Arena has been announced as a technical sponsor of the Rome International Marathon, which will be run on April 7, in Italy's capital city. The event, now in its 25th year, is one of the world's best known long-distance running events, due to the special appeal of its route. In addition to kitting out the staff and volunteers in charge of the race, Arena has developed the official T-shirt for the event, in black with bright orange inserts on the shoulders.
