The whole purpose for your running and strength training is to get better at A SPORT so why would you not go to practice in that sport? That's kind of like skipping a job interview because you were taking a class to work on your interviewing skills.
Yesterday, Lex Fridman, who is very, very NOT stupid (check out his blog if you don't believe me) posted a comment about running.
Jim and I discussed this at length and I wrote a very long response in the comments section of the blog which somehow did not get saved. I think maybe my computer re-started to install updates while I was off taking pictures of the workout at Results Personal Training (awesome place, by the way). I needed to get some pictures of different exercises for illustrations for "the book" and I may have run out the door without saving. )-:
ANYWAY ... I decided to post his comment and our answers here because I think Lex's point is one that a lot of people raise, which is how to maximize your conditioning without impacting your time on the mat.
Lex said that he had been running the last month and, with two mat sessions a day, he was really feeling it in the last several rounds of randori.
First of all ... if your running is interfering with your randori something is wrong. We don't know you, but we speculated that one of these may be true:
- You are running too soon before practice. Normally we space practices four hours or more apart. For example, when I was competing, I would get up at 5:30 a.m. (I still shudder at the memory), run, go to work, lift weights at noon and then go to judo at 7:00 or 8:00 p.m. If you're in good condition, you should have recovered after a rest of several hours.
- You're doing too much in your running work out. The in-season training program I posted yesterday only includes a two-mile run (3 or 4 if you need to cut weight), three days a week. Three other days of the week, the program includes wind sprints. Personally, I would run six or eight miles some days at lunch but that is certainly not necessary and I know Jim never did that nor Ronda (she hates to run). I love running, and having a sedentary job as an engineer back then, it was nice to get some exercise in the middle of the day and clear my mind. HOWEVER, I never ran those six- or eight-mile runs on the days I had a lot of randori planned for the evening. During the in-season period, when you're doing a lot of randori, you really SHOULDN'T be doing a lot of running or super-hard conditioning. Not knowing you well, we kind of suspect that your problem is that you are running either too much or too hard. You don't need to run a four-minute mile or 40 wind sprints. That's for the out-of-season training.
- Maybe you just recently added running as part of your workout ? In that case, if you aren't used to it, it's just a matter of getting in better condition. Run slower or a shorter distance, say one mile, or fewer sprints. Gradually increase the pace and the distance.
