What to do next.... After FTP Builder Plan

Hi guys n gals,

I am new to zwift & indoor training/riding. I started my zwift career by doing the FTP builder plan and have just completed it. I didn’t do an FTP test before, but found it to be a good workout.

I intend to do the FTP test next and then ideally back into another training plan, but I am a little unsure what to do next.

Ideally each workout needs to be no longer than an hour (the odd one at 1:10-1:15 is ok) and no more than 4 a week. I actually ride mountain bikes when riding in the real world, but I see any zwifting will benefit me with fitness and strength.

So can anyone recommend which plan to take on next please!

I appreciate any feedback received!

This is my GO TO: 4wk FTP Booster.

I do it over about 6 weeks, because I race once a week and Lead a group ride on another day.

They are about a hour long.

excellent, thanks for the recommendation!
