Ruhrseen-Halbmarathon Hagen

Ruhrseen-Halbmarathon — run where the Ruhr area ends

The Ruhrseen-Halbmarathon is a firm fixture in the North Rhine-Westphalia running calendar and one of the most scenically attractive half marathons in the region. On Sunday, April 19, 2026, the field will start again. Start and finish: Seestraße 4, 58089 Hagen — directly at the Familienbad Hengstey, at one of the most beautiful spots on the Hengsteysee.

Two distances for every level

The organizer offers two routes:

• Half marathon (21.1 km) — the classic distance for ambitious runners, timing by GIT
• 10-km run — ideal for beginners, hobby runners, and anyone looking for a fast spring race

The course follows the lakeside paths of the Hengsteysee and Harkortsee, both Ruhr reservoirs that extend into the southern district of Hagen, bordering the towns of Herdecke and Wetter (Ruhr). Largely flat, with the water in view — a run where the landscape motivates you.

Organizer Stadtsportbund Hagen

Behind the Ruhrseen-Halbmarathon is the Stadtsportbund Hagen (SSB), the umbrella organization of Hagen sports clubs. The SSB organizes the run with numerous volunteers from its member clubs. The event is supported by Hagen athletes — which makes it a true popular sports event, not just a commercial one.

Hengsteysee and Harkortsee — Hagen's local recreation area

The Hengsteysee was dammed in 1929 as the second Ruhr reservoir and is now one of the most important local recreation areas in the south of the city. On its western counterpart, the Harkortsee, the course continues along the city limits to Wetter (Ruhr). Those who run the half marathon will see both lakes up close and get a cross-section of the industrial history of the Ruhr area: reservoirs were built to secure the water supply of the region.

Included in the starter package

Anyone who registers gets a lot: finisher medal, intermediate and finish refreshments, digital certificate, timing by GIT with chip technology. For members of a Hagen sports club, there is a 15% discount on registration with the code RSHM15 — a direct bonus for the local sports community.

Early bird and regular prices

The price structure rewards early registration: the early bird rate applies until October 31 — half marathon €39.50, 10 km €22.50. Regularly, the half marathon costs €49.50 and the 10 km €27.50. Late registrations on the day of the event cost an additional €10.
