This is how we would typically set up a training cycle for our athletes:
3 week foundation plan
10 week resistance training program (weight training)
18 weeks of sweet spot training (sweet spot 1, 2 and 3)
6 wees interval training (road race interval or Fondo plan for you)
Event or Goal.
So it sort of depends on when your events are. It appears you have already done several weeks of base training so would likely start an advance base program like sweet spot 3 which starts to introduce some intensity. Then you would do a specific 6 week interval plan. Maybe our Fondo plan to prepare for a 100 mile ride. But this would be 12 weeks from now.
If you want more time between I would highly recommend our sweet spot 4 plan! This can be another way to get mix in aerobic training and intervals before starting the 6 week Fondo plan. With have done so much base and sweet spot training getting this polarized training can be super beneficial to you.
So I would recommend Sweet spot 3 plan. Then go to sweet spot 4. Then do our Fondo plan. That would set you up to do your 100 mile ride in 18 weeks.
Then to prepare for your rolling hill race I would recommend doing another round of sweet spot training to build your base back up and then our road race interval plan.
And as a note we do have our full offseason plan which gives you the foundation plan, resistance training, and 18 weeks of sweet spot. But also we do have our 18 weeks of sweet spot training which is sweet spot 1, 2 and 3. There is good value to buying the bundles.
