Read below to make sure you understand the changes

The Silicon Valley Kids Triathlon (“SVKT”) is one of the country’s largest triathlons specifically for kids aged SIX through SEVENTEEN.

This year, we are moving to a new venue, the beautiful and recently opened  Kathleen MacDonald High School . The swim will be in the pool and the run on the track as usual. The bike course will continue to be on closed roads. There should be plenty of parking, the bike course has easy spectator viewing, and the whole event will be more compact.

Because we are in a new venue with a smaller pool, we are cutting out some of the events that have been traditionally held in order to make the event smaller as we gain more experience with this venue.

Triathlon

There are two triathlon events to choose from.

Competitive  Triathlon is for kids aged 6 to 15 who are ready to race on their own. It is timed and there will be awards. No parents will be allowed in transition at any time . (We will have transition clinics to teach the kids everything they need to know.) Your child needs to be able to swim across the pool without stopping and without swim aids; no training wheels or balance bikes either.

The  Super-Sprint is for kids 11 to 17 . Kids 11 to 15 can choose the shorter distances of the traditional event or the longer distances of the Super-Sprint.

Not sure which event to sign up for or if your child is ready for the competitive event? Read this guide .

Non-Competitive and Duathlon Events

There will be no Non-Competitive Events at this race . But Menlo Park Kids Triathlon will still have them.

There will be no Duathlon either .

After some experience at this venue, we hope to bring these events back.

NorCal Youth State Series

This event is part of USA Triathlon's Youth State Series. Because there is so much overlap in participants, we will not have the Bay Area Kids Triathlon Series this year . We encourage everyone to participate in the entire state series, including the Sunnyvale Kids Splash and Dash (date TBD) and the Oakland Tri Club's Splash and Dash on October 25th. Series awards will be given out at the OTC Splash and Dash.

Youth Teams and Clinics

There are two youth teams in the area: TCMTriSquad Juniors in Santa Cruz and Santa Clara County  and First Youth Triathlon Team (FYTT) in Menlo Park. Both put on clinics and workouts.

In addition, there will be several youth clinics -- especially practice tris and transition practice -- put on by Rolling Stumps Endurance . You will be given an opportunity to sign up for them as part of registration.
