From the Organizer
Walkers & kids welcome for the 5K! Last year was such a success, we are doing it again! Castle Air Force Base is no stranger to a 5K/10K run but this race includes a run through Castle Air Museum. Once again, participants will have the opportunity to run amongst the many incredible aircraft of museum including fighter jets, bombers, and aircraft of all shapes and sizes. Directly following the run we will be a vendor village and open taps at the Tarmac Tap Room. Our goal is to connect the population of the central valley with health and wellness services. Together we can improve our community, together we can Raz' some hell with the goal of Raz'N Health for not only ourselves but for our entire community.
