The organiser of an endurance event in the Brecon Beacons has told BBC Wales that safety precautions are in place as the hot weather continues.
Around 350 people are signed up for the "Fan Dance," a 24 km (15m)-trek over Pen y Fan.
Last weekend two reservists died in the Beacons while taking part in a SAS selection event.
Ken Jones explained why they decided to go ahead with this weekend's event.
