Roadracing and heartrate

Early last year I wore my Forerunner 305 and heartrate sensor out on track for a session around Buttonwillow Raceway. You'd think being on a bike with 160+ horsepower would mean it does the work while you just sit there, but folks what have actually done it will tell you different.

Here's my HR chart.



A friend is a serious triathlete and wore the monitor for a session and he was averaging about 30bpm less, but he can run 7:30 miles at 130bpm... so that isn't much of a surprise. He was trying hard, for him.

Another friend had us all worried when we tried it on him, because he was 190+ bpm. We were convinced he was holding his breath for about 2 miles of the 3 each lap. Remembering to breathe can be hard.

Here's the layout plotted by the GPS track.



All in all it is sort of a combo of cardio and weightlifting.
