Up to Half a Minute
A holdover from the days before race radios the race organization provides a motorcycle with a chalkboard who will ride between each group on the road showing them the time gaps. This is so low tech that it is done with a stop watch and written with chalk on a traditional chalkboard. Some races have gone to the dry erase board which will work a little better in the rain. This is the break with Thor Hushovd (BMC), Simon Geraints (Sky) and now with Tom Boonen (OPQS) who have the power to stay away to the finish.
