The start finish area will be an awesome environment – each runner can bring 2 crew members (highly recommended). There will plenty of space to set up a pop-up for you and your crew. If you are eliminated feel free to stick around, have a few beers (BYOB), and cheer other runners on! You will essentially be self-sustained. We will bring water and Proxima C Endurance Fuel - the best ultra-fuel on the planet! Check it out at .https://ultraversesupplements.com/products/proxima-c-endurance-fuel. Other than that you are on your own. Bring all your own food. No electricity will be available for crew or runners, so please plan accordingly. We will assign each individuals finishing mileage in UltraSignup. A DNF will NOT go on your record, instead it will be the total miles accumulated. We want anyone and everyone to come out and see how many miles they can run on this challenging and beautiful course! Come set a PR! Come run a few laps and join in and cheer on who's left! Our #1 goal for this race is to create an amazing trail experience where people can come out and find a new personal best. And afterwards, hang out and cheer others on as they attempt to do the same. Whether you hope to get 4.17 miles or 100 miles we want you to come out and join the fun. We will abide by all backyard rules exactly. It IS possible for ANY official Backyard race (like this one) to qualify participants for the World Championships in TN by exceptional performances earning "at-large" bids. All it takes is two great performances. In the event that someone DOES earn a spot to the Backyard World Championships from our race – from an awesome at-large performance we will provide that individual with $500 in travel expenses for the Backyard World Championships!!! The money MUST be used for expenses related to the trip. We aren’t going to hand you $500 and then you not go. We will pay for flights, gas, hotels, etc. up to $500. We will announce every time one of the spots is filled, as well as who filled it, on our FB page. No Refunds. No bib transfers. Only deferrals. No exceptions. Must be 16 to play unless accompanied by an adult for the duration. SO, welcome to THE ETERNAL DAMNATION BACKYARD! Presented by Ultraverse Supplements Endurance Evolved ultraversesupplements.com
