Intervals 15:00 [4]
Went up 3 of the trails going from down near the beach up to near 4th, and each time went back down, then traversed a bit to the next. Went a bit slowly at first, since had gone hard up the hill but then usually a decent pace down and across (since nate dragged me).
3:43 - up the first hill on gravel trail
10:13 - down, then along to the next hill
5:23 - up the stairs in the ravine, then flatter gradually up and twisty trail near the end picking up speed.
8:22 - down and along to the next hill, nice bit of downhill on a softer trail
5:21 - up the last hill from near the beach, reasonably steep at first then a bit flatter with some smaller uphills
