Mass-start stages

The Tour directors categorise mass-start stages into 'flat', 'hilly', or 'mountain'. This affects the points awarded in the sprint classification, whether the 3 kilometer rule is operational, and the permitted disqualification time in which riders must finish (which is the winners' time plus a pre-determined percentage of that time). Time bonuses of 10, 6, and 4 seconds are awarded to the first three finishers, though this was not done from 2008 to 2014. Bonuses were previously also awarded to winners of intermediate sprints.
