I have a new 20 mile loop. kinda short but I'm gonna work with it for now. it features several nice climbs including one killer at the halfway mark. so far I haven't been able to get up it without stopping briefly to rest for about 60 - 120 seconds. I'm sure i could make it with my other bike that has the triple crank but this old school cromoly steel '80s era 10-speed just kicks my a**. I'm getting better at this killer hill and I know that at some point I'll be able to make it without stopping. I got higher up the hill yesterday and rested for less time and it was only my second attempt.
