Firenze Marathon would like to communicate that due to a gas leak at km 40 along the race route of today’s marathon, in order participants’ safety, in agreement with local police and firefighters it was necessary to make a slight change to the route. Exactly 600 meters were ‘cut’ near Via Lungarno Vespucci and was blocked after the first 60 runners therefore all qualifications at the national and international level will need to be approved by the Italian Athletics Federation.
