I also ran for the first of October. It's a gray, drizzly day and the 50 mile ride I was supposed to lead up to Hollis, NH, well, I cancelled it. It was pouring this morning.
I ran 5K, and ran almost the whole way. Took 3 maybe one minute walk breaks, but I did run up one small hill that almost always makes me want to walk. It's right at the inside curve on a somewhat busy country road, and I was too lazy to cross the street. But, no cars came and I flew up that. I did manage to run up the big hill, but I must have been going like 3 mph. Made myself stretch, too when I got back. Some days I just know I will feel OK running. As per my running program, I have no idea how fast I went or how long it took. Didn't even look at the time.
