Am I the only idiot that cannot figure out where to find the final positions? We had a couple of silver medalists, but other than that I can't figure it out.
For some, I got the athlete's final position from the ESPN website. For others, I just googled it. Like: "final ranking for (athlete) in (sport) in rio". That worked for me anyway. That's how I got most of our final rankings.
Some categories you won't need to look up because you'll know. Like, did the sport use transportation (bike, horse, etc) or did the sport use a weapon (gun, sword, etc) or was it an ocean sport. But for the two bonus boxes related to age (under 20, and over 40), you'll need to know your athletes. I didn't know about 95% of our athletes' ages, so I used Wikipedia for that.
ETA - there are some sports that don't rank all competitors, only those who are in the top 20, top 18, etc. For those situations, if our athlete competed but didn't get ranked because they didn't get beyond semi-finals, I just listed the general ranking (like in the top 16) or I put "didn't rank, out in 1st round".
