I'm currently toying between Hilton and Belaire. Love the belaire but next year will be my first time having to get there from the US rather than good old LHR so the added convenience of the Hilton is a big draw.
S.Snail. Regarding marathons in the build up. Everyone here will probably have a different set of advice. Personally I've done up to 8 marathons/ Ultras (Jan-May) and as little as 2. My times for the two Comrades at either extreme were within 5 seconds of each other. So i will be sticking with less for next year.
