@vipnata Good! I don't really know much about athletes.
The first search, I send the photo to search on Google Images, but, as it is pixelated, sometimes it works.
If it doesn't work, I look for some detail in the photo to search, an emblem on the clothes, some type of equipment that you are using, then I start the search, it also often takes hours.
When luck helps, I find a similar image and try to find it.
Have a nice week
