In short: Be prepared... In full: This is impeccably organised with lots of friendly marshals, beautiful scenery and strong support en route. The buses out from the park and ride and back from the finish worked as advertised.
But it is hard - not much steep but not much flat either. It was my poor choice of first marathon but on a hot day I was an hour over predicted pace based on a recent road HM. Even experienced marathoners were walking from 20 - 21 onwards. There were a lot of guys with finisher T-shirts from big ultras including several from UTMB and a lot of obviously military as well - these guys had well practiced nutrition strategies and ultra-type kit. If you are used to flat road races, give this the respect it deserves, plan to be out there for a long time and take the first half slowly - basically treat it like an ultra and you'll have a great time.
