I think too many young, talented riders tend to sit in the pack too long and simply roll over the line with 50 other riders. More than often they have simply ridden with the pack for the entire length of the race. And who can blame them? I mean, it's safe in the pack - you can hide. And just watch any ProTour event, many high profile riders tend to ride across the line in a sea of other riders. So wouldn't the Juniors do the same thing?
Maybe it's ok at the ProTour level, at that stage in the game many considerations come into play. Considerations that does not exist for young, promising Juniors. But I can promise you one thing; the riders you see roll across the line on a ProTour team did not get there by hiding in the pack as a Junior. So why do we see so many riders playing it "safe", rather than taking a chance and going for it? Is it because it's better to end up number 20, rather than maybe giving it an honest shot but blowing up and not finishing?
I believe it should not be about the results, but what happened during the race. Juniors develop by racing aggressively. By daring to go in breaks, by creating opportunities, not waiting for them to be created by others. Juniors need to risk individual race results in order to grow and learn. How can you discover the strength of your legs if you don't dare to push it a little harder? Not to mention what you can learn in terms of tactics.
So, in short - I'd like to see more aggressiveness from Juniors. Think Vinokurov during the 2005 Tour. This mind-set is just as much the responsibility of anyone involved with and working on developing talents. This is encouraging and rewarding aggressive riders. The change should happen from club level up to national level.
If any Juniors or anyone working with Juniors have any input, please post it. :)
