Armstrong recently described the Tour as a combination of a marathon, chess and NASCAR. It is very strategic in terms of setting up riders. But at the end of the day, they must perform at the right time. No where to hide in the individual time trials. No where to hide in the final stretches of the mountain stages. That is where Armstrong excels and where is consistently wins the Tours. This year he might have won it in Stage 1 when he destroyed the field (save Dave Zabriskie) by almost a minute in a mere 20 minute time trial. No "blockers" no "conspiring" just pure athletic dominance. The key moments in every tour are the one-on-one's and Lance is the best in the world when it comes to those moments.
