Just finished talking to my daughter a D-1 player at a big school. A standard practice last week consisted of 40 100 yard sprints, each to be completed in under 17 seconds with a 40 second break between each sprint. If a single player missed the 17 second time mark the whole team repeated that sprint. The team ended up running over 60 sprints that morning. Trash cans were placed on the field for when players got sick. And yes this is a coach that some of the players didn't sign up for, as far as my daughter, she actually enjoys the tough training enviroment.
