2023 ET Indoor Triathlon Series

One Hour, Any Skill Level, Have Fun!!

“Coach Joe and the rest of the ET crew – thanks for putting on a fabulous event today! It was my first ever tri and everyone was incredibly encouraging. Already looking to see if I can juggle my schedule so I can race again in Feb!” – Beth Y.

“I just wanted to extend a huge thanks to you and all of the volunteers who made today’s experience such a positive one. The team was extremely light-hearted, helpful, and encouraging all around. From adjusting the bikes, to providing water and towels, to ensuring everyone was performing safely within their limits, I was blown away by their tremendous efforts to help the participants in any way they could. I’m very much looking forward to the next indoor tri.” – Mike S.

“I had such a great time today! Thanks so much to my super awesome wave coach, Coach Suzy, for getting me through the event. And thanks Coach Sarah for your encouraging words at the end of my run! Also can I just say this event was a great example of how important volunteers are at a race. The encouragement from everyone was awesome! Thanks to all of you for helping to make this a great event. I look forward to the next one in February!” – Allison O.



The ET Indoor Triathlon Series presented by Experience Triathlon is a great way to become a triathlete or test your training for the outdoor race season. It’s fun and enjoyed by athletes of all levels – from first-timers to veterans. You set your own pace!

The one-hour event looks like this:

  • 10 minutes of swimming in the lap pool. Our pool is 20 yards long with NO deep end. Athletes can stand at any point. Walking is permitted.
  • 10 minute transition from the pool to the spin bikes
    • Note: please leave yourself 3 minutes or so to adjust your seat and get ready to spin. Try and get to the bikes in about 7 minutes after the swim ends.
  • 30 minutes of bike riding on the studio spin bikes
  • 5 minute easy transition from the spin area to the treadmills
  • 20 minutes of treadmill running

New for 2023! High-quality Gildan 50/50 Finisher Shirts!!

Results are measured by how far you go in each of the three events. Volunteers will record your distances.

Each athlete will have their own swim lane. Waves of four athletes will start every 20 minutes starting at 7:00 A.M and continuing until the last athletes are finished. The event can last into the early afternoon depending on the final number of registered athletes.

Please note: Wave start times for each athlete will be posted on this page the Friday prior to the event.
