The Maratonina Citta' di Busto Arsizio begins on viale Cadorna, in front of the Molini Marzoli, a former mill complex in Busto Arsizio, near Varese in Lombardy. This early-November road running event centers on a FIDAL-certified half marathon of 21.0975 km, with a non-competitive 21 km option for those seeking the same distance without racing. Shorter choices broaden the day beyond a standard half: a non-competitive 9.9 km run and a 4.4 km Family Run are available. The shorter races commence first, followed by the half marathon and the non-competitive 21 km.
The half marathon follows a single-loop course through most of Busto Arsizio's quarters, presenting the race as a city circuit rather than a simple out-and-back. The 9.9 km route largely mirrors the latter part of the 21 km course, passing through the city center. The Family Run, a walk-or-run option, aims for inclusion and participation, bringing families and casual entrants into the event village alongside club runners and half-marathon racers. Atletica San Marco organizes the race with support from the city administration. Practical arrangements include chip timing, bag drop, changing rooms, showers, aid stations, and a race pack.
