2026 Arizona Sunrise Series - Rio Vista

Why run in just one event when you can save so much by registering for the whole Series! (7 total events)

And don't forget - this is a StartLine Racing Series which means big prizes!!

Get points for every event you complete, with extra points being awarded based on your age group and overall finish. At the end of the series the top 100 point earns, plus all participants that complete at least 4 of the 7 series events, will be entered into our Arizona Sunrise Series Prize Drawing.

Along with great prizes from StartLine, three people will walk away with a $500 gift card (which we suggest you use to get out of the Phoenix heat!!)

Of course we want you to participate in the Arizona Sunrise Series locally but we understand things come up. So, if you can't join us at Rio Vista Park and still want to run, get the medal and a shirt then you still can! Here is your chance to take part in this event no matter where you are! And of course, all prices include shipping! Please note that all items will ship following the event on June 13th. Because this is part of a series you will receive the main medal plus the attachment for this event only. You will not receive all 7 attachments. If you wish to register for the Virtual Series please visit us here. Prior to the event all virtual participants will receive an email with instructions on how to submit your time.

Virtual Registrations are restricted to US addresses only. If you reside outside of the US and wish to participate please contact StartLine Racing at [email protected]
