The organiser calls the marathon a profiled loop through the vineyards of the Swabian Unterland and puts its climbing at about 400 m. The 2026 route climbs 252 m in all, between 156 m at the lowest point and 259 m at the highest, with the start and the finish both near 157 to 159 m. A watch adds every short rise, so it will read more than 252 m, and the two figures are not the same measurement.

The marathon page says the start is on Heilbronn’s Badstrasse at the height of the Marinekameradschaft. The course goes to the Götzenturm bridge, over the Neckar and along the right bank to Sontheim. After Flein a climb leads to the highest point, the Haigern near Talheim, where the half marathon turns north. The marathon goes west through Lauffen, where it crosses the Neckar again, towards Brackenheim, then back via Nordhausen and Nordheim to Heilbronn. In the district of Klingenberg the half-marathon course joins it again, and the race ends in the Frankenstadion. The route described is the organiser’s 2026 one.
