Event Information

Runners are responsible for their food and water. Volunteers will provide an aid station with drinks and snacks, but it is the responsibility of the runner to make sure they have enough food and hydration to sustain them throughout the event. This is a cup-free event and participants will need to bring their hydration systems. Littering on the course will subject you to disqualification Final results will be calculated based on the number of total laps completed by the time limit. If you are struggling at any point, race officials 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. Runners may have crew support every lap. The crew must stay in the designated area in the infield of the track near the start line. Pacers will not be allowed unless they are registered participants. Runners will be credited for .25 Miles per lap completed. Your watch will most likely show you doing 1-2 miles more than this due to the nature of track running. Please expect your watch mileage to be higher than your track mileage! Courtesy Rules: All runners have the right to the inside lane, yes even "slow" runners. You're fast, congratulations. It's your duty to run around other runners safely! If you are in the inside of lane 1, stay as far inside as possible so other runners may pass you also while utilizing lane 1. In other words don't run in the middle of lane 1. Finally, since runners will need to be able to easily pass other runners, please do not buddy up and run/walk side by side in the inside lanes and create a wall. Running should be done single file. If you need to buddy up, please take it to an outside lane (5 or 6). Runners will be allowed to bring gear, nutrition, etc. for their own "pit area". You can set up a small tent but absolutely NO TENT STAKES. This is a turf venue so you will need to weigh down any tents.
