A 7s game only lasts for a total of 14 minutes. A standard Association Football match lasts 90 minutes. Not really much standard for comparison -- it's the equivilent of comparing a 100 metre sprint to a marathon.
if 7's was played for 90 minutes then it would easily have more but because its only 14 its not as long so i think soccer wins this, but 15's beats soccer :P
I play rugby 15s and soccer rugby has way more then soccer
7's by far....
I think on average a professional footballer runs somewhere near 12 km in a game. Dependent on position and willingness I'd add. So for an amateur player I'd be guessing around 8-12km. As the other answerer said. Sevens rugby is more like a sprint and a full length match of football is more like a marathon. Both require different fitness regimes if you're looking to play properly.
