Went to the Y to play basketball with the guys from work:
Team A: David West, Ernest Howell, Chris Lowe, Johnnie Sikes
Team B: Derrick Drake, Adam Socha, Matt Lowe, and me
Team A won 3 games to 1. All that sprinting was rough, and I can't shoot or dribble worth a crap. We played 4 games in a little over an hour, and we only rested a couple of minutes between each game. I was guarding Chris, so I pretty much ran the whole time. 4 miles is an estimate, but the effort felt like 10 miles or more.
Update: My upper body, hip flexors, and butt are still sore two days later.
