The 98th year of the Tour de France is in full cycle as competitors endure one of the the most psychologically and physically challenging athletic events in the world. The more than 2100 mile route through French countryside will be completed in just three weeks. Drawing riders and teams from around the world, competitors vie for the prestigious yellow jersey or maillot jaune, given to the rider with the fastest cumulative time.
The Tour De France has changed over the years. There are lighter bikes, thinner tires, aerodynamic helmets, and let's not forget the countless doping scandals.
However, as much as the competition has changed there are still flat tires, heartbreaking crashes, and stiff competition. And most importantly, the determination and a willingness to push the human body beyond its limits.
Take a look at the Tour De France: Now and Before.
