Yeah, another DNF. This time @ mile 16. I was cruising along around 11 minutes a mile. Some faster, some slower, but generally at 11 minutes. I went by RPE instead of HR and everything seemed to be okay...until I started chaffing. My HRM belt was messing with me. My nipples were not feeling good against my shirt. My shorts decided to mess with me as well. Yeah, too much info, but you get the idea. All was going well until after the half-marathon point, then it went south.
Once I got to mile 16, I decided to bail simply because the fun run wasn't fun anymore and I didn't need to cause a monsterous chaffing incident with myself. I still have scarring on my chest that looks like that damn Suunto ANT+ belt.
So from now until I completely heal up or if I get the newer Comfort Belt, no more HR Training for me. Just as well, I want to go by feel anyway.
