I was a few minutes off my target time, the first two KM’s were slow out of the blocks and then the hills played a part, but what a great race, I enjoyed it so much. Matt Telfer-Maleary, 2024

Massive shout out to the volunteers, cadets, medics, members of the public etc etc, so supportive all the way round. I will definitely be back in 2025. Emma Telfer-Maleary ❀️ 2024

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.
