Welcome to the Gray Mud Run! We thank you for supporting the National Brain Tumor Society’s efforts to find a cure for brain tumors and improve the quality of life and treatment options for those living with a Brain Tumor. This is the first event established in Northern New Jersey to serve the brain tumor community (and the first of it’s kind for NBTS)… And we are so excited to be here!
The Gray Mud Run is a family friendly fun run and muddy obstacle course. The Adult course is a 5K and the Kids course is a 3K.
This event was inspired by the life and brain tumor journey of Lindsay Gray. Beloved daughter, sister, friend and fearless NJ State Trooper. We are working together with the NJ State Troopers to reach the entire Tri-State area brain tumor community with this event and look forward to having a remarkable turn out!
