The 42nd edition of the Half Marathon Firenze returns on 29 March 2026, organized by UISP Firenze and supported by a large volunteer network. Runners tackle a chip-timed 21.097 km course that threads through Florence’s historic streets and riverfront (start/finish and program details are published on the event site). Alongside the traditional half, the event offers the Mezzaperuno pair relay format and shorter non-competitive routes (including a 10.5 km option on some editions), making the weekend accessible to a wide range of athletes and visiting runners. The race is a highlight of Florence’s spring running calendar, combining competitive performance, tourism-friendly routes past monuments, and festival-style race-village services.
