Course & Elevation
The Deutsche Post Marathon Bonn is a spring marathon in the former West German capital, held on a Sunday in April, with the start in the city centre and the finish on the Marktplatz in front of the Old Town Hall. It has been run since 2001, organised by the Cologne agency MMP, and has had a half marathon since 2005. A 10 km run, a marathon relay and a school marathon take place on the same day. Through 2026 the marathon was two laps of a flat circuit: from Belderberg by the Koblenzer Tor over the Kennedy Bridge to Beuel, back across the Rhine, along the riverbank to the Rheinaue and a turn on Ludwig-Erhard-Allee, then past the Post Tower and along the Museum Mile to the Museum Koenig, the university and Bonn Minster, before the second lap. The 2027 edition is planned on a new route that stays on the Bonn side of the Rhine, with start and finish remaining in the city centre. The time limit is six hours and the minimum age is 18. The 2026 edition was sold out at 22,222 registrations across all events, including a half marathon capped at 12,500 places.
