i was a soccer player and in junior high every 6 weeks we did a set of tests, including in offseason from track. i would win the 40 and shuttle run, and be top 5 in the mile sandwiched among the distance team, 505 or so, no distance work as such, but soccer practice and games.
we were supposed to do 1 mile as part of the presidential test in frosh PE but my friend and i were scouted off the 50 yard dash results and sent to track period.
based on being top 5 junior high the distance guys were always trying to get me out for XC. i finally caved soph HS. i could easily run well sub 5 with actual distance training. my issue was as someone who normally did sprints or hurdles i could never get the pacing right. couple times i was like in first place in the whole race running mile 1 sub 5, and felt good for maybe a mile after that.
the other "naturals" IMO would be hoops players. our best 2 distance guys, d1 type speed, were varsity hoops. they do more conditioning work than even soccer does. you need lungs to stay on the court and not need a sub. you have to try and beat people with bursts and outjump them. you have to track back and guard someone on defense.
soccer has that too. that to me is where it lies, needing to be able to summon speed when tired, and to drag your butt back on defense all game. i could pace for crap but we are chosen for speed and endurance -- kids who can't stay with speed of play or are out of shape get weeded out -- and we're gritty by nature. if i quit fighting with a minute left you maybe find a way to beat me.
