Myself, Daf the dog whispered and Martin Rees are putting our feet to the test of 40km. We'll finish it eventually. From my experience in the mountains and at work, Mountain Rescue and Air Ambulance play such a vital role in helping people and they're being used more and more as outdoor activities become increasingly popular. Every penny counts.

I've only set at £100 as this is very much a last minute team. Would be amazing to go way past that.

The WAAT4 Challenge is a prestigious navigation event in Wales’ beautiful Brecon Beacons National Park. Teams from all over the UK take part every year.

Its reputation is growing quickly and it features in the walking calendar for such events. Each year over 500 competitors take part over either 30km (now 20km) or 40km Challenges which includes South Wales’ highest peak - Pen y fan.

The event takes place on Saturday 16th June 2018 to raise money for Brecon Mountain Rescue, Wales Air Ambulance, A Safer Dyfed-Powys and DofE Wales.
