The Tangermünder Elbdeichmarathon runs two laps from the harbour of the Hanseatic town out into the Elbe floodplain of the Mittelelbe biosphere reserve. With barely 140 metres of gain over 42 kilometres it is effectively flat, but it asks for two very different halves: the first out on the country road through the villages of Bölsdorf and Buch, the second almost entirely alone on the Elbe dyke path.
Start and finish are on the harbour promenade below the old town of Tangermünde. The first lap is the half marathon: out on the country road to Bölsdorf, on through Buch to the turnaround near Schelldorf, then back along the Elbe dyke path to the harbour. The second lap leaves the road out and runs as an out-and-back on the dyke path through Buch and Bölsdorf, turning around about a kilometre short of Schelldorf.
Elevation is barely a factor. Around 81 percent of the course counts as level, the whole profile sits between roughly 32 and 47 metres, and there is not a single categorised climb. What remains of the 143 metres of gain are the ramps on and off the dyke crest.
The character of the two laps, by contrast, differs sharply. The first passes through the villages of Bölsdorf and Buch, where the organisers set up their pockets of support; the second runs almost entirely along the open dyke with a view of the Elbe, past horse paddocks and largely without spectators. The field is capped at 2,300 entries across all distances, and the race has a reputation as an insider's tip: Marathon4you ranks it third among the eastern German states.

Climb categories follow the road-cycling convention and rate the terrain itself (length and gradient) regardless of sport: Cat. 4 marks the easiest rated climbs, Cat. 1 the hardest, and HC (hors catégorie, “beyond categorization”) is reserved for the most brutal ascents. Short climbs below the Cat. 4 threshold stay unrated.
The real opponent on this course is not the profile but the wind. A dyke in the open Elbe floodplain offers no shelter at all, and because both laps are out-and-backs you get every direction once from the front and once from behind. On the tailwind section, deliberately hold your planned pace instead of banking the free seconds, because they come due twice over on the way back.
The race is decided on the second lap from kilometre 21. It leaves the road and runs entirely on the dyke path, without village stretches, without spectators and without any change of view. If you ran the first lap too fast in the slipstream of the half marathon field, there is neither a group nor a descent here to fix it. So plan the first lap deliberately at the lower end of your target range.
Two practical points: the surface alternates between the tarmac of the country road and the firmer but less even dyke path, which costs differently at the same pace. And the six-hour limit is generous, with aid stations every three to five kilometres, so an honest, even plan genuinely works here.

A marathon on this profile takes roughly 2:45 to 5:30 hours depending on your level; the limit is six hours and placings are by gun time. Entry is open to anyone turning 18 in the calendar year of the race.
The demand is steady aerobic work with no terrain-driven interruption at all. There is no climb to change your rhythm and no descent for recovery. Your body runs at almost identical cadence and muscle load for four to five hours, which makes fatigue very uniform and therefore late but heavy when it arrives.
That sets the training focus: long runs of 30 to 35 kilometres without changes of gradient, ideally on dyke or field paths, with the last ten at marathon pace. Add sustained tempo runs that practise exactly what the course asks for, namely a constant pace with no external structure for an hour and more.
Conditions belong explicitly in the plan. Mid-April on the Elbe means cool air, high weather uncertainty and above all exposed wind on the dyke. Deliberately do part of your long runs into a headwind and in open terrain, and test clothing that still works at ten degrees with a crosswind over five hours.
