Overenthusiasm leads to rest

Abs, inner thighs, calves are hurting. Even my collarbone, it seems. I feel misaligned. I don't think it's the running itself, but probably exhaustion from combining that with overenthusiasm the last two days in the weight training/core strengthening department. Maybe it was too soon after the Tuesday night class to go into the Wednesday morning class -- not enough rest. And isn't REST my favorite word as far as exercise is concerned? Anyway, I did my pre-work workout yesterday, taking in a core strengthing class and then running a hard 2 mi. I was going to head in again this morning (I am really trying hard to stick to plan) but I was supercranky about these aches when my eyes slowly unglued from slumber. Yes, time to schedule a massage too. Thank you health plan.
