As outfield players buzz around the pitch, goalkeepers are penned in their penalty box waiting to save shots, collect crosses and sprint off their line to greet would-be goalscorers.
Without the mileage, goalkeepers need to keep a close eye on what they eat. Get too heavy and they will find it that bit harder to fling their body weight across goal to reach a shot.
Goalkeepers have to be light on their feet and alert, which is why Blackburn goalkeeper Paul Robinson tailors his pre-match meal for the demands of his position.
"I don't like to eat on the morning of a game. I like to go into the game feeling as empty and as light as possible," the former England goalkeeper told FFT.
"I'll just have two or three double expressos, a little bit of fruit and maybe a handful of nuts."
