I’ve spent the last nine years working hard towards this moment and have had an almost sleepless month preparing for this race, the first race in history where a robot has competed at the olympics. My robot.

Back then, I could only dream of the Olympics but look at me now standing here. The gun goes off which brings me back to reality, leaving a ringing sound in my ears.
