My fastest "ride" was 26-something for 45 minutes in a crit. Other than crits, I did an 80 mile road race in just over 3 hours for 25.something (ok, so it was one way and there may have been a little wind but there was also a net elevation gain), and 43 mile rolling/slightly hilly road race at 23.4. I think those were pretty fast but not nearly as fast as the guys who won, or the higher categories. FWIW, I was blown out of the water when I found out that the winners of the elite nationals road race did 120 miles at over 26mph.
55mph on a downhill is my personal best, although there is a guy I ride with that has done well over 60 on the same hill. I've tried to get his wheel the last few times we've gone down it together but if he starts from behind me, he goes by so fast that I can't accerlate on. I have to start with him next time.
You're a climber and he's probably a sprinter?
