The Durham Coastal Marathon is an immersive adventure winding along the rugged cliffs and charming seaside stretches of Seaham, County Durham. Covering 26.2 miles with an elevation gain of approximately 1,200 feet, this route tests stamina and focus while revealing the raw energy of the North East coast.

The trail begins along Seaham’s expansive pebble beach where the relentless North Sea chips at the shore, daring every runner and hiker to match its pace. The terrain is a blend of compacted coastal paths, grassy bluff tops, and occasional rocky patches – straightforward but demanding enough to keep you sharp. Expect variable footing, where well-worn trails soften before snapping back with sudden climbs.

As you push forward, the cliffs open to sweeping views of the Atlantic horizon scorched by salt spray, and inland, shaded pockets of woodland punctuate the route with fresh, earthy scents. The path snuggles close to ancient headlands, with gulls circling overhead like watchful guides. Small rivulets course through naturally carved channels, inviting moments of cool respite.

Beyond the physicality, the marathon tracks through the history of this coastal town—stone ruins and remnants of old fishing settlements lean quietly into the landscape, grounding the journey in local culture. Battersea Point and Cold Hesleden represent lesser-known outcrops where the ocean’s voice softens, almost listening.

Preparation is key here: hydration stations are sparse, so carrying your own water is essential. Suitable trail runners with a good grip will handle the fluctuating terrain best. Starting early avoids the afternoon coastal winds that can rise suddenly, bringing a chill even in summer. Timing your pace to match the terrain’s rhythm—steady climbs and push-offs from flat ribbon paths—keeps energy in reserve.

Midway, the path threads through a stretch of quiet woodland that resists the sea’s roar, where sunlight dapples through leaves, offering comfort and shade. As you approach the finish near the quaint Seaham marina, the undulating course eases, paving the way for a satisfying final push.

Durham Coastal Marathon is not just a race against the clock; it’s a measured engagement with this fiercely independent coastline. The scenery does not yield willingly but demands respect for its presence and power. A practical mindset, solid gear, and steady anticipation turn this challenge into an experience that balances grit with exhilaration.
