Come one, come all

The Transamerica Chicago Triathlon is far from a one-size-fits-all event. Race weekend is composed of a variety of special programs and competitions, each designed to accommodate participants of every ability, interest level and goal. Competitors can race as individuals, as part of a relay or by teaming up with one of our official charity partners.


All individuals are automatically placed in this category, unless you choose a different division below during the registration process. Age groups are specific to gender and consist of five year increments (e.g. 20-24, 24-29, 30-34, etc.). Note: USAT Age Groups are assigned based on your age as of December 31 of race year

Formerly known as the “Elite Amateur” division, these are extremely fast, non-professional athletes. To enroll, participants must have completed an International distance race under 2:15:00 (men) or 2:30:00 (women). Proof of times must be submitted prior to race day.

Participants who meet certain minimum weight requirements (165 females, 220 males) are able to compete in this separate division. Read more in the race competitions section below.

Athletes with physical disabilities. Two classification categories include:

  • Ambulatory: Blind, Visually Impaired, Amputee
  • Wheelchair: Upright, Tandem, Catrike

Triathletes using bikes with tires at least 1.75 inches in width are able to enroll in the Mountain Bike division.

The Chicago Triathlon also offers special programming for select groups and individuals. Each of these divisions are provided unique race services. However, unlike each of the above divisions, they are ineligible for standard USAT Age Group awards:

  • Charity and Tri Team Divisions
  • Live Grit First-Timers’ Program (read more in the race competitions section below)
  • Laid Back Wave (read more in the race competitions section below)

Participants have the option to enter the international or sprint distance relay team, consisting of 2–3 people. You can choose which person will complete each specific discipline. Team members share a single timing chip, which is passed from one team member to another in transition.


At the Transamerica Chicago Triathlon, Premier Amateur competitors will compete against other Premier Amateur athletes in their respective Open or Masters Age Group, not within the general Age Group competition. Premier Amateur participants will be seeded into the opening waves of the international distance event, competing head-to-head with other top amateur triathletes. Awards will be presented to the top 3 in each gender.

Results for Premier Amateur athletes will be included in the USA Triathlon (USAT) Age Group rankings based on their performance in the Premier Amateur Competition, just as if the Premier Amateur Competition was the only race to take place on that day.

Qualification Requirements
To compete in the Premier Amateur Age Group Competition (39 years and under), an athlete must meet the following criteria:

  • Male athletes must show proof of completing an International distance triathlon in 2015-2016 in a total time of 2:15 or better.
  • Female athletes must show proof of completing an International distance triathlon in 2015-2016 in a total time of 2:30 or better.

To compete in the Premier Masters Age Group Competition (40 years and older), an athlete must meet the following criteria:

  • Male athletes must show proof of completing an International distance triathlon in 2015-2016 in a total time of 2:25 or better.
  • Female athletes must show proof of completing an International distance triathlon in 2015-2016 in a total time of 2:45 or better.

You will be asked to provide proof of your eligibility when registering through the website. The race staff of the Transamerica Chicago Triathlon reserves the right to refuse entry into the Premier Amateur Competition.

The Transamerica Chicago Triathlon offers the Clydesdale and Athena Competition, open to male triathletes 220 pounds and over and female triathletes 165 pounds and over. To compete in the Clydesdale/Athena Competition, you must weigh-in at the Clydesdale/Athena check-in table during packet pickup at the expo on Friday or Saturday.

Athletes will start in designated Clydesdale and Athena waves. There are two weight class categories for both men and women: 39 years & younger, and 40 years and older. Participants are not eligible to compete in both a weight class division and age group divisions within the same event.

If you have registered but decide not to race as a Clydesdale/Athena, you must submit a change of entry form, which includes a $50 change fee, to be scored in the open age group division.

Anyone competing in the Clydesdale/Athena Competition will be competing for Clydesdale/Athena awards and will not be eligible for age group awards. For members of USA Triathlon, times will be included in the USAT rankings.

Originally known as the First Responders’ Competition, the program began in 2007 as a friendly wager among seven members of the Chicago Police Department and the Chicago Office of the FBI. Since then, the competition has hosted more than 1,000 participants from more than 24 agencies across the country.

In 2016, this special competition was been renamed on behalf of a new partnership with The 100 Club of Chicago. The purpose of this organization is to provide for the surviving spouses and dependents of law enforcement officers, firefighters and paramedics who lose their lives in the line of duty. This includes federal, state, county and local officers, firefighters and paramedics stationed in both Cook and Lake Counties. 

Through both public donations and private fundraising efforts, the program plans to generate more than $25,000 in direct contributions to the 100 Club of Chicago during the 2017 season. There are two ways to participate in the 100 Club Challenge: as a First Responder, or as a civilian fundraiser.  


All athletes registered in the sprint and international distance events at the Transamerica Chicago Triathlon have the option of competing in the Mountain Bike Division. Although athletes in either international or sprint may elect to ride mountain bikes, only participants who register specifically for the Mountain Bike Division will have the opportunity to compete exclusively with other mountain bike athletes for Mountain Bike Division awards.

To compete in the Mountain Bike Division, the tires on your bike must be at least 1.75 inches in width. If you have any questions or require additional information about this division please contact us.
