Lance is the most successful Tour rider of all time because......
1. Intense desire to succeed.
2. Incredible preparation.
3. Amazing attention to detail.
4. Increible ability to focus on all details.
5. Way above average physiology, i.e low lactic acid output, high Vo2 max,etc
6. Cutting edge equipment and tech advances.
7. Great surrounding cast. From teammates, Director (Johan) etc.
Lance may be the most focused athlete of all time. Perhaps this stems from his very real, very close brush with dying that changed him. It gave him the ability to singularly focus on getting what he wants to accomplish. Lance has surrounded himself with the top people in every aspect of the race, from bikes to cooks to massuers, etc. He meticulously controls every aspect of this race. What is wrong with that? Again, this goes back to his focus, and desire ---- which culminates in his preparation, which simply put, is better than everyone elses.
