This morning I wanted to do some hills. I found on a couple of my earlier recovery attempts that I could run a harder effort up a steep hill going slow with less hamstring pain than that same effort on the level. I felt like it was because of the shorter stride length. At the same time running faster down the hill lengthens the stride back out but the easier effort seems to put less strain on the hamstrings.
I have a mile long hill by my house that climbs 240 feet. The sign at the top calls it a 6 percent grade but the first and last 200s taper off a bit. I started with a 3 1/2 mi. warmup on the level at about 8:45 pace then down the hill in 7:22 back up in 9:28 then down in 6:55 which is faster than my current mp but probably a slow mp effort with the hill. then back up in 8:08 which was definatly a threshold effort.I didn't plan on going that hard on the last hill but the hamstring felt strong and I couldn't resist. I felt pretty good since this is the hardest effort I have run any distance in 5 months.I finished with 1 1/2 cooldown with a total of 9mi. total time 1:11 overall ave. 8:26
