If you're training for long course racing I assume you want to build you r long ride to around 6 hours.

Assume you're building your long ride up to six hours throughout your base period. After you've reached the 6 hour mark do you take a number of six hour rides over a period of weeks or months or should your longest ride be a goal. In other words, should my goal be 1 six hour ride at the end of my last base period or should I reach that 6 hour mark by the second base period and then continue with those rides for the rest of the base periods?

Thanks,

Tom
