Coronavirus (COVID-19) Important Message

Message to our athletes:

As I am sure many of you already assume, we have to cancel the remaining two races of the LA Tri Series on ( April 18 and May 9). The plan is to rollover registration of these two races to their respective races next year. When we open registration for next year’s races, I will send everyone a comp. code they can use to register.

If these arrangements do not work for you, please contact me at to discuss other options.

A few people have asked me about our no refund policy. I would like to take a minute to explain.  Putting on these events takes over a year of effort, preparation and thousands of dollars. There are many expenses that must be born far in advance of the event. They can include park permits, service contracts, marketing, swag, bibs, supplies, etc.

Without a “no refund policy” to cover extreme situations like the one we in which currently find ourselves, it would be impossible for small businesses like mine to undertake the risk of holding these events.


I want to close with a heartfelt thank you for all the support you have given me every year and particular this year.  I look forward to seeing all of you next year.

Carolyn Wolk

World Class Events

We pride ourselves as a grass roots organization and make it our goal to provide athletes and sponsors with a world class experience. We are honored to have many of the most recognized elite athletes in the sport call both “Bonelli” and the “LA Series” a regular stop in the annual triathlon circuit.

An Amazing Venue

Bonelli Park is the perfect venue for the ultimate triathlon course. The lake in the middle of LA is easily accessible, the bike course has rolling hills and no left turns to navigate against traffic. The run is a mixture of cross county and beautiful scenery.

Fun for Everyone

Our event has a super relaxed setting were spectators can mingle with the athletes afterwards and watch the run and bike course — all from really close to the finish line. We also get some of the biggest names in the sport competing in every event. It’s the perfect mix.
