Full distance tri and plan builder question

After going through the full Tri plans a few times and some ventures into some other other plans I’m now building towards another IM.
I’ve gone through base and build according to the plan builder, which has now inserted 5 weeks of Base, from the beginning. While I see some of the benefits of going back and building more base. I’m having trouble with seeing how dropping so much of both volume and intensity in all disciplines can be beneficial. Specially on the run, but also the swim, and then jumping into the specialty phase with a pretty big jump from base. Should I stay the course or work around it some how?

+1 for Full IM training questions with plan builder … I’m doing the full distance IM plan, currently in build phase. My event has been cancelled for the year but still wanted to go through build and speciality plan as I am new to TR and interval training so want to learn how My body and systems will cope.

  1. I had a VO2max bike session Monday morning and the run instructions for the afternoon were vo2max intervals as well. I’m not sure what the best way to structure run sessions is accounting for all the bike structured training. Isn’t it the same system that cycling intervals call on? Should run training be all bases or intervals? How best can they be interspersed between the specific bike intervals?
  2. I’ve found that I can destroy every type of interval, in most cases able to up the intensity one or two percent but the 3 minute vo2max intervals completely destroy me. I can only manage a couple before dropping the intensity 5-8 percent. I did 2 minute Interval session Which I was able to get through at 100%. What is the best way to build up my weakness here? Do lower intensity 3 minute intervals or full intensity 2 minute intervals until my body catches up? Or a mix of the two?

Thanks for the great product and FYI, your support team is 5 star!!


  1. Hmm in the same day you have VO2max for bike and run? As far as I see my IM plan the bike is on Monday and run on Tuesday. Doing both VO2max sessions in one day sounds like overkill.
  2. Do you read the description of VO2max sessions? Like the instructions during a workout? They explain why someone can feel fine with VO2max and someone not and simply as it is it will take time to accomodate to those sessions. In my case I’m pretty good on 3mins and I almost always has to up intensity - as Coach Chad explains during a session if you feel fine up the session, if not down but no less than 110% FTP because then it’s something else. Just read the instruction :slight_smile:
