A 30-DAY SPRINT POWER BLOCK: HOW I STRUCTURE THE FIRST MONTH OF TRAINING

By Anthony Walsh

People ask me what a structured training month actually looks like more than almost anything else. So I built one out and walked through it session by session on Boost Your Cycling Fitness in 30 Days on the Roadman Cycling Podcast. This is that block written down — what each session is for, how the four weeks build, and the one mistake that turns a good plan into a plateau.

A quick caveat before we start. This is a snapshot. It's the first block of a four-block plan I'd build for a client, and it works because the stimulus keeps changing across those blocks. If you take this single month and run it on repeat, you will stagnate. More on why at the end.

Key Takeaways

• One primary adaptation per session — mixing sprint, tempo and threshold in the same ride blunts all three • Reverse periodisation: sprint power first (this block), then VO2, then threshold, then event-specific work • Set zones from a 20-minute FTP test paced as even quarters, building to the hardest effort in the final five minutes • Two sprint sessions a week drive the adaptation; a cadence session and weekend endurance support them • Sprint efforts demand full commitment — set your posture, hold the bars hard, explode through the pedals • Weekend endurance grows gradually across the block: roughly 3+3 hours, then 3+4, then 4+4 • Test sprint power on day one, retest at the end of week four to confirm the adaptation landed • Run this block once — it's the first of four, not a plan to repeat

Set Your Zones First: The 20-Minute Test

Before any of the sessions matter, you need accurate zones. There are several ways to find them, but the one that repeats most reliably for me is a 20-minute FTP test — or 25 minutes if you're working off heart rate.

The thing that makes or breaks this test is pacing. You're trying to cover the most distance you can across the full 20 minutes, not blow yourself apart in the first kilometre and hang on. I've paced these badly before, and it's a lonely place to be. I subdivide the effort into four five-minute quarters and try to negative split: the first quarter sets the rhythm, each one after builds slightly, and the final five minutes is everything you have left. My old coach Mike Barry — former Team Sky and T-Mobile rider — used to tell me that in the last minute you need to go until you see Jesus. That's the intensity I want in that closing quarter.

Take the average power across the full 20 minutes and use that to set your zones. Our free FTP zone calculator will turn that number into individualised zones for you. Don't train off generic percentages of a guessed FTP — that's how riders end up stuck in the grey zone, too hard to build aerobic base and too easy to drive real adaptation.

One Adaptation Per Session, And Why Sprint Power Goes First

This block runs on reverse periodisation: sprint power first, then VO2 power in block two, threshold in block three, and event-specific demands in block four. I'll be straight with you about the periodisation debate — I had a long conversation with Professor Stephen Seiler about whether reverse, traditional or randomised intensity is best, and the honest upshot is that over the long run it doesn't matter much. They all work. I use reverse periodisation here because starting with speed is motivating and it gives you a clear, testable goal in month one.

What does matter, and matters a lot, is one primary adaptation per session. The most common mistake I see in self-built plans is a session with no overriding focus — a bit of threshold, a bit of tempo, a couple of sprints, all jammed into one ride. Ask one question of every session: is this ride about going fast, or about building endurance? In this block, two sessions a week are dedicated to sprint power and nothing else.

And sprints mean sprints. A sprint session is about full commitment, not going through the motions. I give clients a visualisation: picture a stick of dynamite with the fuse ticking down through the ten seconds before the effort. You're setting your posture, holding the bars hard, building tension — and when the fuse hits zero, you explode through the pedals like you're trying to rip the cranks off. Apologetic sprints produce no adaptation.

The Four Weeks, Session By Session

The weekly shape stays consistent and the volume builds gently. Monday is a rest day. Friday is a mobility day — effectively another rest day with a 20-to-30-minute easy mobility routine. The two sprint sessions sit on Tuesday and Thursday, with a cadence session on Wednesday and endurance at the weekend.

