Ozone Endurance Challenge run (#OEC) is a lovingly crafted, yet simple, family friendly event directed by Will Jorgensen and some of The Pistol Ultra Run team. It will take place May 27-31, 2020, at beautiful, family friendly Camp Ozone near Rockwood, Tennessee (near Knoxville).

Runners will follow a 2.0 mile USATF certified (TN18022MS) loop course through the camp and the surrounding woods around Ozone Lake and Fall Creek. The course consists of about two thirds shaded double track dirt which is almost all flat and relatively smooth (for trails). Then for variety, there are some sections of shaded/sporadically shaded gravel drive thrown in (with a grass shoulder to run on, if you prefer). The overall elevation gain is only about 60′ per mile.

This event features timed races for 6, 12 (both day and night flavors), 24, 36, 48, 72 and even a super crazy long 96 hours! It is a great course for beginners and veterans alike, walkers and runners. Kids of any age are welcome to become a Zoner too! (Super cheap fees for those under 10. And they are eligible for finishers awards too!) There will be a full service aid station with plenty of great food at the start/finish area, which you will pass by every 2 miles.

To be an official finisher and score a medal, you only have to complete one 2 mile loop. How easy is that?! But of course your goal is to complete as many laps as possible within your chosen time limit. If you complete 50 miles or more, you will the proud new owner of a Ozone Endurance Challenge mug. And if you’re a really crazy Zoner and crank out 100 or more miles, you will really step up your bling collection with a super cool belt buckle. So…how many laps can you deliver?

Besides getting to enjoy some quality trail time with all your crazy running peeps, some great race support, and swag, this is one event you can really feel doubly good about. A significant portion of your registration fees go directly to the camp owner, Children’s Bible Camps, to help with their programs. A big thanks for your support!

One final note….
As much as we’d like to, there are no refunds, deferments, or transfers of paid entry fees or bibs, meal tickets, etc, regardless of the circumstances. Many of the items such as shirt sizes are custom ordered many weeks ahead of time. So please don’t even ask. Consider this before you register. Thank you!
