Today was my last regular training run, and for the next two weeks, I'll be tapering to race day on August 19. I think that I'll use a "binary" taper in which each week is half of the preceding week.
During the past 3 or 4 weeks, I've been pushing my speed as a low-level form of speed training, and I'm looking forward to two weeks of reduced intensity and distance. I can tell my body needs some additional rest. I've had a good month of training. I've gotten used to the 13 miles, and I've significantly decreased my average pace. The two weeks of shorter rest runs will allow my body to recover, and I'll hopefully peak on August 19.
