KEYS100 Ultramarathon
The KEYS100 Ultramarathon is a point-to-point running event held across the chain of islands in the Florida Keys. Participants traverse the Florida Keys Overseas Heritage Trail along the Overseas Highway (US #1), finishing in Key West at Higgs Beach. The course consists of paved surfaces, with approximately 75% on bike paths or sidewalks and the remaining portion on the road shoulder facing traffic.
Available distances and categories include:
- 100 Mile Individual Ultra: From Key Largo Community Park to Key West with 32 hours finish time.
- 100 Mile Team Relay: Teams of up to six runners following the same 100 mile route.
- 50 Mile Individual Ultra: From Marathon Garden Club to Key West with 20 hours finish time.
- 50 Mile Team Relay: Teams of up to three runners starting from Marathon.
- 50 Kilometer Individual Ultra: From Big Pine Key to Key West with 12 hours finish time.
This event requires participants to be self-sufficient as there are no aid stations provided along the route. Individual runners are required to have a support crew to manage their food, water, and ice. Relay teams manage their own strategy, including rotation order and distance for each runner, and must carry all necessary supplies in their vehicle. The route passes through a sub-tropical environment surrounded by the Atlantic Ocean and the Gulf of Mexico. Visit the organization's website for the most recent information.
