For me, I'd say I'm mostly a Goku. I run hard and throw in more surges than I probably should, which is kind of like how Goku went up to a Kaioken x4 even though King Kai told him not to go above a Kaioken x2. I always make sure I finish with a bang and leave nothing on the course, regardless of any other upcoming races, like how Goku almost dies (or does die) in like every fight. But also like Goku, I try to make everything in my training as fun and lighthearted as possible.
And also much like Goku, I perform well above my expected ability. I'm not built like your typical distance runner, but still do pretty well. Goku was only a 3rd class Saiyan warrior but still did a number on Vegeta and eventually became a Super Saiyan.
What about everyone else? Any Vegetas out there? Any Krillins? Yamchas? Yajirobis?
