Well, I did run Sunday AM at a local school track, and I also ran today, Tuesday, in the work gym on the (blah) treadmill. The limitation on my running at the moment is my legs and feet; I felt fine in terms of cardio, but my legs are hurting and I don't want my plantar fasciitis to flare up. I consulted with Marathon Michelle, a running colleague at work and former member of the Jersey City Fight Club. She says; 1) get really good running shoes, the right ones for YOU (as fellow martial arts blogger Sue C suggested); 2) start with short distances; 3) increase no more than 10% per week.
The good things about running: 1) you pack in more cardio training and calorie burning per minute than lots of other cross training; 2) I really like how much stronger my legs feel afterwards, even though they hurt. Running outside can be interesting; at work, at least there are TVs near the treadmill. And I can't really keep my BlackBerry on call while I'm running, so it's a real, true break from work.
It would be awesome if I could consistently run as cross training for my martial arts, and my feet and legs stayed healthy. Fingers crossed. At some point I will consider whether one of my three days a week of running should be interval sprints, but first I want to just get aerobic running down.
Tomorrow night, back to grappling class.
