I struggled for the first 4 or 5 days, then hit my stride after 6 or 7 and felt really strong at, yeah, about day 8 and really surprised myself from there on, especially, for some reason late in the day. After VVR, I got this energy burst about 5:00 every day and found myself able to crank out 3 or 4 really fast miles, up hill, to set up for the next pass, pretty consistently.
