Well it was supposed to be 7.5, but I felt so good at that point that I decided to do 10, miscalculated and did 11! My app got seriously confused by all that but I think it took me about 1hr10 to cover the 10k.
At 2k I felt awful, at 7.5 I felt fantastic and at 11 I felt like another 5 would have been no trouble. I think I get how people end up running silly distances.
I couldn't have done it without the ever blessed Laura, I started the c25k at the start of October and I remember how worried I was when she said it was time to run for three whole minutes!
