 The Vashon Island Multi-Sport Festival Weekend is on Sunday, July 6th, 2014. The weekend will have something for everyone!

Sunday 7/6: XTERRA Vashon Off-Road Triathlon, Trail Run 

The events will be held at King County's Dockton Park on Maury Island, which is located at: 25998 Dockton Rd. SW, Vashon, WA 98070. The triathlon is sanctioned by USA Triathlon, the governing body for triathlons in the United States. All racers must be members or purchase a one-day license.

The Heart of the Sound Triathlon (road tri) has been canceled for this year. We are planning the race for next year, but realized this year it was just not feasible to put it on. We will be issuing refunds to those who have already registered. Thank you for your support of the HOTS triathlon. For those that are more adventurous, there will be a group of people doing swim/bike/run on Saturday on their own, and you are welcome to join them!

June 23rd until July 4 $80.00; Day of Race is $85.
June 23 until July 4 is $110; Day of Race is $115.
XTERRA Trail Run June 23 until July 4 is $20; Day of Race is $25.


The swim for the triathlon will take place on a route in protected Quartermaster Harbor,  a half mile salt-water swim where most (but not all) wear wetsuits. The length is accurately measured. The course will be triangular, and be clockwise or counter-clockwise in order to deal with the tide.

The mountain bike leg will be three loops on the dirt trails of Dockton Park.

The run for the XTERRA is again on the hilly trails of Dockton Park for 5k, with challenging hills.

The individual legs and transition times are kept track with chip timing.

Congratulations to all of our contestants prior years, you are Triathletes!

The Triathlon is unique in the Seattle area - featuring a salt water swim.  The race start, transition and finish takes place at Dockton Park on Maury Island.

Here are the distances for the events.  The Sprint Triathlon is $70 for an individual and $100 for a relay team (there is a late fee of $10 for entries). 

It is important for all participants to be familiar with the rules governing the sport that are promulgated by USA Triathlon (USAT).  Our Course Marshals will be checking for these violations, so before you touch your bike please click your helmet strap.  We will have bar end plugs at the start for those without; if you try to ride without them you will be pulled.  No throwing those gel packets away while riding - littering is a punishable offense. We are very sorry about the "no iPod/mp3" rule; athletes must be able to hear Course Marshal instructions as well as traffic (and 2-way radios are not allowed yet in USAT events, unlike the Grand Tours of bicycle racing).

If you are not a member of USAT, you must purchase a one-day license from USAT at registration. 

Refund Policy: if you pre-register we will transfer your registration your registration to the next year's event; if you register on race day and withdraw prior to the event we will refund your entry fee.  We cannot transfer or refund a USAT membership fee.
