In short: Nice scenic course. About half of it on the aerodrome so traffic. Needs work to make it a better marathon training event. In full: The first running of this event, it was decently organised with plenty of parking. They delayed the start as the sorted the baggage room delays, but sort it they did and quickly. Half the course was on mostly more minor Surrey roads which are narrow and have some less considerate drivers. The other half on the aerodrome so plenty of space and traffic free, if a bit exposed to the wind. Well marshalled with friendly water stops.
Two complaints: mile markers were all over the place, especially miles 4, 5, 6 and 7 of the loop (done twice, so at least you could compare the speed on each circuit). Irritating if like me you were mixing marathon and steady pace miles as a training session for London. I could be as much as 50 seconds too fast on one mile and a similar amount too slow on the next, though I am confident my pace was barely changing despite the wind and the odd short hill. I was never quite sure what my real pace was and do not have a Garmin.
Second complaint that water and fuel stops could have been improved with bottles rather than cups. Fuel especially was promised but given in small mouthfuls at the bottom of a plastic cup, and only at miles 5 and 15. It did not quite add up to one gel. I wished I had taken my own. Plenty of jelly babies if that is what you prefer. Date of review: March 15, 2010
