Half marathons in the canton of Aargau

The 21.1 km is the ideal distance for anyone who wants to step up a level without jumping into a full marathon, and the canton of Aargau offers prime terrain for it 🌿. The banks of the Aare unroll mile after mile of steady running, the shores of Lake Hallwil provide a restful backdrop, and the surrounding hills add a few bumps to keep you on your toes. The villages of Aargau, with their flower-covered fountains and half-timbered houses, give long runs the feel of a leisurely stroll. Runners easily find loops of 10, 15 or 21 km starting from their front door, with no car and no big detour.

No half marathon is yet listed in the Finishers calendar for the canton, which doesn't stop you from preparing on the spot. A plan of eight to twelve weeks is enough to go from 10 km to 21 km, with long weekend runs along the river and faster sessions on the tracks of the city of Aarau. The temperate climate lets you train all year round, with a preference for the cool mornings of spring and autumn 🍂.

To aim for a half marathon in the canton of Aargau, look beyond the cantonal borders. The Sempacherseelauf runs along Lake Sempach on May 1, 2027 and offers several distances, including the half. The Neujahrsmarathon Zürich, on December 30, 2026, lets you end the year with a 21 km amid the festivities and possible snow 🏃. More ideas are waiting on the pages for Zurich and Lucerne.

Along the way, the thermal baths of Baden are perfect for recovery, and the Rüeblitorte, the canton's carrot cake, serves as a reward 🥕. The region's half marathon calendar is waiting for your next goal: it's up to you to choose your pace and your finish line 🏅. With a bib in your pocket, training instantly takes on a different flavor.
