Had a few rides in a row where I don't have any stamina and my heart rate seems to go high and stay high. Two weeks ago my heart rate was recovering 50-60 beats per minute in the first minute after stress but today I tested it twice at close to 30. I came close to quitting today on a hill that hasn't had close to this effect before.
In addition, I seem to be having at least daily bad cramps in the big leg muscles.
Neither of these are normal for me, related?
