For two reasons:
1. He has a work-related thing in the evening (free food and beer)
2. This weekend, he biked 12 miles to Minneapolis, ran a half marathon (came 17th, not bad considering he'd never run a race before), biked home, and then went and hiked 34 miles on the Superior Trail. Needless to say, he can barely walk right now.
If someone else wants to organise practice, please email him and post here.
