Rad Marathon | Tannheimer Tal

The Rad Marathon | Tannheimer Tal is a multi-distance road cycling event held in the Tannheimer Tal high valley, scheduled for 5 July 2026. The organiser pages present four official distances (66 km, 103 km, 138 km and 214 km) that traverse scenic Alpine roads and passes, with the long route offering roughly 3,500 metres of ascent. The event is branded under RAD‑MARATHON and is supported locally by the Tannheimer Tal tourism organisation; registration is handled via the event's online registration partners and GPX route downloads are provided for competitors.

The main race day sits at the end of a broader Rennrad‑Woche (road‑bike week) of guided rides and workshops in the region, with on‑site services including packet pickup and an expo in the Tennishalle Sägerklause in Tannheim. Start and finish are staged in the centre of Tannheim (Ortszentrum) and the programme notes specific race‑day starts for the distances alongside rider briefings and a prize ceremony. Participants are advised to consult the organiser pages and the registration/athlete information for final start waves, equipment requirements (for example a headlight requirement in tunnels on the long route) and detailed logistical information.
