“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.”

Will Murray

“It’s exciting to hear that the 5430 Triathlon Series is bringing some of the best race directors that we’ve had in Colorado to put on a few of the most iconic triathlons in Boulder.”

Neal Henderson

“So excited that 5430 is returning to Boulder! it is such an amazing series, that generates so much excitement around our sport, in Boulder.  Such a great opportunity for athletes to compete close to home, in the mecca of triathlon. 5430 Events are the BEST! don’t miss out!”

Siri Lindley

“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
