Field hockey – ca 5 miles (defenders run less)
Football – ca 7 miles (Midfielders run around 8.5, attacking full backs also, GK and centre halves substantially less). Referees run further than players. But game is 90 mins vs 60 in hockey, so similar intensity, just for longer.
Rugby – front rowers ca 2.5 miles, scrum half around 4.5 miles (most of which while also attempting to ref the game). Lots of ball not in play time in rugby, so a lot is done at full speed and a lot at no speed.
