The Dawn to Dusk is a serious undertaking that will challenge the most experienced of athletes, take time to prepare for this event. Before starting any training program consult a medical professional about potential risks involved.

We recommend biking, running and kayaking as ways to prepare for this race.

The Dawn to Dusk provides a challenge to experienced adventure racers and those who are new to adventure racing. However, it is recommended that racers have some experience with navigation and endurance activities. We provide a number of options for those with different experience – we have a high level of DNFs each year and you should go into this race knowing that is the case. It is solely up to you to decide which routes to take and whether they are within your abilities to finish the race. If you are a beginner to this sort of thing, we suggest that you plan out checkpoints to skip and keep time to make sure you’re progressing on the schedule you anticipate, altering your plans as you go. Dead Last is still more awesome than Did Not Finish and getting lost in the dark!

You do not need a support team for this race – it is designed to be self supporting. You will pack your gear in bins for each transition area, details will be sent out in our pre-race email sent a week before the event.


We understand you’re putting your life in our hands for the time you’re on the course and we want you to know what’s on deck should you need it:

  • We work with the local Search and Rescue team to provide EMTs and rescue equipment on course throughout the whole event.
  • We also have arrangements with CalStar, an air ambulance, and H70, the local CHP rescue helicopter for ALS and hard to reach locations.
  • On the water we have a patrol boat for kayak and boat safety.

The worst injury we have had in our 9 years was heat stroke and we had an IV in him in 10 minutes en route to the local ER in 20 minutes.

All of our transition areas and course marshals have VHF radios that use a repeater so we have communications throughout the entire course, as little to no cell phone reception is available in some of the areas we travel through.
