The Sparkassen TriDay at Störmthaler See is a triathlon held in Großpösna, Saxony, located at Störmthaler See near Leipzig. Athletico Leipzig organizes this event, which includes races for youth, juniors, sprint, and supersprint categories. The main open sprint field is anticipated to be significantly larger than the age-group youth races.
The sprint, youth A, and junior races follow a consistent format: a 750 m swim, a 20 km bike ride, and a 5 km run. Youth B participants, aged 14-15, compete in a reduced course: a 400 m swim, a 10 km bike ride, and a 2.5 km run. Youth A is designated for athletes aged 16-17, and juniors are aged 18-19. This marks the event's eighth year, maintaining its character as a local, organized race day rather than a large festival.
