@mrstbw That mileage would have been doable for S&S but a lot tougher with RoP and TTC.
The light, medium, and heavy pressing days are essential to RoP, so I think I would have kept those and opted for running on my two variety days, with another run on an off day, and maybe a recovery run later in the day after the light pressing session (for four runs total). I would have made an effort to take at least one full day off to recover and made all of my runs super easy.
TTC is where it gets really tricky because the rep pyramids are designed to push you to your limits. Do you follow
John Parker on IG? He's an SFG who hikes a lot, and I believe he turned TTC into a 2x per week, eight-week program so he could maintain his miles. I probably would have done something along those lines.
With both RoP and TTC, my goal was to build strength, and I don't think I would have made the same gains if I was trying to maintain 20+ miles a week. Hope that helps!
