Is "premium membership" worth it? How much more do you get? They don't do a very good job of showing you what you have to gain from upgrading, beyond telling you that they'll grade your rides on a "suffer" scale and provide the ability to sort by age and weight.
Any premium members want to give me an idea of how they determine the "sufferage" score? Maybe tell me how much I suffered on 15/04/12. I'm pretty sure that's one score that would be counterproductive to chase much. Doing so, would probably lead to too much aerobic threashold work at the expense of strength, speed and endurance.
