Hikaru Nakamura the chess player regular runs marathons and has a pretty good time.
Being good at both chess and running is basically the ability to pick up things fast and have the drive and discipline to continue learning at a craft so you get better. Since Hikaru is a chess genius and has the discipline to maintain it especially in his competitive field, he would be able to also apply it to get good at other things. He won't outrun Kenyans but it shows why people who are "geniuses" are not all idiot savants like stereotyped.
Likewise if you want to enter the D1 football program or whatever at college, you have to be disciplined. No way around it. We constantly hear about the failed jocks who got cut from the team before they even made it to college. So if you were able to play for college, you must be damned disciplined, competitive and probably very quick on the feet. Team sports mean a lot of teamwork too. You don't have time to bully nerds, you have a game to win because if not then there goes your scholarship. These sort of skills are vital for most jobs since there are only a few jobs that need quant trading or something.
Mao wrote an entire essay on why fitness is important. When you think about it, all those "nerds" in china who were forced to actually use their hands to work the fields during the cultural revolution were able to come up with great ideas that helped China become the modern entity it is today. In contrast, today a lot of smart nerds today in China do not show the same drive or brilliance the older generation had because they never needed to use their hands.
