There are some athletic scholarships at Oxford and Cambridge, but they're not at all mainstream in the way athletics seems to be in the US.
There's also Track and Field, which generally you can do cheaply and anywhere.
After that you start getting restrictions on where you can do them and what it costs to do them. So obvioulsy they'll be done more by the "elite"
Other college sports:
Hockey: Quite expensive gear, ice time. Maybe in Canada? In the US football pays for all the gear, in much of the US you buy your own hockey gear for like $1k.
Tennis: These days maybe not as elite, can be quite accessible, but historically quite elite.
Golf: Golf actually has a huge blue collar contingent, but still seems pretty elite.
Swimming: You need a pool, you need heat or an indoor pool, likely regionally dependent on elite vs accessible.
Wrestling: you can do this anywhere, I never see it in a public park. Well, most of the time.
Field Hockey / Lacross: These are new england elite sports for the most part. Wish I played LAX in HS actually, would have been less fat.
Skiing: Access, expensive equipment. Heck the northeast doesn't even have good ski slopes.
Sailing/Equestrian: lol, $$$$ for the "vehicle" and you need land or access to a large body of water, both quite spendy.
In other words, it doesn't get expensive until after your kid has really decided they want to do it.
