STRUCTURED VS UNSTRUCTURED TRAINING: WHEN THE PLAN SHOULD BEND

By anthony-walsh

WHO THIS IS FOR

IS THIS YOU?

  • Riders who bought a training plan, followed it for six weeks, then abandoned it out of guilt or boredom
  • Cyclists who feel guilty every time they skip an interval session to ride with mates
  • Self-coached athletes trapped in the grey zone because every ride defaults to medium-hard without a plan
  • Anyone whose relationship with cycling has shifted from enjoyment to obligation because of rigid structure

THE ROADMAN VIEW

The Roadman View

  • I have watched riders quit cycling entirely because their training plan sucked the joy out of it. That is a coaching failure, not a discipline failure. The plan is supposed to serve you.
  • The cafe ride is not junk miles. The group spin is not wasted time. If those rides keep you in the sport for twenty more years, they are the most productive sessions on your calendar.
  • Eighty per cent structure, twenty per cent spontaneity. That is roughly where the long-term riders I have spoken to on the podcast land. The ratio shifts with the season, but the principle holds.

You bought a training plan. Maybe you paid for it, maybe you found one in a book, maybe a mate who races sent you a spreadsheet with coloured cells and abbreviations you had to Google. You followed it for six weeks. The legs were responding. The numbers were moving. And then on a Thursday evening the sun came out, someone texted, and you went for a two-hour café spin instead of your scheduled 4x8 sweet spot intervals.

You felt guilty about it. You shouldn't have.

Here's the thing nobody tells you about structured training: the structure is supposed to serve you, not the other way around. The plan is a tool. A good one — possibly the most effective tool an amateur cyclist has outside of consistency itself. But when the tool starts dictating every hour you spend on a bike, when it removes the spontaneity and social connection and sheer bloody enjoyment that put you on a bike in the first place, something has gone wrong. Not with you. With the plan.

I've spoken to over 1,400 guests on the podcast — coaches, physiologists, pro riders, and a lot of ordinary riders who are still getting faster at 45, 50, 55. The pattern is remarkably consistent. The riders who sustain long-term progression are not the most disciplined. They're the ones who found a balance between planned training and the rides that keep cycling fun. They built structure that bends without breaking.

This is about how to find that balance.

What Structure Actually Does for You

Let me be really clear about this: I am not arguing against training plans. If you have a specific goal — an event, a time, an FTP target, a sportive you want to finish without cramping at 80 kilometres — a structured training plan will get you there faster than riding by feel alone. The research is unambiguous. The coaching consensus is unambiguous. Structure works.

Here's what it does.

First, it separates easy from hard. Without a plan, most self-coached riders default to medium-hard on every ride. Not easy enough to build genuine aerobic base, not hard enough to produce threshold or VO2max adaptation. Stephen Seiler's work on polarised training showed this clearly — the grey zone is where training goes to die. A plan prevents that drift by telling you when to go easy (most of the time) and when to go properly hard (less often than you think).

Second, it provides progressive overload. Your body adapts to repeated stress, then stops responding. A good plan increases the stimulus gradually — longer intervals, more volume, higher intensity — across a training block, then backs off for recovery before building again. Without that sequence, you end up doing the same Wednesday night chain-gang effort for three years and wondering why your FTP hasn't moved.

Third, it creates accountability. When Thursday says "3x12 at threshold" in your calendar, you do it. When Thursday says nothing, you do whatever you feel like, which is usually a ride that sits in nobody's training zone and serves nobody's purpose. The plan gives each ride a reason to exist.

All of that is valuable. None of it is in dispute.

The question is what happens when the plan becomes the point.

When Structure Kills the Thing It's Supposed to Serve

I talk to a specific kind of rider more and more often. Late thirties, forties, fifties. Came to cycling because they loved it — the freedom, the headspace, the social element, the feeling of a long ride on a summer morning when the roads are empty. Then they got serious. Bought a power meter, downloaded a plan, started tracking CTL and TSB and all the rest of it. And within six months, something shifted.

