Thanks. The actual website doesn't say anything about it being ER. In fact I'm a bit cheered to see that the only info about it is the price, what time to turn up and where. None of this £35 by PayPal, tshirt, goody bag, and medal stuff.
I've done the LDWA 28mile south downs marathon a couple of times, the Rutland water marathon in November (trail and serious wind chil) and I'm heading over to the Brecons this weekend and will do some more solo running in the hills. I've spent many days winter walking up on Kinder I'd love to run up there. Looks like a good one.
