I posted here a few weeks ago about my having no power on climbs and it was suggested that I try more protein, eat 250 cals an hour (when doing long rides). I do double centuries (two so far this year finished, including Devil Mountain Double). I'm not a fast rider but have many years experience. I'm 56, 5'9" at 188 pounds. Yeah, I know I should take off a few pounds. I have a very good diet, eat lots of veggies, only eat fish and chicken when I'm eating meet.
So, this is the first year I've experienced this. I ride on average 5-7K a year in mieage an complete 3-5 doubles in a year (29 so far).
I've been experiencing what I feel is a rapid heart rate and no power in the legs. Had the heart checked with a Holter HR monitor for 24 hours and nothing except a skipped heart beat on occasion. When I did DMD staff ride a couple of weeks ago, the first 20 miles going up Mt. Diablo was really bad, then, I was able to ride through it and completed the double in decsent form, not having much problems with the sympoms.
So, on a 30 mile ride yesterday, I felt terrible with fatigue. I've only ridden 60 miles in teh week since the double.
Man, I'm bummed.
