Wow....how much vertical gain did you attain for the 82 miles? Sounds like an impressive ride. I know you didn't reach your goal, but I wouldn't be upset with your accomplishment.

I did a 43 mile ride on Thursday with 2,011 feet of climbing, and that was a fun ride.....minus 8-10 miles of badly paved road which made for an assload of extra rolling resistance, which also wasn't exactly flat. Legs are feeling really strong though now. Just be sure to recover well, and you'll be back even stronger.
