Long, slow back workout.
Wide grip lat pulldowns, narrow grip lat pulldowns, dual-axis machine pulldown, seated row, one-arm cable pulls, straight arm cable pushdowns. All 6-up/6-down.
The worst thing about this (aside from the counting. You're counting the down count, the up count, and then the rep count. It's very easy to lose track!) is that when you get to the point where you're dying and tell yourself "only 3 more reps", and you realize that's still over 30 seconds worth of reps.
Tomorrow running easy 6 to replace what was going to be 4-mile tempo run with 1-mile warm-up/cooldown. No foot pain yesterday or today.
