Monday 7.6 mile run, easy pace. Tuesday cycled to the trail, about 16 miles round trip, and ran 8 wen I got there. Modest 8 1/2 min pace. Today did my long run for the week, again cycling 16 miles to the trail, then running 12. Wore my HRM for the first time in a long time, I should have been wearing this sooner, but figured these last few runs before the marathon I should make sure to keep my HR at MAF or less. Well that started around 8 1/2 min/mi pace but the last half I slowed down into the 9 1/2 pace range, and was still a couple beats over. Not quite as good as I was hoping for, especially considering it was less than half the marathon distance. Should be much cooler at the marathon though, that always helps. In fact I am getting nervous if the temp takes a big swing down I won't be prepared for the cold! Last year at the marathon it was 29F at race start! Coldest I have run lately is 2 weeks ago we had a bit of a cold snap and I had 2 runs in the upper 50's, that's it. Today was about 80F when I ran, this isn't helping. I can't just go from summer burning pavement to sub freezing, need some acclimation... I was chilled on those 50 degree runs lol. Just hoping these warmer temps will hang around until next weekend, or at least stays above 40. (edited to add: my concern for the cold is due to running in bare feet without acclimation, the rest of me would be fine).
