Took a different route to work today, a more hilly one. Took me longer to get to work and I was very tired when I arrived. I don't know if it was the route though, I had an indoor soccer game last night at 10pm and I had to play almost the whole game due to lack of subs. So I didn't get much sleep and was tired before I even got on the bike. Definitely taking the easy way home after work.
