Didn't have it today. Felt very good at the beginning and wanted to run 7:15-7:20 pace. Check. Just couldn't hold it. I've overestimated my ability I think, can't blame the heat, it wasn't that bad. Especially disappointed in my willingness to suck it up around mile 6-7. My legs just wouldn't move. Live and learn. At least I can throw the BQ out the window and focus on 3:30 at Chicago.
