Mile High Trifecta Challenge

Are you ready to experience the ultimate athlete’s high in the state of Colorado? In 2019 we are bringing you the Mile High Trifecta. Tackle three of the most epic races in the state as we combine IRONMAN Boulder, IRONMAN 70.3 Boulder AND Rock ‘n’ Roll Denver Half Marathon into one quest for glory! Your reward? The highest sense of accomplishment along with an exclusive branded jacket with the Mile High Trifecta logo to wear with pride. Begin your journey with IRONMAN Boulder in June with scenic views of the Flatirons and a flat and fast bike course. Then, return to the triathlon-centric town of Boulder for the 70.3 in August and finish off your 2019 challenge with the 10th anniversary of Rock ‘n’ Roll Denver Half Marathon in October. Only a few will complete this Mile High Trifecta! Will you be one of them?
