The 25th Hour Endurance Run

About the Event

The 25th Hour

Welcome to the 25th Hour! Once a year, on the last day of Daylight Saving Time, we can "fall back" in love with running at the newest race offering from Relentless Running Events. The 25th Hour Endurance Run is a 25 hour timed event run on a beautiful and challenging 3.6 mile trail loop. The race will begin at 9 am on Saturday and finish at 9 am on Sunday. Runners will see how far they can go, and awards will be presented for runners as they achieve milestone distances. There will also be awards for top mileage finishers. All runners will receive a branded race shirt and some extra special swag items. Hosted at Camp Grier in Old Fort, this race will include gorgeous views of Jarrett Creek, Copper Ridge, and Camp Grier Lake.

Course

The course for The 25th Hour Endurance Run is a combination of single-track trail and gravel, with a grassy loop in the lake area. The grassy area near the lake is where the official aid station and timing tent will be located. Each loop is 3.6 miles in length and has around 400' of elevation gain. The course is challenging but runnable and fair. Best of all, it's scenic and fun. The grassy field in the lake area will be available for tent camping and there will be space along the course for runners to set up personal aid stations to use during the event.

Amenities

AID STATIONS AND SUPPORT: There is a large well-stocked aid station and a water only station each lap. The main aid station is located in tent city next to the starting/finishing line. This is fully stocked with typical ultra food throughout the race and supplemented with real food around mealtimes. We do our best to accommodate dietary preferences, you will find veg options. CAMPING is FREE: If you are interested in camping the field (‘tent city’) will officially be open on Friday, October 30th at 4:00 pm for you to set up and check out the area. Tent Camping only. Sorry, no RV space available. This is a family-friendly event and runners are encouraged to bring partners, children, crew to camp for no extra charge. LODGING is available thru Camp Grier. They can offer you a bunk, room, or entire cabin on property or nearby. This is a great option for family or crew coming along. More info at https://www.campgrier.org/

Rules

The 25th Hour Endurance Run is a time-based event where runners will be ranked by how many complete laps they finish within the generous 25 hours. Partial laps will not be counted. Runners completing the same number of laps will be ranked based on the elapsed time the last lap was completed. Runners may exit the course but must return to the course at the same location they left it. The professionals from MCM Timing are scoring this year and all runners will be running with a chip-enabled bib. No pets are permitted on Camp Grier property. No open fires allowed. We will have a campfire at the start/finish if weather allows. Pacers are permitted after the 10 hr mark has passed (7 pm). Please share the space and do not set up sleeping tents along the edge of the course but rather behind your aid canopies. If you bring it with you, please pack it out; do not leave your trash at the race site. There are no rule police. Behave yourselves and be good stewards for our sport.

Awards

The top 3 male and top 3 female runners at The 25th Hour Endurance Run will receive a unique, hand-crafted award from local carver Sam Moore from Black Mountain, NC. The top m/f masters (40+) and grand masters (60+) will also earn one of these! Milestone awards will be presented to runners as they achieve milestone distances (25, 50, and 75 miles). Other special awards and giveaways to be announced soon. All runners will receive a race sweatshirt at packet pickup.

Refund Policy
