The Waterford Greenway Marathon offers a 42.195km challenge set along one of Ireland’s most striking converted rail trails. This route stretches from the historic town of Dungarvan westward toward Waterford city, threading through a landscape that shifts from wooded riverbanks to open coastline, all punctuated by the occasional old stone viaduct arching over the valley below. Elevation gain is moderate—roughly 300 meters overall—but the steadiness of the incline and well-maintained crushed limestone trail makes it accessible to a broad range of walkers and runners.

Begin your journey early to take advantage of cool morning air. As you move along the trail, the River Brickey dares you with its energetic flow, pushing the route alongside its banks, while the surrounding forestry stands firm and quiet, occasionally releasing bursts of bird song. The terrain is mostly flat with gentle rises, avoiding harsh climbs but keeping muscles engaged over sustained distances.

The trail’s surface is firm and even, ideal for sturdy hiking shoes or trail runners—footwear that breathes yet grips is essential to avoid slips, especially near stretches where dew can settle or after rain. Hydration resources are limited, with only a few small villages en route, so carrying at least 1.5 to 2 liters of water ensures steady energy and well-being. Timing your pace to match daylight and weather conditions is critical; late summer mornings or early autumn days provide the best mix of temperate weather and fewer crowds.

The experience balances nature’s rawness with human traces: abandoned stations, stone bridges, and tunnels that beckon you forward. This is a route that respects its own history, inviting adventurers to engage rather than rush. The environment will challenge your stamina and focus, offering moments to catch your breath alongside sweeping sea views or the quiet determination of hedgerows that mark the walk’s edges.

Finish the marathon in Dungarvan, a town eager to welcome tired yet accomplished travelers. Its vibrant local culture and fresh catch seafood provide perfect rewards. Whether you complete this route as a runner, hiker, or in segments, understanding the practical demands alongside its quiet beauty will help you meet this trail on equal footing with its fierce but inviting character.
