Trail Etiquette
Remember to always remain on designed trails, no short cutting.
Headphones are not permitted.
E Bikes are not permitted.
This course includes some legit single track. If you are fast and attempting to pass, please alert the rider in front of you before flying past them. Likewise, if you hear a rider approaching you from behind, attempt to find a spot to allow the pass.
As a general rule, when passing a rider, announce, “on your left.” Remain in control and respect the other participants.
Everyone is after the same goal here so let’s be respectful of each other’s races and have fun.
Pets
For the safety of all runners, no pets are allowed on-course at the night races. Any pets at the race must be on a leash at all times, respect park rules, and be supervised.
