I dig my regular Riverside Park running route, but it's bad for telling how fast I'm running. The lights throw me off, and I'm not even sure of the exact distance. Central Park is a great way to tell pace because it has set mileage. My post-marathon plan has been relatively short runs (5 miles) at a pretty good pace. Tonight, I went to Central Park to see how fast I'm going. Because I have to run to the park, I only got an accurate read during the four-mile loop: 28:24, about 7:06 per mile. Not so bad. Of course, to run a 2:59 marathon, I'd need to run over 15 seconds faster per mile for 22 extra miles. Whatever. It's early.
