An indian run is when a team (soccer, football, baseball, etc.) joggs in a single file line around a playing field field. It begins when the last person in line sprints to the front. When that person gets there, the next person at the end of the line sprints to the front of the line. This continues as the line jogs around the field. Very tiring.
Not sure if this is a racist term.
Mom - "Hi Sweetie. How was soccer practice?"
Me - "It sucked. Coach was pissed and made us do indian runs for an hour."
