For the Coaches:
My question for further discussion is simple; How to know when we are pushing too hard for too long?
Lately I have been struggling with my HR and Resting HR: Resting always in the 90 - 100 bpm range while on the bike I see that even after chit-chat pauses (5 minutes long) my HR stays above 130 bpm while my mates are roaming 80 - 90 bpm. I visited a cardiologist to check things out and before a 24hr Holter check I took a 2 weeks break off the bike, mostly doing yoga workouts and keeping up with the strength training plan. Result: 70 bpm resting HR, the cardiologist thought I was nuts.
Afterwards I took my bike again and started riding, resulting in the same previous situation. I feel the friends I ride with are much stronger than me so I push hard for the entire duration of the ride (plus I feel bad not taking my turn at the head of the column and face the wind).
Might this be a sign of too much cardiovascular load?
Should I aim for another break and follow a Training Plan with solo rides?
