I've gotten a bit reacquainted with it myself the past two days. Yesterday's repeats were fine by split time, but the legs definitely lacked any snap. Today I headed out for an easy longer run and felt the same way. The adductors were a touch sore from trying to bring the legs through quickly yesterday, and in general the legs just didn't have any drive. I didn't push the pace at all, but instead just focused on getting the time in.
Two days of dead legs is a bit of a warning sign, so tomorrow's goal will be running easy enough to be ready for a pace workout on Friday. If the legs don't feel like they're coming back during the first five miles or so I'll cut things short, which might not be a bad idea considering I'm scheduled to work on Haiden's school's irrigation system at 7:15am.
I certainly don't feel like I'm teetering on the edge of a breakdown from the training, but what Mystery Coach says about staying ahead of the recovery curve is occupying my mind.
Training: am., 16 miles, 1h51m, 6:58 pace
pm., 6.2 miles easy around 7 minute pace
