Hi. The only thing I didn't agree with Truman on is in CTR, every ride I've ever been at, if riding 25 miles, you do get your 10 min. to pulse down but you also have a mandatory 1/2 hour to 45 min. to rest.
I thought in endurance you are checked for pulse and if it's down, then you are ready to go? Correct me if I'm wrong. Thanks.
