Race Description:
There will be 6 hour, 12 hour day, 12 hour night, 24 hour, 36 hour, 48 hour, 72 hour, and a crazy long 96 hour timed races. Pick your time and run or walk as much or as little as you like. You compete with the people in your time slot. Different race lengths will start at different times, so everyone finishes closer to the same time. When you are done running, we encourage you to stay around to cheer on others and enjoy the camp facilities. Then at 11:30 am Sunday, there will be a celebration barbeque lunch (must be selected during the online registration) followed by recognition and awards for the Zoners who place. It’s a great family like event well worth staying for.

Six hour and 12 hour day people….plan to return on Sunday or stay for the weekend. Volunteer, hang out by the course and cheer others, enjoy the campfire, and enjoy the camp activities. You can leave, of course, but we really want everyone to enjoy the entire weekend, if you so desire.

Those staying in an RV are permitted to have a small, QUIET generator right next to their RV. Since the RV parking is next to the lake, the noise will travel. So PLEASE, be considerate of everyone else.

Parking Permit:
Check out the parking map at the bottom. There are specific areas for cabins, RVs, campers, and then general parking. Upon arriving, please park in your specific area. Then walk to the start/finish area for check-in. Those in cabins and RV spots must get a parking permit at check-in.

If you are driving an RV, please do not continue past the Fall Creek Bridge at the upper end of the lake. (There are no good turn around points past there.) Proceed back and find an RV spot along side the lake/road. Then walk to the start/finish area on the other side of the lake and check in.

Please be VERY respectful of the camp property. Avoid rutting or otherwise damaging grass and other areas. If it has been raining and/or the ground is soft, you may be instructed to park in alternate areas that are further from the course. Thank you in advance for your understanding and cooperation.

Race Check-in:

  • Prior to each race beginning about 90 minutes before race start.
  • Closing 30 minutes before race start.
  • Everyone, including your guests, will need to sign our waiver.

  • Each runner will have a bib number. Bibs must be visible at all times. If you put it on wrong, under something, cut it, tear it, fold it, etc. then your miles may not count!
  • All runners will be chip timed with live results for the entire 96 hours. There will be a leader board showing placements during the entire race.
  • In addition to the timing mat at the start, there is one at the upper end of the Fall Creek Trail out-and-back section. You must cross both of these timing mats for each loop to count.
  • If you are going “off course” to sleep in your tent, cabin, or vehicle, you MUST sign out on the TAKING A BREAK clipboard in the timing area, and then sign back in when you start again. This lets the timer know why there might be huge gaps of time between laps. During your event time, you may not leave Camp Ozone for any reason unless you are officially stopping AND have signed the FINISHED clipboard or gone through the finisher’s chute (which will be put up Saturday afternoon).



There will be first aid supplies at the aid station. All major medical emergencies will be reported to 911.

Race Rules:

  • Only complete laps count. There is no credit for partial laps. Your distance is based on the number of completed 2 mile laps within the time you registered for.
  • Final results will be calculated based on each runner’s total mileage at the call time as determined by that runner’s last completed lap.
  • If you are struggling at any point in the run, race officials will have the right to evaluate you, and it will be their call if you will be allowed to continue. These decisions will be made with your safety and desire to finish in mind.
  • If you decide you are done running/walking/crawling before your time is up, come in to the start/finish area, tell the timing staff and sign the FINISHED clipboard. Your decision is final. Once the finishing chute is up Saturday afternoon, simply go through it when you are done.
  • Unsportsmanlike conduct, course cutting, littering, or violation of any of the camp rules or any of the policies set forth here will be grounds for disqualification.

Aid Station:

  • There will be one fully stocked aid station at the start location next to the start/finish area. You will pass by this aid station every two miles.
  • There will be plenty of typical race foods available. Water and sports drink (Tailwind and Gu Brew), gels, salty items, cookies, fruit, pickles, potatoes/salt, PB&J and PB&H, ice, etc. and a few specialty items. If you have special dietary needs/electrolyte drinks/etc, please plan to bring your own food/nutrition.
  • We also have a few runner necessities available: Vaseline, electrolytes, etc. Please bring what you feel is essential for you. If we don’t have it, and you didn’t bring it, DON’T complain. Know what you need to run in crazy circles for the length of time you signed up for.

This is a cup free race. Runners provide their own hydration systems.

This is a NON lighted course. Runners provide their own lighting system.

Ticks (tiny and big). Sometimes LOTS of them! (Bring insect repellent. Check your body carefully.) Also poison ivy and snakes (including poisonous). No Bigfoots or Sasquatch have been sighted yet!

Personal Aid Stations/Drop Bags:
Runners will be allowed to set up personal aid stations at their tent site or alongside the course in a designated area. (Depending on where you park, your car may not be next to the course.) We will have an area designated for crews to set up beside the course, along entry road (see map). First come, first served. Please minimize the area you use as much as possible to allow for others coming in.

Non-Runner Support:
Parking and non-runner support is VERY limited! We welcome you to bring your family and /or crew, but please don’t invite your entire running club to come cheer you on. Now if they will sign up for one or more volunteer slots, bring everyone you can! ☺

Runners may have crew support every lap. All crew MUST sign a waiver at the check-in.

You are allowed one pacer with you at anytime while you are officially still on the course. They must be within your sight at all times. Pacers are for moral support only and for guidance if you start to hallucinate. NO MULING! You still need to carry your own stuff. Ask for a Pacer Bib for your pacer at check-in. One pacer bib per runner. All pacers MUST sign a waiver.

Without volunteers, this event wouldn’t happen. Please encourage all your friends/family/etc to come support you and event for at least one or more time slots. Especially the hardest ones to fill early on and during the night. A huge thanks! Here’s the link:

None….but if you sign up, you agree that you are responsible for planning your training, gear, hydration, and fueling. Your lack of preparation or running knowledge is NOT the race director’s, volunteers, or anyone else’s fault. You should know how to doctor basic running injuries….like blisters. Come prepared.

If you sign up, you agree to READ the written information and the emails from the director. AND you agree not to whine. We will be encouraging and helpful. We will not hold your hand or have volunteers every 10 yards holding supplies for you, giving you a hug, tending to your every wish, and offering a teddy bear to console you. ☺

Contact Information:
If you have any additional questions, please EMAIL: As soon as we are able, we will reply with short, straight forward answers to questions that are NOT answered in this document.

There will likely be changes that we decide to make before, during, and/or after the event. Thank you in advance for your understanding and cooperation.

Last, but not least……..
We are all here to have a great time. Do your best anti-rain/heat dance, and get ready for a running PAR-TAY!!!
