All Day Running Co. Clearwater Marathon & Running Festival

All Day Running Co. Clearwater Marathon & Running Festival spans two days in Clearwater, Florida, on January 30-31, 2027. The 5K and a kids fun run open the festival on the Saturday. Sunday carries the longer events: a 50K ultra, the marathon (26.2 miles), the half marathon (13.1 miles) and a two person half marathon relay. Start times for the individual races are not published.

A weekend that stretches from a kids race to a 50K lets a group pick very different days out and still travel together. The relay is the easiest way into half marathon distance if you are not ready to run all 13.1 alone, since each partner covers roughly six and a half miles. For the marathon, plan a sixteen week build with a weekly long run; for the 50K, the same build with more time on your feet and a proper rehearsal of your race day fueling.
