I did my speedwork tonight, although not exactly according to plan.
I ended up doing 4 x 1 mile at 9:50 pace, w/ 1/8 mile recovery between intervals. I have not been that red in the face since (insert embarrassing story here). I started feeling a little tightness in my left adductor again, partway through the 4th mile, so finished that one up, and then did a 10 minute cooldown. Overall, 6 miles total run, although only 4 of it was fast.
I've added 100 abs and 25 pushups back into my post-run routine (after the always necessary stretching).
I'll do some easy miles tomorrow (well, tonight I guess, since it's now past midnight).
