60th birthday in less than 3 weeks, was planning on doing this then but what a Day!!!! Sunny, upper 50's when started, got to about mid 60's was planning on doing a metric C, but at mile 50 I was averaging 15.1 so i decided to go for it. Did 102 total, 100 was 6:47. Lots of hills and the WIND was 10 mph steady NNE. I'll take the hills over the wind. No flats, no near misses, folks were friendly, Life is Good.
I think I gained weight, 60 fluid oz. water + 20 Oz Gatoraid (hate that stuff) + 20 Oz Coffee (12 + 8) plus 1 plain hamburger, 2 big cookies, plus 2 small candy bars. Plus a Beer while relaxing in the tub.
HR max=172 , avg=139, zone (139-170)=4:52, calories burned = 5,773 according to my polar F6.
Again, Ain't life Grand. Puts me at 992.8 miles for the year.
This is my 4th Century. I'll try a metric on my birthday. :) :)
