Drop your munchkins off before the event and rest assured that they will be in a safe, fun environment while you test your mettle in the race. We will be located in a tent close to the start/finish lines, with plenty of active games to keep busy.

Spaces are limited, so reserve yours early!

“The funnest race series ever—great swag and expo, amazing hand-built awards and great camaraderie.  Bringing back the Boulder Peak with Olde Stage Road bike course and prize money will be terrific.  Very glad to see this positive development for local athletes and folks from all over.”

“5430 Sports has provided an affordable racing experience in one of the best racing venues in the US. From A to Z, Barry and Jodee have it covered. You can bet if you sign up for their races, you’ll get your money’s worth”

 Mike Ricci


“Pam and I are so excited to hear that Barry and Jodee are coming back to Boulder and teaming with Lance and Without Limits to produce the great 5430 events that put Boulder on the triathlon racing map.  Boulder Peak was always one of our favorite races, to not only compete in, but as spectators for the unique pro race format that followed the age group event.  Always the highlight of the season.”

Warren Shuckies


“The return of the 5430 triathlon series to Boulder is an exciting development for the multisport community. The 5430 races are highly competitive with a grassroots feeling, a throwback to good ‘ole days of triathlon. The events are always well-organized and the handmade awards are innovative and worthy of display”

Joanna Zeiger



No race is ever successful with out volunteers.  5430 Sports would not be able to continually produce top notch, fun events without the help of our volunteers. We would like to say thank you to all of our volunteers by offering discounted entries to other 5430 Sports Events.
