Wiesbaden is the capital of Hesse and Germany's most elegant spa city - the hot springs that emerge at 66°C in the old town drew Roman soldiers, Goethe, Dostoyevsky, and the Kaiser. The Kaiser-Friedrich-Therme is the reason to come post-marathon: a Roman-Irish bathhouse from 1913 in a Jugendstil building where the recovery sequence (warm bath, hot bath, steam, cold pool) runs for as long as you want.

Getting There

RMV train or S8/S9 from Frankfurt Hauptbahnhof to Wiesbaden Hauptbahnhof: approximately 40 minutes. Direct services run frequently throughout the day. Race participants travel free on the RMV network with their race number on race day; the Wiesbaden connection is within the RMV zone.

Kaiser-Friedrich-Therme

Kaiser-Friedrich-Therme on Langgasse (kftherme.de, entry approximately €7-15 depending on day and time): the thermal bathing house built in 1913 in the Historicist style - a Jugendstil building with mosaic interiors, Roman bath architecture adapted for the Wilhelmine era. The water is natural hot spring water from the Kochbrunnen (the main spring, which emerges at 66°C and is cooled to bathing temperature).

The bathing sequence in the Roman-Irish tradition:

  1. Warm room (Tepidarium): 36-40°C, the acclimatisation stage
  2. Hot room (Caldarium): 45-55°C, the main sweating room
  3. Steam room (Laconicum): herbal steam, high humidity
  4. Cold pool (Frigidarium): the plunge, circulation stimulation
  5. Rest room: horizontal, wrapped in towels, the recovery phase

Post-marathon, this sequence treats the muscle inflammation and the psychological decompression simultaneously. The facility is open daily; weekday morning visits are significantly less crowded than weekends.

Note: The Kaiser-Friedrich-Therme is traditionally nude bathing (mixed). Swimwear is permitted in the outdoor pool. This is the norm in German spa culture; if this is a concern, the Thermalbad Aukammtal on Leibnizstrasse has a swimwear section.

The Kurhaus and Wilhelmstrasse

The Kurhaus (1907, Friedrich von Thiersch): the centrepiece of Wiesbaden's belle époque casino and concert hall complex, set in the Kurpark. The building is the largest casino in Germany (Spielbank Wiesbaden); the concert hall operates year-round. The grounds and the colonnade are freely walkable.

Wilhelmstrasse (the Linden-bordered main promenade from the station to the Kurhaus): 1.2 km of boutique shops, cafes, and the grand hotels of the spa era. Walking its length and back is the correct introduction to Wiesbaden's scale.

Kochbrunnen (on Kochbrunnenplatz): the main hot spring, visible as a steaming iron structure in the square. The water (66°C, containing 15 dissolved minerals) flows continuously and can be tasted for free from the drinking fountain - highly saline, sulphurous, the authentic spa water experience.

The Neroberg

The Neroberg (245 metres above the city) is reached by the Nerobergbahn - a water-counterbalance funicular from 1888, the oldest funicular in Germany, free to ride. At the summit: a Greek Orthodox chapel (the Russian Chapel, built in 1855 for a Russian duchess who died in Wiesbaden), views over the Rhine-Main plain, and a swimming pool.

For post-marathon Day Two, not Day One - the walk back down from the summit involves steps.

Where to Eat

Lumen in the Aukammtal complex: the restaurant attached to the Thermalbad, good for post-bath lunch. Restaurant im Kurhaus for a more formal dinner in the historical building. Alte Münze on Mühlgasse for Hessian cooking in the old town.

Practical Notes

  • Wiesbaden is 40 km west of Frankfurt.
  • The Kaiser-Friedrich-Therme is closed on certain days; check the website before going.
  • The return train to Frankfurt runs until late evening.
  • Rhine ferry: From Wiesbaden Schierstein harbour (taxi from centre), ferries cross the Rhine to Rüdesheim - an extension into the Rhine wine country if energy allows.
