Fiery Gizzard

The Fiery Gizzard Run features a half and full marathon distance of racing on one of the Top 25 Trails in the US. Marathon runners will complete the entire trail twice in an out-and-back format, starting and ending at The Grundy Forest end. Half marathon runners will complete one full traverse of the trail. The course provides beautiful waterfalls, stunning rock formations, and overlooks with views for miles. The trail is mostly flat ridgeline running with several steep dips into gorges. These descents are quite technical and require focus on your footing. Although the trail is very well-maintained, there are a few spots that could be dangerous, so please read the race layout carefully and listen to all directions from the RD at the start of the race. The race layout will be sent via email approximately one week from race date.

Aid Stations

Aid Stations
Due to limited access on the Fiery Gizzard trail, aid stations will be further apart than our typical events. You can expect 6-8 miles in between aid, so be sure to carry sufficient water and nutrition for these stretches.

We are known for having great aid stations, stocked with snacks, Spring Energy gels, water, and electrolytes. Please note that due to COVID-19, typical aid station fare may be limited, and we will ask for your patience and understanding as we navigate hosting races during a global pandemic.

We will not be providing cups, so you must carry your own water container.

Medical Care/First Aid
**Important: Trail running is dangerous and can lead to injuries or death. There are portions of this trail which will require your focus and patience. If you’re willing to accept these risks and still be humble, then we welcome you with open arms (this is not meant to dissuade you, only to be upfront and honest). Please note that we do not have a medical staff, but can provide you with basic first-aid once we get to you in the field. In short, you’re on your own and responsible for your safety. In the event of a rescue, runners will incur all costs of such a rescue from the state. However, we will have basic first aid sweepers that can help you out if you need an extra hand.

HardRUCK

We are thrilled to once again host a ruck division for each race. For the uninitiated, rucking is typically described as walking/hiking with a weighted pack. The activity gets its name from “rucksacks,” which is military-speak for “backpack.”

Per typical ruck standards, the weight requirement is determined by body weight:
Over 150lb – 20lb dry
Under 150lb – 10lb dry

Please plan to weigh in 30 minutes prior to the event start.

Weight must be in the form of a steel ruck plate, weight vest blocks, bumper plates or other items which have the weight clearly stamped. Removal of plates or reduction of weight during the event is not authorized. Honor system applies. Do the right thing.
