I just finished a 23.156km cycle that lasted about 0hh:58mm:10ss !
Still haven't finished Local Hero by SufferFest yet. Going for a 90-minute ride at a high effort level is proving harder than I thought it would be. Though, I'd be lying if I said I wasn't enjoying it.
The ride today was pretty good, after my legs warmed up. I know I need a smaller bike, but I'm pretty convinced that I wont pull the trigger until I get to ride one first, and I don't know anyone else with a 56-58cm road bike -- so it'll have to wait until I go to Kelowna w/ 
Regardless, the pyramids were easier than they were last time, which I suppose is progress. Made it through the first 3 or 4 laps of the 5 lap race, then hit the wall right around an hour apparently. Now I'm just hunkering down and gettin' ready to eat some food, and see if I can't get my ANT+ bike sensors to talk over Python.
