We are introducing two little technical innovations at the Rome Marathon 2013. All runners will have the opportunity to have their name printed free of cost on the bib. Along with the engraved medal, this is a nice memorabilia. Even more interesting, the Rome Marathon 2013 will be timed with disposable chips. Lighter bibs and no hassle to return the chip at the end of the race - and nothing will be charged for unreturned chips.
