What is the Longmont Try-a-Tri?

Are you new to the sport of Triathlon, recovering from injuries, just getting into shape, learning how to swim, bike, and run (all together or learning a new skill), and a full sprint distance triathlon would be a bit too much? Then, the Longmont Try-a-Tri (super-sprint triathlon distance) is the right Triathlon for you to take on! 

The Longmont Try-a-Tri is not about what place you finish in, it is about having fun while finishing a TRIATHLON!


  • Swim - 200 yards
  • Bike - 4.5 miles - 3x around the bike course
  • Run - 2K (1.2 miles) - an out and back course on the side walk and bike path

Transition Area

Body Marking and Race Number

  • Race bib must be worn on the front of your body during the entire run portion of the event.

Timing and Chips

Timing chips are handed out in the pool area just before your swim start to eliminate participants accidentally walking across timing mats. Timing chips are on a comfortable Velcro & neoprene strap, and must be securely fastened to the left ankle. They may feel a little loose once you get in the water – this is normal – they will tighten back up once you get out of the pool. Timing chips are given out right before the swimmer enters the pool. If a timing chip is lost, the participant will be charged $99 to replace the chip.

Swim:  200 yards

Report to the pool deck around 9:30am to be ready for an estimated start time at 10:00 am (we usually go faster than slower).
