Looks like you were running 90-100m forest intervals. (corrected) Have you done that before?
90-100m? Yes looks like Charlie's getting some speed work in!
About 100 s. On the trail. Thought it might be good for the L hamstring, and I think it was, but had to cut it short when I tweaked the R one, so icing and taking it easy for a while. Felt pretty good until suddenly it didn’t.
Where do you turn around? Somewhere close to Pine Tree Park?
Exactly. Start was at a sugar maple just past the side field, finish at a very decrepit old root stock across from pine tree park.
