2 mile warmup, 3x150 striders, 4 x mile repeats with 1 min rest, and 3 mile cooldown. Splits were 5:46, 5:44, 5:47, and 5:49. Was planning to do 5 but my legs just weren't in it today. I felt really good after the first one but then it got a lot harder and during the 4th I decided I should just keep it at 4.
