Hi Loula 
Mmmm, I'm so very, very tempted... but am waiting to see how my marathon goes in October. And then I'm kind of stuck on the IM tri next year. Can't really see beyond that at the moment.
Can anyone tell me how long it takes to recover from an Ultra? And do folk run the whole way. Or do a run/walk combination?
Really do like the idea of Hadrians wall....
Oh, so much to do... and if I plan one big event each year it's going to take me a long time to do all these fun things!
