The Forerunner 735XT Heart Rate Monitor Watch is compatible with both speed and cadence sensors for cycling. The watch can be used for swimming both in the pool and in open water. The HRM-Run strap will only calculate running data (cadence, stride length, ground contact time, etc). The HRM-Tri calculates all of the running data and stores heart rate data when underwater, then forwards it to your wearable at the end of your swim. Both the 735 and the 920 will be able to monitor courses and locations.
