The marathon starts in Piazza Duomo at 8:30, with start boxes assigned from the personal best you declare at registration. Water, tea and salts are served every 5 km, with fruit and bars added from 15 km. Free pacers cover finish times from 2:55 to 6:00, and a broom service takes runners who drop out to Piazza Santa Maria Novella. Entry is capped, and competitive runners need an athletics federation licence or an Italian RunCard with a medical certificate. A 10K runs the same day on part of the marathon route.
