I went out with the grand intentions of doing a 7 mile road run. That would have been 10% more than my previous long run. About 45 minutes into it (about 4.5 miles) I got a cramp in my stomach that had me walking for 5 minutes. I was able to get started again and felt good enough to go down a street that I hadn't been down before. Of course, 15 minutes later I was walking again. feh I walked for 10 minutes and then ran the rest of the way home. Total time: 1:24. I took the car out and clocked the mileage for my run/walk... 7.9 miles! No wonder my legs and back are sore today!
