Aarau

Aargau 5000 Switzerland

The OnGravel Checkpoint Challenge is a cycling event where the rider collects 4 viewing towers in Northern Switzerland between Aarau and Basel between May and October 2025. The route is up to the rider, but a scenic route suggestion is provided by us.

Upon arrival at the viewing towers riders can check-in via qr-code and track their progress. After two scanned towers riders earn themselves a free coffee at the participating Cafés along the route. After collecting all four towers riders qualify to participate in a raffle for gear and vouchers from our supporters.

The Challenge is free and should encourage fellow gravel or mountainbike riders to get out there and explore. Total distance is about 215km and about 3800m in elevation.
