In short: Friendly but hilly narrow roads and lack of water. In full: The run was well organized, with plenty of friendly marshalls putting up with the rain.
However, there was only one water stop, mile 5 where you were only given an inch of water - nothing on completing the race - which was a big deal for me, as i came to the run with only my car keys, so had to wait till i'd driven 30 mins home for a drink of water.
Although the area looked as though it would be very scenic (hard to tell in the rain) and there were paths avaliable, we only ran along road. The roads were very narrow in places. In particular, on the uphills the cars had to slow right down to pass the runners/on coming cars. This meant you were breathing in loads of exhaust fumes whilst trying to run up a huge hill!! I also got splashed, shoulder high, by a car driving through a puddle next to me... was quite refreshing actually.
Maybe i've been spoilt by other races, but paying a similar amount - £12, i've been given timing chip for the event, plenty of water stops and a goody bag (including drinks, snacks and a medal). On completing this race, all I got was a yellow mug with 'Epsom 10 road race' didn't even say 10 what on it...
Another little pain was that you finished about .5 mile from the start. As i parked my car at the start, it meant i had to walk .5 mile back to my car. Not really a big deal, but i was soaked through and it was hailing, so that was very unpleasent!! Date of review: November 23, 2009
