Lace up for one of America's most storied half-marathons, taking place in early May 2026 as Kansas City hosts this 53rd running—and don't miss out if you can't be there in person, since a virtual option lets you join runners worldwide. You'll be part of a massive gathering celebrating this city's oldest road race with awesome perks like special finisher's medals, race gear, live entertainment along the course, and a celebratory finish line with food and drinks. Just note the earlier May date this year due to FIFA World Cup events happening in Kansas City.
