Cheating would have been easy, and its best to remove the possibility - I'm pretty sure I lost 2 places in the first time through the switchbacks and no one overtook me there. Must admit it was tempting, especially the state I was in, as I was going for a good for age time and wasn't too bothered otherwise (just have to go for a charity place now , good for the sole I suppose ) - mind you I would have won a prize then (were there prizes) and I couldn't have lived with myself for that, one thing cheating yourself another thing cheating others
To avoid some of the possibility of cheating having a timing mat at each lap would have been good and no switch backs. It was difficult to judge where you were supposed to be on the road, must admit I just keep as close to the inside as possible.
And Shrek, you are absolutely correct its the course that was at issue, though a little curtesy leaving some room from some of the larger groups going 3 abreast would have been nice.
Mile markers were terrible as previously stated, in that lost seemed to be missing, I thought they were reasonably accurate though.
On the plus side, everyone was really nice, marshalls, hotel etc, lots of support during the race an sympathy for my limping sorry carcas afterwards. Great to have bottles of water, but you could tell they were going to run out, people at the beginning just grabing a mouthful then chucking it, pretty wasteful but there was no choice, I can see why most events use cups (hopeless for me, I just spill down my front). I'd suggest smaller bottles next time.
I hope they do it again, it could be a great event, the elements are there. Thoughts a bit of a treck for me so probably wouldn't be back.
