Run an ultra marathon for charity

Ultra marathons are any run longer than a marathon (26.2 miles or 42.2 km) - the most common distances are 50K, 100K and 100 miles. Despite this, distance is not always the key challenge with ultra runs - the total ascent gives a much better indication of how hard it will be. Select a specific distance, your location for ultra runs in your area or scroll down to browse events.

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.
