I started getting into 6-Day Racing after learning how to race a proper Madison... now I follow 'em, have raced against a handful of Euro 6-day racers brought to the US for prestige, and watch livestreams.

The Amsterdam Six livestream even has English commentating, so, it's got that going for it.
Enjoy!
