Yes - I'm doing it 
So - it's an early start on Saturday - coaches from the finish at 05:45! Hopefully it's a little less challenging underfoot than the MCN Brecon 40 in December.
I'm using it as a training run for Fellsman and then onto my first 100-miler in August, (NDW100) so won't be breaking any speed records - probably somewhere around 10.5 - 11.5 hours for me.
Good luck, here's hoping the weather is good!
