Be half of Race official, Captains can make judgement call if any runner really lagging and obviously not going to make to the finish line by 5pm, or if they look strong enough to keep going.

Chino Hills State Park Discovery Center gate will open at 5:30am. Do not arrive much earlier than that.

The races will start on time, please take care of your bathroom need before.

50K/30K races will follow different color ribbons, the color will be marked on your Bib at check-in.

Chino Hills is mostly exposed. One handheld bottle is required. Carry extra water bottle or a camel-pack depend on the weather condition or your personal need.

For keeping green environment and create less toxic trash, all runner is REQUIRED to bring at least one handheld bottle to fill the hydrations, this race a cup-free event and every runner will need to bring your own cup of some kind, we will not provide cup for water/soda. You can get a Hydro-pouch for $5 at the check-in.

The aid stations are staffed by Ultra runners giving back to others who have helped put on races for them in the past. Make sure to thank them--even if they somehow manage to spill your drink all over the place! This is a labor of love.

You must announce your race number to CHECK IN and CHECK OUT at every aid station. Again, this is for your safety, so we make sure you're not lost out on the course somewhere.

And if something happens out there, the quickest way out is on the trail. Do not get off trail for any reason and retrace your steps if you think you took a wrong turn. Watch out for each other.

Also, don't litter out there. This is not a road race with cleanup crews picking up your gel packets. If you make trash, carry it out with you to the nearest aid station and throw it out there. ANYONE CAUGHT LITTERING WILL BE PULLED FROM THE RACE. Anyone littering, but not caught, beware the wrath of Mother Nature!

If you need to drop, you must do so at an aid station. Tell them you are dropping before leaving the course. Failure to do so will ensure you never run another race in Chino Hills again!

Important Note to 50K runners (pay attention to all Red):

We will try again to allowing downgrade to 30K at Bane Canyon station this year.

Runner MUST Notify the aid station Captain Jose, so he can have HAM radio communicate to the Race BASE.

On your bib, you will be responsible to asking staff there to:

mark #1 when you first arrive at Bane Canyon Aid Station;

mark #2 when you finish Lower Alison loop;

mark #3 when you finish Bane Ridge loop.

So, DO NOT put the bib number at the “sensitive” area you don’t want to be touched at!

NEW: you MUST bring a wristband back from top of North Ridge Trail after you leave 4-corner aid station on the way back.

If you miss a number on your Bib and wristband when you across the finish line, you will be mark down to 30K, NO exception.

Also, if you downgrade from 50K to 30K at the Start, you are expected to start with 30K and DO NOT just take off with 50K.

Lastly, Chino Hills State Park has 0 tolerance on alcohol.

If caught by Ranger, will be cited and the future permit of the race will bejeopardized.

We got multiple warning already, please help us help you!

Due to the Wildfire Red Flag Warning season, event will subject to cancel if the day is fall into the condition!

Until then, let’s stay positive, cross our figures and pray it will be a nice day for us on the 9th.

Have a great race!
