Course Description

The Castle Trail 30km follows the spectacular second half of the Three Castles 50km course, taking runners on a beautiful riverside journey through the heart of Kent.

Starting at Little Fant Farm in East Farleigh, the route quickly reaches the River Medway before crossing the historic East Farleigh Bridge, one of the oldest surviving stone bridges in Kent.

From here, you'll follow peaceful riverside trails through Teston Country Park, Wateringbury and Yalding, passing picturesque locks, open countryside and some of the county's most scenic landscapes.

After reaching the Hop Farm and your second checkpoint, the route continues alongside the River Medway towards Tonbridge, where views of the magnificent Tonbridge Castle signal the final few kilometres.

One last push takes you onto the Tonbridge athletics track, where you'll complete a full lap before crossing the finish line to an unforgettable welcome from spectators, volunteers and fellow runners.

Fast, scenic and incredibly runnable, it's the perfect introduction to longer-distance trail running.
