This morning I had a great 20-mile run of which 19 were along the Rock Creek and the Potomac, all the way to the Roosevelt memorial and back. I was able to enjoy the fall scenery and the cooler air. This is my last long run before the Marine Corps marathon on the 30th of this month. I ran it at an even pace and was able to finish in a decent time (3.25 hours) in spite of running uphill and against a stiff wind most of the way back. My legs don’t feel as much pain or stiffness as they normally do, so I am feeling reasonable good about the marathon.
On Thursday morning I ran on the track at Howard before getting to work. For the first time I did interval training. Runners’ World magazine had something called Yasso, named after one of their own writers. Apparently he had found that if you can run ten 800-meter runs with 400 meters of jogging in between them then the average time of those 800-meter runs would be the number of hours you can expect to take to finish the marathon.
