About
Frosty Five: 5K Costume Fun Run takes place in San Antonio, Texas, on December 20, 2026, with the 5K costume fun run (3.1 miles) starting at 8:00 a.m. It is a community race open to all ages, with holiday costumes as the theme, and you can enter either the timed or the untimed option. Registration includes a medal and a long-sleeve shirt. The event supports Street2Feet, a nonprofit that works with people experiencing homelessness through running programs.
Having a timed and an untimed entry side by side is genuinely useful: pick timed if you want a result to compare against your last 5K, untimed if you would rather run with a friend or in a costume that is not built for speed. Either way, three weeks of running 20 to 30 minutes, three days a week, will carry you through the distance without trouble.
