Under 2,000 runners in the marathon with less than 10 from UK.A shuttle service is available from Verona stadium to the start(in the Valpolicella wine region) not so far from lake Garda,with the first 20k out of Verona(you run by the vinyards) and a wonderful finish running into the Roman colosseum like arena(known now for operatic events) in central Verona.The weather was hot this year at 70F,so a six hour time limit can be a help,relatively flat course and no cobbles near end like the Rome marathon !.