Cycling stopped being a thing they chose to do and became a thing they had to do. Every ride had a prescription. Miss one and the guilt would sit on them like a wet jersey. The group ride got dropped because it didn't fit the plan. The café spin got dropped because it wasn't in the right zone. The route they'd been meaning to explore got dropped because it wasn't the right duration.

What's left is not cycling. It's compliance.

And here is where the data gets really interesting. Joe Friel — who literally wrote the book on structured training — has said repeatedly that adherence is the biggest predictor of results. Not the quality of the intervals. Not the precision of the zones. Whether the rider actually does the work, week after week, month after month. A plan that produces three weeks of perfect compliance followed by two weeks of guilt and zero riding is a worse plan than a loose framework followed consistently for six months. Full stop.

The riders who quit structured training are rarely unfit. They're bored. Or they're resentful. Or they've lost the thing that made cycling feel like freedom rather than obligation. That's not a discipline failure on their part. That's a design failure in the plan.

The 80/20 Rule — Applied to Structure Itself

You've probably heard about the 80/20 intensity distribution — 80 per cent of training at low intensity, 20 per cent hard. Seiler's research, backed by decades of data from elite endurance athletes. It works. But I want to borrow that framework and apply it to something different: the ratio of structured to unstructured rides.

Aim for roughly 80 per cent of your weekly rides to have a purpose. That purpose doesn't need to be complicated. "Easy Zone 2 endurance for 90 minutes" is a purpose. "Two sets of 8-minute threshold intervals" is a purpose. "Recovery spin, legs moving, nothing more" is a purpose. The point is that you get on the bike knowing what the session is for and roughly how it should feel.

The other 20 per cent? Completely unplanned.

A café spin with mates. A new route you've been eyeing on Komoot. A ride where you leave the head unit at home and ride by feel. A group ride where the pace is dictated by whoever showed up, not by a power target. A two-hour meander through lanes you've never seen because you turned left instead of right and kept going.

For a rider doing five rides a week, that's four with purpose and one without. For a rider doing six, it's five and one. The numbers aren't sacred. What matters is that the unstructured ride is not an accident, not a failure, not a deviation from the plan. It's part of the plan. Built in. Protected. Non-negotiable in the same way your threshold session is non-negotiable.

Because here is the uncomfortable truth: most amateur riders will stay in the sport for 20, 30, 40 years. And the thing that keeps people riding for decades is not a 5-watt FTP increase in March. It's the rides that remind them why they started.

Periodise Your Fun

Here's where it gets really interesting. You can — and should — adjust the ratio of structured to unstructured riding across the season, the same way you adjust volume and intensity.

Off-season and early base phase are where unstructured riding should dominate. This is the time to ride gravel, try mountain biking, explore new routes, join the social group ride every weekend, and generally fall back in love with the bike. The physiological demands of base training — lots of time at low intensity, building aerobic capacity — are perfectly compatible with unstructured riding. You don't need a power target for a three-hour easy spin. You need a route, a thermos, and someone to talk to.

As you move into build phase — typically 8 to 12 weeks before your target event — tighten the structure. This is when the intervals matter, when the recovery rides need to be properly easy, when the training block needs to progress. Your weekly structured-to-unstructured ratio might shift from 70/30 to 90/10. The group ride might need to become a specific training ride. The café spin might move to your rest day.

Race week and peak phase are fully structured. Short, sharp, intentional. Every session has a reason. This is not the time for spontaneity. But because you spent the off-season and base phase riding freely, you arrive at this block with something most rigid-plan followers have burned through months ago: genuine enthusiasm for training.

And after the target event? Back to unstructured. Recovery weeks, transition phases, the tail end of the season — ride for fun. Ride for coffee. Ride because the weather is absurd and you can't believe you get to do this.

The technical term for this is periodisation, and coaches like Friel have written entire books about it. But the principle is simple. Match structure to the season. Front-load fun. Tighten discipline when it counts. Release it when it doesn't.

The Group Ride Is Not Junk Miles

I need to say this plainly because I hear the opposite too often: the group ride is not a waste of your training time.

Yes, it's unpredictable. Yes, the intensity is variable. Yes, you'll probably ride harder than your plan says on Tuesday and easier than your plan says on Thursday. Yes, if you're four weeks out from your A-race and every session needs to be dialled in, the group ride might need to give way.

