I have just run my 3rd half and was really disappointed with my performance of 2hr 15sec. I am really struggling to crack the pacing for the distance and know that I should be able to achieve close to 1hr 50min.
I seem to have got into a cycle of running the first 6 miles in about 48 mins, and then running on empty from about mile 11.
I do 10ks in 50 mins and hope to go sub 50 this year. I do 10 mile races in 1hr 24 mins. In addition to this I am training up for a marathon and have now got my long runs up to 15 miles, and taking about 2hrs 30min.
Some of the problem is probably mental. For example on my last half I was still comfortable with the pace at 6 miles but when I checked my watch, I went into the 'oh no - too fast' attitude and then did mile 7 in 10 mins. managed to pick up the pace but hit real problems again at 11.
I do not have a training/running partner and am not in a club. I have one freind who runs some races with me but she is really fast and competitive and tends to use me to score points off and boost her ego - which probably does not help me. Come to think of it, I do better int he races she does not do!!
Any advice, hints etc gratefully accepted.
