La Natalina is a 10 km run marking the start of the Christmas season, held in early December in the Argentario area, with an event in Orbetello. It is intended for both regular runners and competitive athletes, with the race day focused on a short, direct distance instead of an ultra or trail format.
The Orbetello course follows scenic roads through the natural landscapes near Argentario. Records also indicate a Monterotondo edition organized by Atletica Monterotondo, which drew about 500 participants, including many from Purosangue Athletics Club. This route was hilly with consistent ascents and descents. Luca Filipponi finished third overall in 31:27, and Purosangue runners secured multiple category awards.
