The Maverick Chilterns Trail 2027
Saturday 24 July 2027 | Princes Risborough School
Step up to the challenge of the Maverick Race Chilterns Trail, an unforgettable journey through the breathtaking Chiltern Hills. Starting from the vibrant market town of Princes Risborough, just an hour from London, with direct rail links from London Marylebone. The route will take you deep into one of England’s most picturesque and historic landscapes.
The route winds across ancient beech woodlands, sweeping ridgelines, and hidden valleys, revealing far-reaching views across the Buckinghamshire and Oxfordshire countryside. Don’t be fooled by the rolling beauty—the Chilterns are packed with punchy climbs, chalky trails, and technical woodland singletrack that will test your strength and stamina.
Carefully crafted to showcase the best of this Area of Outstanding Natural Beauty, the 50km course links sections of the legendary Ridgeway and Chiltern Way, weaving through quaint villages, quiet bridleways, and wildlife-rich chalk downs. Expect a trail that’s fast in places, technical in others, and always rewarding.
Not ready for the ultra just yet? As with all Maverick Race events, we’ve got you covered with a range of distances, so whether you’re chasing a personal best or embracing the adventure of your first trail race, the Maverick Chilterns delivers big-sky scenery, well-marked trails, and the unmistakable Maverick spirit. From the first climb out of Princes Risborough to the final descent back to the finish, this is a race that celebrates everything we love about trail running—challenging, beautiful, and proudly untamed.
This is not a dog friendly event, dogs are not allowed at the venue because it is a school.