Week one opens with a sprint test on Tuesday so you have a baseline to retest against. It's a Zone 1 to Zone 2 ride with five 10-second maximal sprints folded in, warmed up properly, with generous recovery between efforts — anything over 60 seconds of rest and you've recovered most of what you'll get, so two to five minutes is fine. Wednesday is a high-cadence session in Zone 2, working through a ladder from 80 up to 110 RPM and back — gentle, not taxing, the kind of thing you can do with something on in the background. Thursday is 5×30-second maximal sprints, three out of the saddle and two seated, after a high-cadence Zone 4 spin-up warm-up, with four and a half minutes between efforts. The weekend is two Zone 2 endurance rides of about three hours each.

Weeks two and three keep the same skeleton and grow the weekend volume — roughly 3+4 hours, then 4+4 — while the sprint work shifts to keep the stimulus fresh. You'll see neuromuscular sets like 4×15-second flat-road sprints where you let cadence run to its absolute maximum without shifting down, and mixed turbo sessions pairing spin-ups with short maximal efforts inside a Zone 2 ride. The cadence session stays in the week; for a real client I'd vary it weekly for variety, but the job it does — smooth, high-RPM Zone 2 — stays the same.

Week four is the close of the block. It's a touch easier so the adaptation can settle, and it finishes with a retest of sprint power. That bookend — test on day one, retest at the end — is what makes the block work for busy riders. You're not hoping you got faster. You're measuring it.

What This Means for Your Training

If you take one thing from this, make it the one-adaptation rule. You don't need a coach to apply it tomorrow: look at your next hard session and ask what it's actually for. If the answer is "a bit of everything," rebuild it around a single target. That alone fixes a lot of stalled training.

Be honest about the time requirement. This block is built around roughly 10 hours a week. If you've got less, don't try to compress it — keep the two sprint sessions intact and scale the weekend endurance down proportionally rather than cramming intensity into every spare hour.

Retest, every block. The sprint test on day one and the retest at the end aren't optional decoration — they're the only way to know whether the month did its job. Carry that habit into the next phases: test VO2 at the top and tail of block two, threshold at the top and tail of block three.

And the big one: run this block once. It's block one of four. Block two targets VO2 power, block three threshold, block four the specific demands of your event. The reason you don't repeat month one on a loop is progressive overload — your body adapts to a fixed stimulus and then stops responding. Use this as a template for how a structured month is built, then build the next one differently.

If you've been training with structure and the numbers still aren't moving, the limiter may not be the plan at all — it could be recovery, intensity distribution, or how the two are interacting.

FAQ

FREQUENTLY ASKED QUESTIONS

How much riding time does this 30-day plan need?
Around 10 hours a week. The block is built for a fairly serious rider who can hold two sprint sessions, a cadence session and weekend endurance across seven days. If you have less time than that, the structure still teaches you something, but the volume won't land the way it's designed to. Scale the weekend rides down proportionally rather than cutting the two sprint sessions.
Can I run it off heart rate instead of a power meter?
Yes, with one change. Use a 25-minute test instead of 20 minutes to set your zones, because heart rate lags effort. The sprint sessions become more feel-based — you're chasing maximal effort, not a power number — so perceived exertion carries more of the load. A power meter makes the sprints easier to verify, but the block works on heart rate.
Why only one adaptation per session?
Because the body responds to a clear signal. If you stack a bit of threshold, a bit of tempo and a couple of sprints into one ride, you blunt the adaptation to all of them. Every session in this block has a single question behind it — are we building speed or building endurance? Sprint days are sprint days. Endurance days stay easy.
How much will my sprint power go up?
That depends entirely on your training history and how trainable your neuromuscular system is right now. The honest answer is that the retest at the end of the block tells you, not a number I can promise in advance. Newer riders tend to see the biggest jumps; experienced riders see smaller but real gains. The point of the retest is to measure what actually happened rather than hope.
Can I just repeat this block to keep improving?
No, and that's the most important caveat. This is block one of four. If you rinse and repeat the same month, your body adapts to the stimulus and you stagnate. After the sprint block you move to VO2, then threshold, then event-specific work — each phase changes the stimulus so you keep responding. Treat this as a snapshot of one month, not a permanent plan.
