I never raced enough to get enough points to hit 1/2 even though I probably could have if I kept at it. Low quality race organizers slowly embittered me to the point of quitting racing. Oh well. I’m baaaaacccckkk!
Even though I think it took only 10 points to upgrade, residing in The Great White North, the race season is pretty short and even back in the heydays of the 90’s there wasn’t that many races available inside of a 1-2 hour drive.
Just from my personal observations, the 1/2s that I knew took one of two paths after hitting the top – they either went pro (or tried) and retired within a few years, or just kept racing at 1/2 level and are now crazy strong Masters.
