Four nights is the longest extension worth building around the ADAC Marathon Hannover, and Berlin suits it precisely because almost nothing about the city demands anything of tired legs. It is flat, it is served by one of the densest urban rail networks in Europe, and every attraction worth seeing sits within a short U-Bahn or S-Bahn ride of the last one. The direct ICE from Hannover Hauptbahnhof takes around 1 hour 40 minutes to 1 hour 50 minutes, with departures running through the day; Deutsche Bahn's discounted Sparpreis fares release around six months ahead of travel, so booking the outbound leg early, as soon as the race date is fixed, is worth the modest effort. April in Berlin brings unpredictable, changeable weather, warm and bright one afternoon, sharp and wet the next, and the parks are only beginning to green rather than in full spring display; pack layers rather than assuming settled conditions either way.

Nights One and Two: Mitte and the Museum Quarter

Berlin's centre sits almost entirely at one elevation, built out from the Spree river with no significant hills to interrupt a day of sightseeing. Museum Island, a UNESCO World Heritage complex of five museums on an island in the Spree, is reachable on flat paved paths from most of Mitte, and a single museum ticket covering ground-floor galleries is enough for a first day without needing to commit to stairs between every level. The Brandenburg Gate and the flat, straight run of Unter den Linden nearby make for an easy, level walk between two of the city's most recognisable landmarks, with cafes and benches along the way for whenever the legs ask for a break.

For accommodation, a well-connected mid-range hotel in Mitte, within walking distance of an S-Bahn or U-Bahn station, keeps every attraction in this section within a short, flat journey; a quieter option slightly further out in a residential district trades a few minutes of transit time for a calmer night's sleep. For food, the city's currywurst stands are the obvious low-effort option for a first, uncomplicated meal, while the restaurant clusters around Hackescher Markt offer a wider, more considered range for an evening when sitting down properly feels like the better choice.

Nights Three and Four: Tiergarten and Further Out

By the third day, Berlin's Tiergarten, the large central park running between the Brandenburg Gate and the western districts, is worth a slow, flat loop of its paved and packed-gravel paths; a full circuit runs to several kilometres, but shorter sections can be walked and exited at several points via nearby U-Bahn stations, so there is no obligation to finish what has been started. The Reichstag building, with its glass dome reached by lift rather than stairs, gives a wide view over the park and the government quarter for very little physical effort, though the dome requires advance online registration and should be booked before travelling rather than assumed available on the day. For a longer excursion once the legs have properly recovered, the East Side Gallery, a preserved stretch of the Berlin Wall painted with murals along the Spree, sits on flat riverside ground and is easily reached by S-Bahn from the centre. Potsdamer Platz, a short walk or a single U-Bahn stop from the eastern edge of Tiergarten, offers a modern counterpoint of glass towers and shopping arcades on entirely level pavement, a good option for a lower-effort afternoon between the two larger park days.

For the final nights, staying in the same area or moving toward wherever the departure connection is easiest keeps the last day simple. For dinner, the Kreuzberg district's dense concentration of Turkish and Middle Eastern restaurants, reflecting one of Berlin's longest-established immigrant communities, is worth the short transit ride for a meal that is specific to the city rather than interchangeable with anywhere else in Germany.

Getting Home

Berlin offers two sensible return routes, and which one applies depends on whether the trip continues or heads home from here. To return to Hannover Hauptbahnhof, the same direct ICE service runs the roughly 1 hour 40 to 1 hour 50 minute journey, connecting onward to Hannover Airport (HAJ) via the S5 line in about 18 minutes. For runners flying onward directly rather than looping back through Hannover, Berlin Brandenburg Airport (BER) is reachable from central Berlin by direct S-Bahn or regional train in around 30 minutes, a simpler option if the return flight is out of Berlin rather than Hannover. Check current timetables for whichever route applies before booking a specific flight time.
