FTP Builder
Eight weeks aimed squarely at threshold power, bookended by two identical 20-minute FTP tests so the result is measured rather than felt.

6-week time-crunched cycling training plan
Three sessions. Under four hours. No filler. When training time drops below four hours a week, the usual advice — build a base, then build on it — stops working, because there is not enough volume to build a base out of. The answer is to raise the density instead: fewer sessions, almost all of them with intensity in them, and no junk miles at all.
Free, with no trial. Pick a start date and your training days; the sessions land on your own calendar. Switch or stop at any point. Every workout in it can be ridden without an account.

Week 1: microbursts and 2×15 sweet spot. Short, sharp, and finished before you would normally have warmed up.

Week 2: five more minutes of microbursts, five more of sweet spot. Small steps, taken every week.
W3VO2 and threshold148
Week 3: the VO2 pyramid and a threshold session. The hardest week before the break.
W4Recovery week84
Week 4: recovery. Yes, in a six-week plan. Three weeks at this density has cost you more than the hours suggest.
W5Biggest week181
Week 5: 40 minutes of microbursts and 3×15 sweet spot. The peak of the plan.
W6Finish and test85
Week 6: one last microburst session, an easy spin, then the ramp test. Short protocol, honest number.
Every session is a real workout you can open and ride now. Starting the plan schedules all 18 from your chosen date, on the days you pick.
Start Time-Crunched 6-WeekRide this plan if
- You have three to four hours a week and no realistic prospect of more.
- You already have some cycling fitness and want to hold or improve it.
- Your sessions have to fit into weeknight windows of an hour or less.
What you get out of it
- Sustained power maintained or improved on very little volume.
- Microburst tolerance — the repeated hard efforts that decide group rides.
- A re-measured FTP at the end, on the short ramp protocol.
How the plan is built
This plan runs three rides a week for six weeks. Two carry hard work — microbursts and sweet spot or threshold intervals — and one is aerobic. The recovery week at week four is not optional; at this intensity density it is what keeps the last two weeks productive.
It will not build the endurance for a five-hour event. It will keep and grow your sustainable power through a busy stretch, which is usually the actual problem.
- Three rides a week, every one of them purposeful.
- Microbursts grow from 30 to 45 minutes across the plan.
- A full recovery week at week four, despite the plan being only six weeks long.
Time-Crunched 6-Week: common questions
Can you get faster on three hours a week of cycling?
Yes, up to a point. On low volume, intensity does the work that time normally would, so most of the sessions carry hard efforts. The ceiling is lower than on high volume, but the improvement in the first block is often substantial.
What are microbursts?
Very short efforts — typically 15 to 30 seconds — well above threshold, with equally short recoveries, repeated for several minutes. They accumulate a lot of time at high oxygen uptake in a session that fits inside 45 minutes.
Why does a six-week plan need a recovery week?
Because the intensity density is much higher than in a normal plan. Three hard-ish sessions a week for three weeks running produces real fatigue even when the total hours are small.
What to ride after this
Training works in blocks. These plans pick up where this one leaves off.
Sweet Spot Base
Eight weeks of sweet spot work at 88–94% of FTP, progressing 2×15 → 3×20 minutes, wrapped in enough Zone 2 to keep it sustainable.
