IRONMAN continues its global expansion in 2025 with six new races spanning three continents, strengthening its presence in key endurance sports markets. The new additions include four IRONMAN 70.3 events and one full-distance race.

The 70.3 calendar features the culturally rich Tours Metropole in France, Ironman Brasilia 70.3,  the tropical paradise of San Andres in Colombia, and two American venues – Ironman Rockford 70.3, Illinois and Ironman Boise 70.3, Idaho. Ironman Leeds, UK joins as 2025’s only new full-distance race, offering athletes a challenging course through the iconic Yorkshire Dales.

Estonia’s triathlon community celebrates the return of IRONMAN Tallinn 70.3 in August 2025 after a one-year hiatus. The race’s comeback reinforces IRONMAN’s commitment to the Baltic region’s growing endurance sports market.

Bike course Elevation Analysis: A Preliminary Overview

This chapter presents initial elevation gain review for the new 2025 IRONMAN courses based on regional topography and preliminary course mapping. Athletes should note these projections serve as general guidance rather than definitive measurements. Final elevation profiles will be compiled and verified using actual participant GPS data post-race, aggregated from platforms like Strava to provide accurate course statistics. This community-sourced data will help future participants better prepare for these challenging courses.

At the time of publication, IRONMAN Leeds organizers have not released official bike course details. Without published course maps, a thorough elevation analysis cannot be provided. Updates will follow once course information becomes available, with final elevation data to be verified using participant GPS recordings post-race.
