Long-distance triathlon in Europe

Planning your race

The classic long-distance triathlon uses guideline distances of 3.8 kilometres swimming, 180 kilometres cycling and a marathon run of 42.2 kilometres. Season planning should consider not just the date but also course elevation, potential weather conditions and race-day nutrition. A flat route and a course with substantial climbing can create very different demands. Swim starts, transitions and the number of laps also affect preparation. The listed distances are not a promise for every event: local conditions or revised race guides may produce variations. Check time limits, eligibility and entry deadlines on the official race website. A confirmed date offers greater planning certainty than a provisional listing. This calendar supports comparisons across Europe but does not replace the organizer’s binding information.
