Ham Radio for Marathon Organizers: Event Communications Guide

Coordinating 26.2 Miles of Chaos — Over Radio
Marathons are the classic case where ham radio shines. Thousands of runners over 26 miles, hundreds of volunteers, medical teams — all coordinated by volunteer ham operators.
Why Marathons Depend on Ham Radio
- Cell towers overload: 10,000 spectators crash networks. Radio does not care.
- Instant broadcast: One transmission reaches every station on the course
- Medical emergencies: A collapsed runner at mile 18 gets help in minutes
