100 mile live runner tracking is made possible by our friends at UltraLive. Runner tracking is for entertainment purposes only. The link to the live tracking can be found below. 100 mile runners are tracked as they come into each aid station. Our HAM Radio volunteers and aid station volunteers work together to record each runners bib number, the HAM radio volunteers then call in bib numbers to Net Control (our communications command center), runner tracking volunteers then transcribe information from the HAM Radio volunteers tracking sheets into UltraLive and that is the information that is displayed. Please note that that at times, runners times may be batched and may not be accurate to the minute. Should there be an emergency, emergency communications will be prioritized and live runner tracking reporting may be discontinued for a time.
