Finally got a nice working HRM yesterday - been without one since mid-90's and forgot how AB FAB they really are!
Anyway along with a bunch of info from yesterday's ride, there's this, which I'd like to get BFer's interpretations on:
while steady tempo riding, middle of ride so already well warmed up, on a flat section, positioned on the hoods:
riding in a 79 inch gear - 100-105 rpm - reading 23.6 to 24 mph - my heart rate was steady 140-142
same section, now riding in a 91 inch gear - 85-90 rpm - also reading 23.7 - 24 mph - heart rate was 150-154
How would you interpret this...
