Did Bristol last year. Its a great course, nice and flat, was hoping to get in under 2 hrs but ended up 2.02 but was happy as it was only my 2nd HM. Did Anglesey Race in march in 1:58 and that is definitely not flat. So hoping to come and do Bristol again in sept and aiming for about 1:50. Best of luck with the training.
I used to experience severe hip pain on the right side after running about 10 miles. Absolutely nothing I could do but walk slowly to the finish. I did some research and found it could have been IT bands. Always do a stretch routine before running now and its never come back.
