RunThrough Trails Ascona-Locarno
2025 marked a milestone year for RunThrough Trails as it expanded beyond the UK to host its first events across Europe. Having already established itself as a leading organiser of trail running events in the UK as an offshoot of the parent brand RunThrough, which delivers over 300 events annually for more than 400,000 participants, this move represented a major step in the brand’s global growth. Driven by a passion to create unforgettable experiences in some of Europe’s most iconic trail running destinations and to inspire people to RUN INSPIRED, RunThrough Trails successfully brought its renowned event expertise to the continent with outstanding results.
“From Girona to Morzine and across to Interlaken, our first European season has been a joy to deliver and a privilege to share with so many runners,” said James Tilley, RunThrough Trails Director. “Ascona-Locarno is the perfect finale. I am incredibly proud of our team, our partners, and our volunteers for making this year so special, and I cannot wait to see the season crowned off in Ticino.”
Starting at Largo Franco Zorzi in the heart of Locarno, RunThrough Trails Ascona-Locarno invites runners to choose from 24k, 42k, and a family-friendly 1.5k. The route begins in the city centre and sweeps through the iconic Piazza Grande before tracing the river toward the mountains. Lush, green trails with panoramic viewpoints along the way and a memorable climb to Pizzo Leone that tops out at over 1,600 metres. After conquering the climbs and the descents back toward town, participants return to a warm Swiss-Italian welcome and a vibrant atmosphere of cafés and restaurants along the lakeside.
Ascona-Locarno is the final European RunThrough Trails event in 2025 and marks the close of our first year of racing on the continent. Launching in Europe has brought thousands of runners together on new terrain and in new communities, and the response has been inspiring. This finale in Ticino brings the curtain down on a season that has blended natural beauty, thoughtful course design, and the hospitality of our host destinations.
Volunteer support remains central to a great race day. We are grateful to Swiss Volunteers for their help in recruiting and coordinating the dedicated team that makes the event possible. We also extend our thanks to Ascona-Locarno Tourism for their local support and partnership in showcasing this remarkable destination.
