Putting on ultra-distance trail-running races in remote locations with minimal cellular phone coverage is challenging to say the least. In order to maintain the highest level of safety for all of our runners, volunteers and staff we rely on Armature Radio Operators also known as HAM radio operators. Each one of our events is staffed with an army of experienced radio operators who provide communications, runner tracking, facilitate logistics and coordinate emergency response. Without this dedicated group of often unheard / unseen VOLUNTEERS we would not be able to host our events in the safe and organized manner that we do today. If you are an Armature Radio Operator and would like to learn more about working with the Zumbro Endurance Run, please CONTACT US and we will forward your information on to and put you in touch with the Armature Radio Personnel Coordinator for the race.
