Triathlon Delft

About the race

Triathlon Delft is an accessible triathlon in the Delftse Hout, organised by Stichting Triathlon Delft. The race is built around short formats: the DVA Kidsrace, 1/16, 1/8, 1/4, relay and a business race, with start and finish on the island by Plané and a Parc Fermé a short walk away. The official distances range from 100 metres swimming, 5 kilometres cycling and 1 kilometre running for the Kidsrace to 1,000 metres swimming, 40 kilometres cycling and 10 kilometres running for the 1/4. Rolling starts and clear start series keep the day calm, especially for participants tackling their first triathlon or first team race. At the same time, the 2026 anniversary edition gives the event an extra local character.
