Tallinn University of Technology and IRONMAN Estonia are joining forces again for the 2025 sports summer, inviting the university community to take part in one of the world’s biggest and toughest challenges – the IRONMAN triathlon. Additionally, five exemplary individuals from the university will be selected, whose journey to IRONMAN 70.3 Tallinn we can all follow and support.

What is IRONMAN?
IRONMAN is one of the toughest and most prestigious triathlon competitions in the world, where athletes complete three endurance disciplines in sequence:
- Swimming: 3.8 km
- Cycling: 180 km
- Running: 42.2 km (full marathon)
The total length of the IRONMAN triathlon is 226 km. Participants must finish the IRONMAN Tallinn within 17 hours.
IRONMAN 70.3 is half the distance of the full IRONMAN, with:
- Swimming: 1.9 km
- Cycling: 90 km
- Running: 21.1 km (half marathon).
IRONMAN 70.3 Tallinn also includes a team event, allowing each team member to complete one discipline. This is an excellent introduction to the IRONMAN festival, providing participants with a first step toward the full individual race.
The time limit for IRONMAN 70.3 Tallinn is 8 hours 30 minutes.
TalTech X IRONMAN Estonia
IRONMAN Estonia and TalTech first collaborated in the fall of 2023, preparing 15 brave TalTech employees for the major triathlon event. By August 25, 2024, many of them successfully completed it.
