I cut my running way down, from an average of 50+ mpw over many years to an average of under 10 per week. Almost all of my running now is at a hard effort. Basically, in the 25 years or so that I was a distance runner, I fought my weight every minute of every day. Now that I don't run much, and I lift and do interval work, it's a lot easier to drop the weight. It doesn't help me with racing though. I've run a couple races this year and didn't do too well, but I don't really care anymore either. No more 100 milers for me, most likely.
