JMC - I have done both races for the last 3 years. Obviously these are December then Jan times;
first time;
S10 57:33 4vills 77:23
S10 59:33 4vills 77:00 (was getting over a virus for the S10)
S10 58:11 4vills 76:05
I honestly think I could have gone close to sub 75 last year, but it was v v windy.
I do think knowing the course is a bit of a help on the 4 vills.
