Sparkasse Three‑Country Marathon at Lake Constance

The Sparkasse 3-Länder-Marathon am Bodensee is a cross‑border running festival that starts on the Lindauer Insel (Lindau, Germany) and finishes in the Bodensee‑Stadion in Bregenz, Austria. The event combines elite and mass participation races under one weekend brand and is promoted with the tagline “GRENZEN GIBT ES NUR IN DEINEM KOPF.” The series offers multiple distances from a full marathon to youth and children’s races, and the organiser publishes course maps, AIMS certification documents and logistical information for international participants.

The event highlights include a multi‑country route through Germany, Austria and Switzerland, dedicated youth and children’s programmes, and free travel arrangements for participants within Vorarlberg and from designated border stations. The race weekend features side events such as a sport expo, a pasta/social evening and live coverage, and the organiser SEG Sport Event GmbH coordinates registration and athlete information on the official site. Large entry numbers and historical results archives demonstrate broad international participation and an established organisational structure.
