I had a pretty decent run yesterday and thanks to my buddy Rob T. and letting me borrow his old ANT belt, I had better readings using my Suunto t6. The old belt I had I found had cracks in it, which would explain the erratic readings from before. I still need to work more on keeping my HR in check, but I was able to stay in my low-intensity aerobic zone (below 138 bpm) for 40+ minutes out of a solid 47 minutes. Most of the increases in HR were around 1-3 beats above 138 bpm, which is a good thing...but it could be better. So in 3.2 miles, I'm able to run about 47 minutes. Based on this, I can potentially finish tomorrow's Dizzy Daze run in about 7.5 hours if I run/walk the 50k distance and keep my HR completely within my fat-burning zone. However, I could also do everything in 6.5+ hours if I opt to stop at the marathon point. I guess I'll just have to see how much I'm up for it. I really only need to do enough to get my endocrine system to respond appropriately in time for the Mt Si Ultra (doing the 50 miler again).
Then again, I could just run the first 6-7 loops in my low intensity and then run the last 2 loops at a harder pace to finish sooner and see how the EPOC looks afterwards. I'm sure I'll figure it out by tomorrow morning.
