Longer week

I managed to up my total mileage this week - a long run on Sunday, followed by regular runs - with 2 of the runs, I mixed in some 400 meter repeats. So far, the hamstring is still holding up... I do hope it continues to do alright - I'm not sure the physical reaction once I start hitting the track a lot harder and more frequently.

Base - 28
Intervals - 4x400 @ 1:14 during one 6 miler, Untimed during another 6 miler (400, 600, 600, 400, 400)
