Held on August 16–17, 2025, the Altwarmbüchener Triathlon—organized by Schwimmclub Altwarmbüchen under the Triathlon Verband Niedersachsen—delivers an open-format triathlon experience in scenic woodland surroundings beside Isernhagen’s lake. Events include the Triathlon XS (400 m swim, 10 km bike, 2.5 km run) for beginners, the Sprint distance (750 m/20 km/5 km, including relay options), and the Olympic or Mitteldistanz (1.5 km/40 km/10 km). Youth and children's formats run on Saturday with shorter swim-bike-run combinations. All races use chip timing via Runtiming GbR, with clearly marked transitions and road-bike cycling conducted under public road rules.
