I just looked at my Training Peaks dashboard and realized that the Monterrey 70.3 file recorded by my Garmin 620 measured 70.6 miles â€“ pretty accurate for a running specific watch! I donâ€™t have one of the new Fenix 2 triathlon watches, so I used the Forerunner 620 â€“ a watch meant just for running â€“ to record my HR throughout the race. It doesnâ€™t do the fancy bike stuff (like pair with the Vector Pedals), and you canâ€™t change sports or do a multisport mode during the race, so itâ€™s definitely not as good as using the Forerunner 910 or the Fenix 2, but it did record my HR and I wanted to see the running form metrics that only the 620 and Fenix 2 are capable of recording.
Check out the file here on Garmin Connect. Obviously only the last 13.1 miles are runninng, but I did start a new lap as I ran through T2.
