Two serving Coastguards will face mountainous terrain, snow, ice, and a punishing time target as they tackle the brutal Fan Dance, a 24km weighted route March made famous as an SAS selection test. They’ll do all of this whilst carrying in excess of 35lb of equipment.

The challenge begins as soon as the race does with an immediate ascent of Pen y Fan

which is 2,907 feet (886 m). The route then descends on the other side of the peak with a pathed route to the halfway point before turning around and reversing the route. The return leg provides an even tougher challenge with the evil ascent back up the Fan known as Jacob's Ladder.
