BigSea Trails (WATER)

Immerse yourself in the stunning Isle of Purbeck, Dorset, for BigSea—the second race in our Classic Element Trail Series. This trail run offers an array of routes that cater to runners seeking adventure and breathtaking scenery.
The 54KM Ultra route takes you on a journey through some of the most iconic landscapes along the coast and inland hills of Dorset. Starting and finishing on Knoll Beach (Studland), this challenging course features rugged terrain, offering panoramic views at every turn. You'll encounter the Purbeck Hills, where steep ascents and descents await; Corfe Castle with its historic charm; Kimmeridge Bay's dramatic cliffs; Chapman’s Pool’s serene beauty; Dancing Ledge's unique rock formations; Durlston Castle's grandeur; and Old Harry Rocks' striking chalk stacks. This route is designed for experienced trail runners looking to push their limits.
The 18-Mile Challenge, a slightly shorter but equally scenic option, still captures the essence of BigSea’s coastal beauty. With its single-loop design, this course takes you through much of what makes Dorset so special—rolling hills, historic sites like Corfe Castle, and stunning coastlines such as Kimmeridge Bay.
For those who prefer a full marathon distance but want to experience something different from the usual road race, BigSea offers an All-New Marathon (26.2M) route that combines the best of both worlds: challenging trails with breathtaking views at every step. This course showcases some of Dorset’s most iconic landmarks while providing runners with varied terrain and elevation changes.
The Half Marathon (13.1M), a shorter yet no less impressive option, allows participants to experience BigSea's unique blend of coastal beauty and inland charm in half the distance. It offers a taste of what makes this event so special—spectacular views, challenging climbs, and historic sites like Corfe Castle.
BigSea is part of our Classic Element Trail Series, which celebrates the raw power of nature through four extraordinary events: Earth, Water, Fire, and Air. Each race in the series challenges runners to engage with different elements, from conquering muddy hills and rain-soaked valleys (Earth) to racing beneath vast open skies (Air). Inspired by water’s fluidity and strength, BigSea invites you to embrace Dorset's rugged coastline and inland trails.
Join us for an unforgettable trail running experience that will challenge your limits while inspiring awe at the natural beauty of Purbeck.
