perform the rest of the day’s activities, although the Power Reserve mode (which turns off heart-tracking) may be better – though less accurate – for day-long treks. The Apple Watch isn’t compatible with and cannot read data from Garmin-owned ANT+ devices, but you can connect a Bluetooth LE heart-rate strap, which will ensure better data monitoring than any wrist-based wearable can currently offer.
Tim had some issues with the Strava app for the Watch but it’s very popular on iOS and we hope it gets developed even further.
