Max Heart Rate cycling to work is 186bpm!

Used my Polar Heart Rate Monitor watch with my new T31 Transmitter strap yesterday. Downloaded the logs of speed, distance, altitude and Heart Rate to the computer (over IR link). You can see that my 13miles commute is made up of a lot of stop/start cycling. The Altitude is based on temperature (I think) therefore isn't that accurate - I'll try correlating it to a GPS log to make sure alt/distance is accurate. However in terms of HR logging its pretty revealing. I tend to cycle flat out all the way - peaking at 186bpm just before Clapham South Tube station (there's a little hill I try and sprint up). Going to add Cadence sensor to the bike to get a better idea of what gear I'm in/effort.

  1. I agree with you on the altitude measurement. I rode with a GPS a few times before getting my Polar and the GPS definitely seems more accurate in terms of absolute elevation. I used the GPS to calibrate by Polar, but the fact that I went to altitude -130 on a ride recently makes me think its still ok (ok, the Seattle area is definitely close to sea level, but I don't think we're that far below it!).

    That said, the Polar seems accurate enough from a relative perspective. My elevation graphs correlate well with those I've seen from my GPS.
