Katelyn Tuohy is treated as if she is a world beater on LETSRUN. She is very good of course but she isn't that special. If you are old enough, you might remember Zola Budd (now Pieterse) who in 1985, at the age of 19, ran 3:59, 8:28, and 14:48. She was also a two time world cross country champion. And she did it all in bare feet (see video of her 1985 World 5,000 meters record - it was considered a world's best because women were still not running 5,000 meters).
Katelyn Tuohy has a long way to go. She might get there but she sure as couldn't beat a 19 year old bare foot Budd. We'll see where she ends up.
