Seeing as pre-entry to races seems to be a hot topic at the moment...
Thought i'd mention that I spotted the 2018 Montane Cheviot Goat Ultra pre-entry opens at 8:30am on 2nd March.
haven't seen any confirmation of race date yet, but I think last year it was the first Saturday in December with a start time of something like 5:30am.
I think it may be quite popular as it seemed to go down well in 2017. I'm certainly going to throw my hat into the ring on this one. Looks tough.
