My 3 mates I ran with all walked some of it pay but all finished 5-10 mins ahead of me. I'm worried I won't be able to run 26 miles which is the sort of thing I'll hate - I want to try and run it all but just don't know if I will be able to. Loads of walkers for parts today - my pace was barely above walking pace last 3 - I'd have been better walking a few mins then running for 5 etc I'm sure but I'm too stubborn!! I guess it's a marathon and it's about the distance so if you do have to walk a bit cest la vie...?!
I did my 50th marathon two weeks ago, have never not walked at least a bit of one. No shame at all in walking.......there are several run/walk programmes that start faster than 3.30 pace. Chill out !
