In July, the Canton of Valais invites runners to experience the charm of Sion, Switzerland's oldest city. Nestled amidst snow-capped mountains and rich history, this quaint town offers an ideal setting for two running events that kick off a weekend packed with festivities including Swiss National Day celebrations. The races are held on flat and paved courses, measuring 5 km and 10 km respectively, making them perfect for runners looking to clock personal bests without the worry of elevation changes. The route is affectionately known as "Loop of the Sédunois Bridges" due to its seven bridges and walkways that crisscross over the Rhône River. As you run along the banks of the river, you'll pass through downtown Sion's historic streets before looping back for a second lap. With the start time set at 7 PM, runners might find themselves finishing under the night sky, offering unique views of this ancient city after dark. The atmosphere is vibrant with tourists and athletes converging to celebrate the weekend’s events. After crossing the finish line, you'll receive your medal as a testament to your achievement and be ready for further exploration in Sion. The town boasts two castles—Valère and Tourbillon—that stand out against the backdrop of towering mountains. For those traveling with families, there are plenty of activities nearby, such as strolling through Bramois’s natural orchards or exploring the medieval village of Saillon. These options provide a great way to unwind after the race while enjoying the scenic beauty that surrounds Sion. Join us in Valais at the end of July for an unforgettable running experience and immerse yourself in the rich history and stunning landscapes this region has to offer. The event promises not only competitive racing but also cultural immersion, making it a unique opportunity to connect with both nature and heritage.
