Race Info
The Firenze Marathon starts and finishes in Piazza del Duomo, in the heart of Florence. The flat course crosses the Arno River, passes the Ponte Vecchio, and loops through Cascine Park and the Campo di Marte sports district before returning to the cathedral square. First run in 1984, it is one of Italy's largest marathons and an AIMS/World Athletics Label race; the 2025 edition set a participation record with more than 10,000 finishers. Estra, a Tuscan energy company, has been the title sponsor since the 2024 edition.
