What you get

By the end of 12 weeks

Sweet spot work that returns more fitness per hour than steady riding
A build from 380 to 610 TSS a week over twelve weeks
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 middle tier of the Sweet Spot line — twelve weeks of work pitched just below threshold, at a load that assumes you have done this before.

Sweet Spot or Zwift Base?

Zwift Base is built around riding in Zwift. Sweet Spot Base is built around the method, and works in any discipline, indoors or out. Both export to Zwift, Garmin and Wahoo — the question is whether you want a Zwift-native winter or the most time-efficient base you can ride anywhere.

Note this plan finishes higher than its Zwift Base counterpart: 610 TSS a week against 550. Sweet spot work packs more stimulus into the hour, and the ceiling reflects that.

Why it packs more in: sweet spot vs zone 2 for aerobic capacity compares the two hour for hour.

Who this plan is for

Cat 3/4 racers, riders with three or more seasons of structured training, or anyone placing in the top 25% of their age group. Around 6.9 hours a week across six sessions.

How the load builds

The plan opens at roughly 380 TSS a week and finishes at 610, with progressive overload block by block. Weekday sessions stay short to fit a working week; the longer rides sit on the weekend. Interval duration and intensity vary throughout, which keeps a six-session week from turning into a grind.

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.
