Looks like it's the last John o Gaunt Challenge (W Yorks LDWA) in and around Washburn Valley on 19 Oct, with a new event in Gargrave area being mooted for next year. JoG doesn't get many runners but I'll be giving the 20 mile route a go.

Just found this for the 20 mile route:

The 25 includes a loop around Thruscross reservoir (including the only bit of real moorland on the route).
Entries for the 2014 Valleys 100 opened at midnight - already nearly 100 entries on SI. Should be a good tough event over and around the S. Wales valleys, they are no pushover with plenty of climbing.
If you are thinking about it, I would submit your entry sometime soon.
