The info immediately below if for Registered Triathlon Participants.


If you're a Registered athlete, It's time for you to decide how you want to handle your registration. We will be looking for your decision by August 4, 2020.

Here Are Your Options:

You're game to go Virtual - That's great!  You can switch to a virtual Black Diamond race, or another RTB event:  The Lake Meridian Duathlon or the RTB's returning event, the Summit Plummet! Be sure to take a look at those. 

You might have some money leftover due to  lower Virtual Race Prices for short course. If that's the case you can either use that for another RTB Event in 2020 or 2021 or request a refund. We will contact you for your preferences.

This option transfers your registration to the real in-person Black Diamond triathlon in 2021. We'll see you there!

We understand for some of you this might be the only option that makes sense.  If you purchased a one day USAT license, that will be done separately through USAT.  Please watch for contact from them in the next couple of weeks.  

Events are expensive - even when cancelled. Choosing this option will help us to keep our heads above water and we'll donate half of your entry to Food Lifeline in their work to fight hunger in Western Washington so others can keep their heads above water too.
