We ran today at the Waterfall Glen trail near the Argonne National Laboratory. The temperature was near 60 - unbelievable for November 26 in Chicago.
It's a crushed gravel multi-use trail, so there were runners, walkers, mountain bikers, and horses on the path. My plan was to try to run 7 miles, the most I'd run since Portland, the morning of the day I hurt my knee. I also planned to use a R4/W2 interval.
And I am VERY pleased to report that it worked. Somehow I even managed to maintain a sub-13 minute pace. This makes Miami or Disney Half Marathons [or BOTH] a possibility.
ORN: 7 miles, 1 hour, 29 minutes, R4/W2 for a 12:45 pace.
