thanks again for the advice guys. just a point, the club is one of the best known and respected in northern ireland. it is not a small club and has some very well qualified coaches.
I had the half marathon on saturday, a few from my running group (the 2:45ers) were pacing for 1:30 they wanted me to come with them but i got chatting to a slightly slower guy from the club and went with him instead. i finished in 1:40:07 which is about 4 mins off my pb but not bad given my current form. I was happy with that.
we went out drinkiing after, and i had a good chat with them, i have decided not to run with them between now and the marathon (6 weeks). i met two runners who are closer to my ability on saturday so we are going to start a little group of our own for the next while.
my confidence has started to return already, i have just come back from a 10k run which was 4 mins faster than the same route ran a week ago! i think i agree now with you all and the guys from the club that the problems were in my head, i hope that i can start to get over it now and start posting some better times again.
cheers again for the advice!
