I've been reading (shocker) 10,000 blogs and Web sites about marathons. One of them suggested making sure you do lunges to strenghen your thighs. So, yesterday, which was my walk/xtrain day, I walked 30 minutes, and did the 10 lunges (of death).
Today, I ran 4 miles, accidentally erasing my split times (marathon training, as one of my running buddies so trenchantly said, is a misnomer: it's actually watch training, as in how to CORRECTLY use the various features on my IRONMAN watch). Anyway, I thought I was doing a decent pace, a little lunge butt twitch here and there, but nothing bad, until I stopped, stretched, and hobbled into work, where I am now sitting on a hot towel.
Warning: Lunge Butt is nothing to laugh at.
