I was reading the following article
although I do not have a power meter I found it interesting that Joe Talks about tailoring your ride length to the types of events you will race in
"How long should optimal decoupling last relative to your race duration? There is no research to back this up, but based on experience, for cycling I use two to four hours of steady AeT exercise as the common range. For running it is one to two hours. The longer the event the longer the coupling necessary for success. If your cycling-related race duration typically falls into the two- to four-hour range simply train for that duration at AeT. For example, if you do the bike portion of a half-iron-distance triathlon or bike road race with a typical time of around 2.5 hours, then do 2.5-hour AeT bike workouts (not including warm-up and cool down). Should your race times be less than two hours (criterium bike racing and sprint- or Olympic-distance triathlon bike portions) then your AeT bike workout is two hours. If your event takes longer than four hours (Ironman-distance bike and long road races) your AeT bike workout will be four hours duration."
so my question is if my events will never be more than 2.5 hours at this point is there much point in doing 3 or 4 hour rides or longer?
I see some people posting 5+ hour rides in the training status thread, how does this help for shorter events?
would you get more out of a 5 hour ride or 2 X 2.5 hour rides if you events are only 2.5 hours?
