Nice little TT for comparison

After a good 8 week build, averaging 15,280' of vert per week the last 4 weeks, I decided to look a little less at vert this week and do some faster running on rolling terrain that allows for much faster running. I went back to one of my favorite out/back trails this morning, a trail that I used to run alot a year ago. Today would be an Easy run out and a Tempo on the way back. There's 675' of climbing on the way out and 625' of climbing on the way back. When I had done this in the past an easy out effort would be about 49/50 minutes and a hard effort coming back would be 44/45 minutes, with my best being 44 flat. Going back through my blog I noticed I had my fastest time ever on this out/back almost exactly a year ago 2/27/10, 47:43/44:17 = 1:32:00. Today I'd be happy with 50 going out and 45/46 coming back. It took me a bit to get going this morning and even told myself I'd bag the Tempo coming back if I didn't feel better by the turn around. Within the first 30 minutes I'd see my HR was in the mid 130's going up some of the bumps and I was breathing like it was in the mid 150's. I thought for sure that this was not the day to be testing myself. Of course, what's been the usual the past few weeks was the usual again today, I was finally warmed up after about 35-40 minutes. Did the out portion in 48:32, well under 50:00 with an average HR of 128. Once I got moving on the back Tempo I started feeling really good and went 41:22 with an average HR of 146!! WTF's up with that? That's a good 2:30 faster than anything I've done on that trail before for a total time of 1:29:55. Needless to say I'm quite happy with where I'm at right now.
