WHAT IS AN INDOOR TRIATHLON?
An "indoor tri" is the perfect way to "get your feet wet" whether you are a first timer, or a veteran looking for a motivating challenge to test and benchmark your fitness as you prepare for your next racing season! You can participate side by side with friends and family, co-workers, or individually alongside fellow triathletes. Unlike traditional triathlon, this event is based on TIME rather than DISTANCE. The further you go during a specific portion, the more points you earn toward a final score.
The 60-MINUTE event consists of 45 MINUTES OF EXERCISE + 15 minutes of transition time as follows:
* SWIM: 10 minutes (in the pool)
* + Transition #1 = 10-minutes
* BIKE: 20 minutes (on an indoor bike)
* + Transition #2 = 5-minutes
* RUN: 15 minutes (on a treadmill or indoor track)
BEGINNER FRIENDLY!
Indoor triathlons are fun, beginner-friendly events for all ability levels! Some of our indoor triathlons are even in relatively shallow depth pools (e.g. Lakeshore Sport & Fitness) where you can "aqua-jog" the swim if you aren't comfortable swimming (NOTE: Edgewater location events feature a pool with a "deep end" on one end of the pool). Any swim stroke is welcome, and since the events are time-based (not distance based), you can take breaks as needed anytime - swim 25 yards then take a breather if you need to! The clock will keep running and you may not "score" as high in total distance, but these events are all about participation - so they are great fun no matter how fast or "social" you take it because everyone starts and finishes together regardless of fitness level! So invite your friends, family, and anyone looking for a great 1-hour fitness challenge!
TRI312-SCORING SYSTEM
Based on the 312 Chicago area code, we leverage a unique 312 multiplier scoring system with a 3x SWIM + 1x BIKE + 2x RUN = TOTAL SCORE formula. With a set-time for each event, the results become distance-based using a weighted scoring formula that better replicates real-world outdoor triathlon results. This creates a beginner-friendly and fun atmosphere where everyone starts and finishes together! Ultimately, this also allows swimmers, cyclists, and runners to better complete on a level playing field and determine who is the best all around triathlete!
YOUR TOTAL SCORE =
3x Swim Distance (miles) +
1x Bike Distance (miles) +
2x Run Distance (miles)