But for the other 40 weeks of the year? The group ride is doing more for you than almost any solo session in your plan.

It teaches bike handling in a bunch — a skill you cannot practise alone and that matters enormously in any event with other riders. It teaches pacing, because when someone attacks on a climb you learn very quickly whether you can follow and what it costs. It provides intensity variation that mimics race dynamics — surges, recoveries, sustained efforts on the front — without you having to programme any of it.

And it does something no training plan will ever do: it keeps you connected to other people who ride.

The social element of cycling is not a soft, optional extra. It is one of the strongest predictors of whether someone stays in the sport long-term. The research on exercise adherence is clear. People who ride with others ride more consistently, for more years, with fewer extended breaks. A training plan that eliminates group rides is a plan most people will eventually abandon.

So build the group ride in. If you need to treat it as "endurance with surges," fine. If you need to sit on the back for the steady bits and only push on the hills, fine. But don't drop it because a spreadsheet says you should be doing 3x15 threshold instead.

Unstructured Does Not Mean Easy

There's a misconception that unstructured riding is always easy riding. It isn't. Some of the hardest efforts most amateur cyclists produce happen completely spontaneously.

The town sign sprint. A rider comes past you on a climb and something in your legs says "not today." A headwind on an open road that you decide to fight at 42 kilometres per hour because the stubbornness kicked in. A group ride that turns into an unspoken race for the last 20 kilometres.

None of these efforts are in a plan. None of them target a specific power zone. None of them appear in your training log as a structured interval. And yet they produce genuine physiological stimulus — high heart rates, muscle fibre recruitment, lactate clearance demands — that your body will adapt to.

The difference between a structured interval and a spontaneous hard effort is not the intensity. It's the intent. Structured training says "today you will produce this specific stimulus for this specific duration at this specific intensity because we are targeting this specific adaptation." Unstructured intensity says "that was hard, I went deep, and I feel brilliant for having done it."

Both count. The structured approach is more efficient for targeting specific weaknesses. The unstructured approach is more efficient at keeping you honest about why you ride.

Dan Lorang, who coaches some of the best triathletes in the world, has talked about the value of athletes occasionally racing themselves in training — not because it's physiologically optimal, but because it reminds them they're competitors, not just data-entry clerks for a training platform. That competitive fire is hard to programme and easy to extinguish.

The Guilt Trap — And How to Escape It

Let me break this down because it's the part that does the most damage.

You have a plan. Today says "90 minutes Zone 2." Instead, you rode the group ride, went hard for 20 minutes on the hills, soft-pedalled for 30 minutes chatting at the café, and came home two hours later with a file that looks nothing like what was prescribed. Now you feel guilty. Tomorrow you try to make up for it by doing yesterday's session plus today's. The day after, you're tired, so you skip. Two days later, you've mentally abandoned the plan entirely and you're back to riding whatever.

Sound familiar?

The guilt is the problem, not the deviation. A single unstructured ride in a week of four structured sessions does not derail your training. It doesn't even dent it. What derails training is the emotional spiral that follows — the sense of failure, the compensatory overtraining, the eventual abandonment. That cycle costs more fitness than every café spin in history combined.

The fix is structural. Build the unstructured ride into the plan. Write "flexible ride" or "social ride" or "rider's choice" into your calendar on Thursday or Saturday. When you take it, you haven't deviated. You've completed the session as planned. No guilt. No compensation. No spiral.

It sounds almost stupidly simple. It is. It also works.

A Practical Weekly Template

Let me give you something concrete. A five-day riding week for a rider in mid-season build phase, training roughly 8 to 10 hours a week. Adjust the durations to fit your life, but hold the proportions.

Monday — Rest day. Off the bike entirely.

Tuesday — Structured intervals. This is your hard day. Threshold, VO2max, whatever your plan prescribes. 60 to 90 minutes with specific targets. Head unit on, data recording, full focus.

Wednesday — Easy endurance. Zone 2. 60 to 90 minutes. Keep it boring. Keep it easy. This session builds the aerobic base that makes everything else possible.

