OK, OK, I took all of your recommendations except...staying off the bike. Which starts today. I'm off it totally for a month or two. It's going to kill me but I need to get this resolved.
So to recap what's been happening with the fatigue and what I've been doing;
I get fatigued on the bike since the beginning of the year. I do at least three doubles a year (on the single of which I've completed two so far) with up to 7-8,000 miles a year. I'm 56 and and 190 pounds. I know, I know, I should lose some weight but I've always ridden at this weight. Last year, we started riding the tandem and this year to date have ridden over 2,000 miles on it including 600 last month in a week down the coast from SF to LA on the AIS ride. Had a great time.
I do notice, if I take a week off before big rides, I get real fatigued (on climbs primarily) for the first 30-40 miles. On the AIDS ride, I suffered the first day, then did nicely the next six days.
I've had physical's (including stress tests), including blood work and everything shows I'm healthy as can be. A Natureopath did say my hormone levels are down and I've been doing supplements for the last month. Protein intake has been increased.
So...I'm still feeling it. I can suffer through it but it just ain't fun like it used to be, because I hate being a slug.
So, the only thing I didn't do was stay off the bike for more than a week. So, today, I'm done for a while.
Any comments are welcome.
