As an increasingly feeble ex-jock, hill repeats and roadwork are the last activities that keepsfrom falling entirely into the abyss of old age. One of these days I'm going to have a ****ing heart attack at the top of the stairs I run...
At my best, I'd do something similar for about 10 miles in the morning. Then, after my morning workout, I'd do some swimming, and then try to throw a lot of punches in the evening workout.
Do it for 6 weeks, and I never felt tired in a fight. I can attest to the pain and the discipline that takes, though, and as I got older, it's the running that I abandoned, and I replaced it with more "sprints" and swimming and weightlifting.
I got bigger, and my stamina tanked. I do NOT think that is a coincidence.
