Event overview

It’s a day of moving around wonderful woodland for all abilities, speeds and experiences. Whether you’re an experienced ultra runner keen to get an early season 50 km in or a newbie trail runner looking to do their first 10K TrailFest is for you! We’ve got 4 distances for you to chose from 10K, half marathon, marathon and 50 km. A distance to suit everyone! The idea of the day is to bring everyone together and to experience the fun of trail running across an amazing estate. Being around others doing what seems impossible can often make it seem a lot more possible too!! If you want to come and run your personal best or bimble about with your mates we’ve got the perfect distance for you. We’ve got vey generous cut off times too, to try and remove some of those barriers to new people trying out the sport.

This event is part of TrailFest - Holdenby House.

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.
