Running intervals 1:00:00  12.5 km (4:48 / km)
Turned up a bit late and missed the first 90 seconds on, but caught the group and joined in. I held on with the alpha males up the hill for about 8 minutes, but dropped off before the turn around. I held my own on the way back until we got to the end of the 30 second efforts.
I then ran a lap of the tan to pick up another free Powerade.
