Door County Triathlon Half Iron Fills

The Door County Triathlon Half Iron filled to its capacity of 1,000 participants a full three and a half months before race day.

Less than 300 openings remain in the sprint distance course, which is also capped at 1,000 participants. The sprint takes place July 16, while the half iron will be held July 17.

A waiting list is not maintained once the event is full; however, participants may transfer their entry by emailing through the website. Participants must find someone to buy their entry, which can be done on the Door County Triathlon Facebook page.

Also, the triathlon is adding a mixed-gender elite wave to the start of both the Saturday Sprint and Sunday Half Iron events. Per USAT rules, competitors in the elite waves will not be eligible for age group ranking or awards. Participants will only appear in the overall standings and will only be eligible for overall awards. Participation is strictly available upon request by emailing the race director at [email protected].
