Notes
Parked at WWS and ran 2 miles to meet up with group in Warrenville. We wound up going a 13+ mile loop west on the Batavia spur and back through Fermilab which must have repaved the paths since last time I ran there as they were perfectly smooth and great. I was feeling good and pushing the pace at points. Lots of stopping with some construction on the way out and then a long break at the Fermilab center where I got a little water, then another long break at the group endpoint back in Warrenville before I ran the last 2 back to WWS and a little to make it 17.5. HRM was good the majority of the time but took a couple of miles to kick in then would show incorrect low readings for various points, maybe the strap battery is low, annoying.
