Lost Marbles
When you're in it to win it on a sunny track day, sanity's gonna take a back seat (if you have one), so losing your marbles is the only option. But, don't worry: you'll find more along the way. At least that first-place trophy will make the many hours of buffing them out more rewarding.
This is one of our ongoing themes, so stay tuned for more.
Ladies version here.
