No pacers at London this year anyway. I think they had to agree to all sorts of conditions months ago when planning to ensure they got to run it and pacers was one thing they got rid of (creating clusters of runners?) The bag lorries are gone too which is a bit of a pain as anything you have with you when you travel to the start now either has to come with you on the run or be abandoned.Thanks for the tip mate, I dont really intend on following a pacer at london, but as you probably know yourself its easy to fall into it when your in the race. My main thing is to not go off too fast but not go out too slow!! Not asking much there!!
