I've been around the sport for several years, including those at the highest level. Long story short:
Sport is entertainment. Period. And it's as brutal as the entertainment industry.
Track cycling is not a "big money" sport...to say the least. So, all you have to gain from this is glory...but glory don't pay the bills.
If you have the work ethic to become a top athlete (which is seems you do), apply that work ethic to your education and professional training, and you'll be guaranteed success.
