What you get

By the end of 12 weeks

Sweet spot work at racing load, 550 to 750 TSS a week
Twelve weeks of progressive overload into your season
Ridable on any platform and in any discipline — indoors or out
Six sessions a week, short midweek and longer at the weekend
Core and hip strength routines that make the power you build usable

The top tier of the Sweet Spot line. Twelve weeks of sub-threshold work at a load that only makes sense if you are racing at the front.

Sweet Spot or Zwift Base?

Zwift Base is built around riding in Zwift and tops out at 850 TSS a week. Sweet Spot Base is built around the method, rides anywhere, and tops out at 750 — less total load, more of it spent near threshold.

If your winter is happening in Zwift regardless, take Z.B.3. If you want base you can take outdoors, or you ride more than one discipline, take this.

Before you commit a winter to sub-threshold work, sweet spot vs zone 2 for aerobic capacity covers what it is actually building and where long steady riding still wins.

Who this plan is for

Cat 1/2 racers, riders with five or more seasons of structured training, or anyone winning in their age group. Around 8.6 hours a week across six sessions — a real commitment through a winter.

How the load builds

The plan opens at roughly 550 TSS a week and finishes at 750, with progressive overload block by block. Weekday sessions stay short; the volume goes on the weekend. Interval duration and intensity change throughout the twelve weeks.

Core and hip strength and stability routines run alongside the bike work.

What you get

Every session as a structured workout file, exportable to Zwift, Garmin or Wahoo

FAQ

Questions about this plan

Do I need a power meter for this plan?

A power meter makes the targets precise, but it is not required. Every session lists heart rate and perceived-effort targets alongside the power target.

Does it sync with Zwift, Garmin and Wahoo?

Yes. Every workout is a structured file. Connect TrainingPeaks to Zwift and the day's session appears in your workout list; connect Garmin or Wahoo and it pushes to your head unit.

Do I need TrainingPeaks Premium?

No. A free TrainingPeaks account is enough to buy this plan and follow every workout. Premium adds deeper analysis but nothing this plan depends on.

What if I miss a session or a week?

Shift the remaining plan forward on your TrainingPeaks calendar and carry on. The plan is built in blocks, so a missed session will not break the progression.

What if the plan turns out to be wrong for me?

Plans are covered by the TrainingPeaks refund policy. With the author's approval, a plan can be exchanged for another of equal value from the same author. Refund requests must be made in writing to TrainingPeaks within 24 hours of purchase with a detailed explanation, and are assessed case by case. If you are unsure this plan fits, get in touch before you buy and we will point you at the right one.
