Along with the pleathora of "best of" threads. What is the dumbest thing you've done in the days leading up to a race. I think I just did mine, switched to a new pair of Zoom Elites(been using them for several months). Decided to do a twenty miler in them, yeah pretty stupid. Now about to lose the toenail on my big toe. Gosh, after 20 plus years of running you would think I would be wiser than that. Live and learn
