Something occurred to me on my ride Saturday - you are training for a back to back ride event, and back to back training rides are included in your program. In light of that, you'll want to pay particular attention to post ride recovery nutrition. If you weren't doing back to back rides, you could get away with not being as diligent about this. But since you are riding 2 days in a row, right after your ride (within 30 minutes or so) you should try to take in 300 - 400 calories in recovery drink or other good fuel.
Thanks Wahine for bumping this thread up again (and for your good comments) so that I remembered to post that note. As we get older, apparently we don't just need more recovery time, we also need memory rehabilitation. :rolleyes:
