4 hours of sleep does not make for a good workout day. I'll be collapsed on the couch until my IV of coffee starts working. ;)
In running news, it was suggested to me to look at the C25K program to help me gently get back into running. I downloaded a free app and I'm going to start at Week 4 Day 1. If the program works I'll be back up to 3 miles in 4-5 weeks.
