Is this the toughest half in the UK!? Proper, fair kit check. Well marked route if you are paying attention and have downloaded the gpx as well! Took me an hour longer than a road half marathon. Peter Lester-Owen

Orientation! A definite need to be able to read a map, we found it very easy to lose the Offa's Dyke path in parts.Those tough climbs reward you with some amazing views, simply beautiful. Lindsey Black

Amazing route and well organised. Kit check at the start - safety was taken seriouslyElectronic check in at checkpoints made things seamless. Amazing route. James Hurrell

Well organised race. Great to have transport back. Great facilities at the start. Andrew Gooda

Great route, friendly event. Anon

Top event. Nathan S

Tough old route. Chris R

Muddy and boggy and ups and down and rain and wind distance made this trail so hard but so enjoyable. Even if it was a sunny day the trail alone is very clever and has great inclines and declines and terrains to keep the mind entertained. Chris R

Loved It. Michael S

Route is fantastic and well marked however glad I had the GPX file downloaded as needed it as I got towards Bodfari. Michael S

Amazing route, very challenging but worth it! Reiss A

Really good climbs, views, fun. Really enjoyable way to spend a Sunday. Teleri W

4 steps to wellbeing
Sleep well

A good night's sleep is an essential foundation for a healthy lifestyle, effective training and weight control.

Train slow

Low-intensity training is easier for you, reduces the risk of injury and helps builds an efficient aerobic system.

Eat natural

Cut out sugar & junk food, reduce carbs, eat natural foods and train your body to burn fat for fuel.

Get outdoors

Fresh air, natural light and reconnecting with nature all help to improve mental and physical wellbeing.
