Ride with a bunch of youngsters under 35 on my group rides from the LBS. Today was 55 miles at 100 degrees and an average speed of 20 for the first half till one of the kids blew up as his leads were at 23. Can not blame him because it was his first ride on a new Madone. Overall was 18 mph.
I am 64 and back on the bike after 20 plus years so am still getting fit. Need help on the new fuels IE: gel packs and so on and how often to eat them.
