Haute Route Asheville 2019

Hi there from Ireland in lockdown! I thought it best to pose my question here as it relates to long/multi-Grand Fondos.
Since last November, I’ve been training with the excellent TR for Haute Route Alps 2020 Haute Route Alpswhich (hopefully) takes place over 7 days in late August, 800km, 20,000 metre plus total elevation. I am working my way through the Plan Builder and due to complete Rolling Road Race MV in 2 weeks’ time. My 2 questions are:

  1. Next up in my training schedule is General Build MV and I wonder should I change this to Sustained Build MV.
  2. The final phase as per the Plan Builder is Rolling Road Race again MV and I am looking for suggestions on whether I should alter this to Century MV? This may well be splitting hairs and there probably is no simple or ‘right’ answer. I am 57 with FTP/kg of 3.2 which hopefully will show improvement after the ramp test in 2 weeks. Many thanks.
