Start: Badstraße 100, Finish: Frankenstadion, 74072 Heilbronn, Germany
The 24th Heilbronn Trollinger Marathon is a long-established road running event in Heilbronn, Germany. The main race day is Sunday 10 May 2026 with family-friendly side events across the weekend (including children's and youth Mini‑Trolli races held on 9 May 2026). The programme includes the full marathon (including Duo‑Marathon and relay/staffel formats), a half marathon, 10 km and shorter community runs, walking and Nordic walking options.
The routes pass through the Heilbronn wine region and visit towns such as Flein, Lauffen and Brackenheim, offering scenic vineyard views and several aid stations along the course. Notable course features include the Haigern ascent and an estimated ~400 m total elevation on the full marathon; GPX route downloads, course maps and checkpoint/aid-station information are published by the organisers. New for 2026 is the Duo‑Marathon, allowing two runners to share the marathon distance.
Entry and timing are administered via the official registration service (Datasport) and via the event website. The race is organised by Heilbronn Marketing GmbH and is a member of German Road Races e.V.; the 2025 edition recorded over 8,400 finishers. The event emphasises community engagement through volunteer recruitment and local sustainability actions and forms part of the regional marathon series/trilogy.
