The old red phone box marks the race start point where generations of Special Forces candidates line up in the early morning mist to tackle the Fan. Be prepared to go straight at it from the off… The lower slopes are brutally steep and will put you straight into the red.
Look out for the tent at the top of Pen y Fan which serves as RV/checkpoint number 1 and 3.
Approach to checkpoint/ RV2 and turnaround point. Don't forget to check your race number in and grab a warm brew.
Going back up the Fan via Jacob's ladder, for many the hardest part of the course.
The penultimate RV is a revisit of RV1, remember to go through the RV procedure and log in with checkpoint staff.
Going back down, make sure you follow the trail contouring the side of Corn Du to save unnecessary climbing.
