Three hours. On the trainer. Longest bike ride EVER.
Man, the sore legs weren't too bad. The trainer wasn't even too bad - I put in Fellowship of the Ring and geeked out. My butt, on the other hand, was KILLING me. I was wearing bike shorts but I'm just not quite conditioned yet.
Otherwise it went really well. Next up is tomorrow's 1:45 run. Hopefully my legs will feel at least somewhat fresh in the morning.
