How to take part

  • Register for the race on IRONSTAR website and set a permission to use the training data from your STRAVA profile.
  • Registration closes at 00:00 on the competition day.
  • During the competition day, the participant goes through all the stages in the right order (RUN → BIKE → RUN).
  • The results of each participant automatically are shown on the table of results on IRONSTAR website.
  • At 23:59 the admission of the results ends. If the participant has not managed to complete the distance by this time, he is assigned the DNF status.
  • Within a week after the end of the competition, IRONSTAR checks the accuracy of the results and publishes the final list of winners.
  • Winners in the award categories are awarded with trophies from sponsors.
