Went for an 8 mile run tonight, and for the first time in 3 years of running I did a negative split. Usually, no matter how far I run, or how slow the first half of my run is, I always finish the second half slower than the first. But today, I did the second 4 miles quicker than the first. I ran the first 4 miles in 28:12 and the second in 27:30 It wasn't a flat out pace, obviously, but I was glad to discover that I can run a negative split. I thought it was beyond me. I even managed to throw in a 6:15 mile at the end. Bizarre thing is, I found the first 4 miles a lot harder than the second. My legs felt heavy and I was really just plodding along. Then after 4 miles I just felt great. Still wasn't pushing particualrly hard but just felt I was floating back. Anyway, I feel very good right now.
