I was wondering if Anakin Skywalker really is the only human who can race pods.. I find it hard to believe considering the sheer number of populated worlds. Is there any mention of any other human, Force-Sensitive or not, who can race pods? I would be okay with a Legends answer..
According to the novelisation of Revenge of the Sith he wasn't the only human to ever start a race, but he was certainly the only human to successfully complete one. Note that over two-thirds of the racers in Anakin's race crashed and several died.
A few wings of droid fighters didn’t much scare a man who’d been a Podracer since he was six, and had won the Boonta Cup at nine. Who was, in fact, the only human to ever finish a Podrace, let alone win one.
Notably, this section of the book is told from the perspective of the omniscient narrator rather than Anakin's own limited view.
