No GPS, so distance is a guess. There was also some elevation. Warm up 5 hard sprints up alongside Cougar Creek from near the bottom to the road at the top. About 3:30 up, then jog back down and recover. Ran back down to collect my jacket and met up with a runner who was doing the sixth interval as per the original plan. Ran the last half of it with him. Then to the Iron Goat pub for duck wings ("good" fat)
Abdominal muscles were tight and tired from all of the poling in last night's xc ski lesson, to the point that it limited my breathing during the hardest efforts on a couple of the reps.
