I’m following the Masters Low Volume Base I, II, and III with 3 rides total per week and 2 intensity days per week. It is basically 1 hour sweet spot on tuesday, 1 hour endurance on thursday, and 1.5 hour threshold over unders on saturday. I started strength training consistently 4 months ago and underestimated the added stress the squats and lunges would add. But I’m now getting to the point where I feel pretty comfortable with the 200tss + leg strength session per week. I like the rhythm of the plan I’m on but I’m pretty time crunched (full time job, young kids, etc….) so all of my riding is done between 5:30 a.m. and 7 a.m. and I’m not a morning person. The 1.5 hour threshold workout on saturday just means I get less sleep and my question is about shortening the saturday threshold workout and adding an endurance ride on Sunday.
Question: What is better….A 1.5 hour Saturday threshold over under workout like Nellis Wash (which bookend the threshold work with 2 x 18 minute of z2). Or a 1 hour Saturday threshold over under workout like Coe (which is the same as Nellis Wash but without the book ended z2) AND a 1 hour endurance ride on sunday? I can see benifits to both training wise, but curious what more knowledgable people think.
The first photo below is my prescribed training, and the second photo, would be the proposed alternative. This would allow me more riding time per week, and slightly more tss and the same threshold work, but lacks the endurance work during threshold sessions. I plan on repeating this plan throughout the winter for base training so I would repeat whatever option is optimal week over week. Thoughts?
