There are two UK races, the Round Rotherham and the Norfolk coast ultra, but both are 1 week apart in Mid-October, which clashes with my usual autumn road marathon.
Belves, UTMB (France), Chiemgauer, Stunt (Germany), Taby (Sweden) appear to be the only European qualifiers and I wondered if anybody had tackled these (clearly lots of people will have done UTMB but I was looking for something a bit more sign-up-and-go).
Chiemgauer looks like quite a good race although it's the same weekend as the Lakeland 100 which is irritating.
