^ you don't even have to give it up. Just stop focusing on it. Set more immediate, reachable goals, and the rest will take care of itself.
The fact that you haven't gotten off to as fast a start as you'd hoped doesn't mean you can't be successful as a bike racer, and have fun at it. Where you end up will be determined down the road.
Enjoy the here and now.
