Rudolf Red Nose Run

Rudolf Red Nose Run is a 5K in Key West, Florida, on December 12, 2026, staged by the Southernmost Runners. The single format is the A Positive Step 5K Run/Walk, starting at 8:00 a.m., so you can cover the 3.1 miles at race pace or at a walking pace, whichever suits you. Its holiday name and its December date place it squarely in the festive end-of-year calendar at the southern tip of the Florida Keys.

A 5K in Key West in December means mild conditions and an easy excuse to combine a race with a long weekend. The run/walk format welcomes beginners and families, while faster runners can use it as a short, sharp effort between longer training blocks. If this is your first 5K, four to six weeks of three easy runs a week with a few gentle pickups will have you ready; if you are chasing a time, keep the days before light and go out at a pace you can hold for the full distance.
