Triathlons in the Canton of Aargau

Swim, bike, run: the canton of Aargau brings all three ingredients together within a few kilometers of each other 🏊. Lake Hallwil offers mild water in summer for open-water swimming, the Aar and the country roads host bike rides, and the riverside paths serve as an open-air running track. The town of Zofingen is known to every multisport athlete for its duathlon, and this taste for combining disciplines can be felt throughout the canton. Local clubs offer brick sessions on weekends, and indoor pools take over as soon as the weather turns bad.

No triathlon is yet listed on the Finishers calendar for Aargau, but training there goes very well. Swim sessions fit in between June and September, when the lakes exceed 20°C, while bike blocks take advantage of quiet roads and hilly loops around the Fricktal. Bike-to-run transitions can be practiced on the cycle paths that run along the river near Aarau 🚴.
