Daytona 100 Ultramarathon

Daytona 100 Ultramarathon is an ultrarunning event based in Daytona Beach, Florida on December 12, 2026, with three distances on offer: the Daytona 100 at 100 miles (160.9 km), the Daytona 50 Mile at 80.5 km, and the Daytona 50K at 31 miles. These are the classic ultra steps, and the choice between them is really a choice about how much of the night you want to spend moving. Start times aren't listed, so check the event's own schedule before you plan your crew logistics.

The 50K is the sensible first ultra for a runner already comfortable with the marathon, and it can be approached much like a long, patient road race. The 50-miler and the 100 are different animals: they require months of back-to-back long runs, a rehearsed fueling plan you can actually stomach late in the race, and practice walking hills and eating on the move. Twenty to twenty-four weeks of specific training, with your longest efforts measured in hours rather than miles, is the realistic frame for the two longest distances.
