Don’t miss your chance to join the club—if you’re not signed up by May 1st, you'll have to wait until next year. Be part of the action and make 2026 the year you run them all!

How it works:

You’ll pay one flat rate for the entire series, with the freedom to pick any distance in each race. This fixed price remains the same, but it’s only available until the first race starts on May 2, 2026. 

The fine print:

If you are already registered for one of our 2026 races and would like to sign up for the series instead, shoot us an email at racedirector@solekids.org!  Unfortunately, we are unable to apply discount codes or offer refunds/deferrals for the series. Lastly, the final race is a half marathon only, keep that in mind when picking your other three distances.
