Roller derby (Skating) 5:00 
Laps!!!!! Was mostly in the lead off the line, but I skated not all the way to the inside for the first few laps, since I wasn't actually officially doing mine and was just there to skate.
Then Nay (my endurance buddy when I go to sunday speedskating, who's also my teammate) sat behind me for a few min, then she went ahead, then I got to focus on trying to catch her, and I passed her on the last lap or so but we basically finished at the same time. I wasn't super duper going all out, but it's been awhile since i've been in a race situation where I get to focus on catching someone just ahead of me, so it was fun! Was very tired after :P
