“From” is doing some lifting, maybe not heavy, and, no, that’s not how international sports works.
I’m not going to list some famous athletes who have raced for a nation they are not from: you will be able to.
I depreciate swapping nations but athletes have, at senior level, maybe 20 years and lives/circumstances change.
Please briefly state your criteria you think should apply for eligibility to race for a country/nation. I’ll offer a framework (delete bullets as necessary)
- Birth
- Parent
- Grandparent (personally I would not include this)
- Residence (define in years, and I would exclude time at uni, ie with a home base elsewhere)
