"Ultra Sports, LLC" produces and directs very long-distance running races.  KEYS100 is a 100-mile point-to-point running race from Key Largo to Key West.  Both individuals and teams compete.  There is also a 50-mile option from Marathon to Key West for individuals and teams, and a 50-kilometer individual race from Big Pine Key to Key West.    All races finish at Higgs Beach on the Atlantic Ocean in Key West.

Important note to individual runners:  Each runner MUST have their own support crew in 2022; NO CREW SHARING, although possible exceptions will be considered for two runners who can demonstrate that they have previously shared a crew AND who have obtained specific approval of the exception from the Race Director.  There will be no aid stations or water stops along the route.  The individual runner's crew will leap-frog their runner along the course, stopping every few miles at approved locations only to provide the runner with water, food, ice, changes of clothes, gear and whatever else the runner might need during the race.  This requirement will be reviewed after the 2022 race to determine if it will remain in place in future years.
