you never 'score' in cycling...unless you hook up with someone afterwards!
if you mean in cycling races..simply put you are the first one accross the finish line and you win or come second ect.
its all about the end of the race in cycling, you have to stay alert for what is happening during the race and use your head wisely and use tactics strength power intelligence to win, it is one of the most ultimate sports out there.
racing isn't for everyone though, it takes a certain kind of person to enjoy it!
but you don't know till u try!
