In keeping with the theme of a slow, sequential race preview, here's a great video of Le Trouee d'Arenberg: showing all the various challenges a rider faces just getting through it. My favorite part is where the solo rider loses momentum and looks like he's about to keel over. These are some of the top pros in the world, and this is no more than a slight uphill grade. Anyway...
