Since I don't have a gps watch, I've been using WalkJogRun to find running routes and figure out how many miles I've run. The other day I thought I ran 10 miles in an hour and 15 mins. I was like "wow--it looks like training for the marathon is going to be pretty easy". Well after I walkjogrun my route I found out it was only 8 miles. A little disappointing especially since I was hobbling all that day.
