Absolutely it depends on your goals. Do you want to do a century (just finish, don't worry about time)? Then you should concentrate on distance. Or maybe you want to do a metric and be able to finish in a certain amount of time. Then you should try to increase that average MPH. The tour was a good illustration of that. Do you want to be a climber, sprinter or over-all rider? (Ride like Richard Virenque, Robbie Mc Ewen or Lance.) Personally I wouldn't mind winning the white jersey… Oh to be 24 years old again…
