I have never competed in any Winter Olympic type sport. I don't know anyone who does compete. Winter sports are really expensive.
I have competed in disc golf. I know a bunch of people who play. Disc golf is inexpensive - unless you have 200 disc - ok so it's not that cheap but much cheaper than winter sports. You can play dg all year long.
I think it would be much easier to be a curling/nordic combined/skeleton etc Olympic gold medalist than a disc golf champion.
