Hi, a few of us are heading to Italy next week to watch the Giro stage 18 (time trial) & 19 (stelvio stage). Having not been out before, I am keen to know if the roads will be open in the morning before these stages to cycle the course? I am assuming the mountain roads on stage 19 will be open for bikes up to when any 'caravan' goes through? But what about the time trial course? Teams often ride the course in the morning to check it out - are the public allowed on as well? Any help would be greatly appreciated, many thanks!
