Thats right, last year I put down 4 to 4:30hrs and was placed in zone 3, this year 3:30 to 4hrs and I am in zone 2. I think they had a couple of staff at the entrance to each zone glancing at numbers, however once inside the zones alot of male runners where jumping the railings on the opposite side to pee in the trees then jumping back into their zones, no one seemed to be checking if they switched zones when they jumped back over from the other side.
My autistic son is on beta blockers after a nervous breakdown a year ago, he also developed severe Ocd too because of it, he is on a high dose, but I remember him falling to sleep a lot when he started the beta blockers but he doesn't anymore now that he is used to them.
Last 18-20 mile long run planned for next Thurs then taper time, Zone 2 for me this year, Really enjoyed the training this time around, love the crowd support at this event and the resident high fiving vicar! Hope there's a free beer at the end again.
Another vote for injinji toe socks, I used to swear by x socks until the same thing happened to me at mile 13 in the yorkshire marathon last year and suffered the second half for it. The injini's are indeed awesome and you won't regret it.
