Went to the gym for usual workout, and ran from my office to there. This time I swapped out the orthotics I got with my running shoes for the ones that just came with the shoes, and rather shockingly I got zero knee pain. Nada. Nothing. I also ran faster than normal. I hope this is the problem! Back to running every other day I guess.
Tomorrow I plan for a quick moody and back VO2max style workout. If I get up early enough. Abductors are still sore from monday's workout!
