IRONMAN 70.3 Switzerland

IRONMAN 70.3 Switzerland is a destination half‑Ironman triathlon held in Rapperswil‑Jona on the shores of the Obersee. The race features a lake swim in the Obersee, a scenic but hilly 90 km bike route and a half‑marathon run that includes the famous "Stairway to Heaven" through Rapperswil's Old Town. The event is presented as a destination race with strong local character, promoted under the tagline "Swiss Riviera Stunner" and framed by the town's lakeside views and rose gardens.

Organised by Ironman (Ironman Switzerland AG locally), the Rapperswil‑Jona edition has been staged since 2007 and offers World Championship qualification slots for top athletes.