Thursday — Structured tempo or sweet spot. A moderate-intensity session with a specific purpose. 75 to 90 minutes. Not as hard as Tuesday, not as easy as Wednesday.

Friday — Rest day or very easy spin.

Saturday — The unstructured ride. Group ride, café spin, exploration, whatever calls to you. No power target. No duration target. Ride until you want to stop, ride wherever you want to go, ride with whoever shows up. Enjoy it.

Sunday — Long endurance ride. The big aerobic session of the week. 2 to 3 hours, Zone 2, steady effort. Pack food. Pick a route you like. This is the session that builds durability.

Four structured sessions. One unstructured. Two rest days. The ratio is 80/20. The hard days are hard, the easy days are easy, and Saturday exists purely to remind you that cycling is something you love, not something you endure.

During base phase, you might make Wednesday and Thursday less prescriptive too — more riding, less structure, more feel. During race week, Saturday becomes a targeted session. The template flexes with the season.

The Bigger Picture

Here's what most people do: they find a 12-week training plan, follow it rigidly for as long as willpower allows, then fall off and ride aimlessly until guilt drives them to find another plan. Rinse and repeat.

Here's what actually works: a year-round approach where the ratio of structure to freedom shifts with the season, where unstructured rides are protected rather than punished, where the group ride and the café spin and the random Tuesday evening ride because the sunset was too good to miss are all recognised as part of what keeps a person on a bike for 30 years.

The fastest masters riders I've spoken to on this podcast all have one thing in common. They train with purpose. But they also ride with joy. They don't sacrifice one for the other. They recognise that the structured interval on Tuesday and the unplanned hilltop sprint on Saturday are both doing something important — one for their legs, one for their head.

And both of those things need to be strong if you want to keep getting faster.

The best training plan is not the one with the best intervals or the cleverest periodisation or the most precise power targets. The best training plan is the one you actually follow. Week after week, month after month, year after year. And the plans people follow — actually follow, not just intend to follow — are the ones that leave room for the rides that made them fall in love with cycling in the first place.

Protect those rides. They're not a deviation from the plan. They are the plan.

FAQ

FREQUENTLY ASKED QUESTIONS

Should I follow a structured training plan?
If you have a specific performance goal — a target event, an FTP number, a climb time — a structured plan will get you there more efficiently than riding by feel alone. If you ride purely for enjoyment and health, structure is optional. Most riders benefit from a middle ground: a loose weekly framework with some flexibility built in.
How many unstructured rides per week is okay?
One to two unstructured rides per week is a sensible allowance for most amateur cyclists training five to six days a week. During base phase, you can increase that to two or three. During a build block leading into an event, tighten it to one. The key is that your hard sessions and your recovery sessions both have purpose — the unstructured rides fill the space between.
Will I lose fitness riding without a plan?
Not if you maintain consistency and include some intensity. Riders lose fitness from inactivity, not from unstructured activity. A rider doing five rides a week without a plan will be fitter than a rider doing three structured rides and skipping the other two out of plan fatigue. Consistency is the biggest predictor of fitness.
Is a group ride a waste of training time?
No. Group rides build bike handling, race awareness, and social bonds that sustain long-term participation. They also provide variable-intensity efforts that mimic race dynamics. The only issue is when every ride becomes a group ride and the easy sessions never happen. One or two group rides per week, balanced with easy and structured sessions, is productive.
How do I know if I need more structure?
If your fitness has stalled despite consistent riding, if every ride feels the same intensity, or if you cannot identify what each session is supposed to achieve, you need more structure. The clearest sign is the grey zone trap — riding too hard on easy days and too easy on hard days because there is no plan to anchor effort levels.

DOES AERO MATTER FOR AMATEURS? WHAT THE SCIENCE ACTUALLY SAYS | ROADMAN CYCLING PODCAST

Aero gets sold as free speed for pros, time triallists and triathletes — but does it matter for the everyday rider doing club runs and sportives? This solo episode cuts through the marketing. Your body, not your bike, makes most of the drag, which means the biggest gains are the cheapest ones: how you sit, how you hold the bars, and whether your kit actually fits. Here's when aero is real free speed, when it's expensive nonsense, and the $0 changes worth making first.
