Cancelled Event


Important Update

Due to the uncertainty with COVID-19 we have made registration for this event a waitlist only because we feel it is irresponsible to continue to collect registration fees. We have no plans to cancel or reschedule this event and the event is not sold out as this page suggests. If the race goes on as planned, you will receive an email from Ultrasignup asking you to accept the invitation to register for this race. No money will be collected until you accept this registration. Please continue to check back for updates!

NEW Distances!

Our 6 Km option is a speedy, winding trail race with minimal climbing while our 15 Km allows runners to do the Escondido loop without having to head back out for the other Short Loop.

Also new and improved, we are having all runners finish their loops by continuing on the Pemberton Trail to Shallmo instead of coming back on the Scenic> Cinch> Escondido loop. We believe this will improve flow of the event dramatically. And it gets our Ultra distance almost right on for a 50 Km.

2020 Insomniac Waves!

We started the Full Moon waves back in 2018 when our races kept falling on full moon weekends. We had such a great time watching our runners push themselves through the night in two separate races, we decided to keep offering the second run, with or without the full moon. Welcome to the Insomniac Waves! The Insomniac Waves at Adrenaline will allow runners to head out under an almost new moon, making the blanket of stars above all the brighter as you run either the long (10 mile) loop, or the short (10Km) loop. It's a unique opportunity to run in the middle of the night!
