Rode our Hills R Your Friends ride on Saturday. 74 miles with 9650 feet of climbing, ouch. Crosses the Laurel Ridge 4 times. Got serious cramps on the third climb but drug myself to the finish.
Anyway on to the question. Got home and checked the bike computer. Said my max HR during the ride was 212! Normally never get much above 160 which is where I have my red zone set. Spent 45 min above 160 during the ride. I have registered in the high 180's at times but never above 200.
So is this possible or a computer malfunction?
