Indoor Cycling Training Plan for Beginners
For anyone whose riding keeps getting called off by rain, dark evenings or a full diary. Eight weeks of indoor cycling training: two short indoor sessions a week with a purpose, a weekend ride outside when you can get one, and an easy spin if you fancy it. You start with 20 minutes indoors and a 45-minute ride outside. By week eight you’re riding an hour indoors without watching the clock, and two hours outside that feel easy.

Who this plan is for
Train indoors, ride outdoors. The weather, the daylight and the week you actually have are the three things that stop most new riders, and an indoor bike gets round all three: twenty minutes before work in the dark, or in the evening while dinner cooks, with no kit to put on beyond a pair of shorts. The weekend ride outside is where you use the fitness, and where cycling stays fun.
It assumes you can pedal for 20 minutes without stopping, on any bike, and that you have, or can get to, something to ride indoors. You don’t need to be fit, and you don’t need to know anything about training: every session says how it should feel, in plain words. If you already ride an hour or two outside and want indoor sessions to keep you going over winter, start at week four.
If you’re new to exercise, have a health condition, or get pain on the bike that isn’t ordinary muscle soreness, see a doctor before you start. This is general guidance, not medical advice, and the app that personalises it isn’t a medical service.
What you need, and what you don’t
You don’t need a smart trainer (one that sets the resistance for you and connects to an app). This plan works on whatever you have, because it runs on how hard a session feels rather than on numbers from a screen.
A basic turbo trainer. Your own bike clamped into a stand with a resistance unit at the back wheel. You make it harder with your gears, exactly as you would on a hill. The cheapest way in, and your bike already fits you.
A spin bike or a gym exercise bike. Make it harder with the resistance knob or the level buttons. Set the saddle so your knee is only slightly bent at the bottom of each pedal stroke; most gym bikes are set far too low.
Nothing indoors at all. Ride the same sessions outside, shorter: the steady blocks on a flat loop, the short efforts up a hill (one minute up, roll back down easy). Twenty to forty-five minutes before dark is enough. You’ll miss the odd one to the weather, and that’s fine.
Whichever you use, three things make indoor riding bearable: a fan pointed at you (you’ll get much hotter than outside, and an overheated session feels twice as hard), a towel and a full bottle, and something to watch or listen to. Padded cycling shorts help more indoors than out, because you sit still for longer.
How each session should feel
Three efforts are all you need. Easy is a pace you could chat at in full sentences; most of your riding is this. Steady is short sentences: breathing deeper, still in control, a pace you could hold for an hour. Hard-ish is a few words at a time, an effort you could hold for five or ten minutes but no longer. Nothing in this plan is all-out. If you have a heart-rate monitor you can use it, but feel works just as well indoors, and better than you’d think.
What the eight weeks look like
Weeks one and two get you used to sitting on an indoor bike, everything easy. Weeks three and four add short steady blocks to one session. Week five is easier, because the fitness you build shows up once you’ve rested. Weeks six and seven add a session of short hard-ish efforts and lengthen the steady blocks. Week eight is the check: an hour indoors with two fifteen-minute steady blocks, then the longest ride outside.
The indoor sessions grow by about five minutes a week and the weekend ride by fifteen. If you can’t get outside at the weekend, ride it indoors but cap it at 75 minutes, or split it into two sessions on the same day. A long indoor ride is the fastest way to start hating your indoor bike.
| Weeks | Focus | Sessions grow to | How it should feel |
|---|---|---|---|
| 1–2 | Getting used to it: two easy indoor sessions and a ride outside | Indoors 20 → 30 min; outside 45 min → 1 h | Easy. Chatting pace, legs turning lightly. |
| 3–4 | Steady blocks: 3 × 5 min, then 3 × 8 min, in one session | Indoors 35 → 40 min; outside 1 h 15 → 1 h 30 | Mostly easy. The steady bits are short sentences. |
| 5 | Easier week | Indoors 30 min; outside 1 h | Fresh by the end of the week. |
| 6–7 | Build: short hard-ish efforts in one session, 2 × 10 min steady in the other | Indoors 45 → 50 min; outside 1 h 45 | Purposeful. Hard-ish is a few words at a time, never a sprint. |
| 8 | The check: 2 × 15 min steady indoors, and the longest ride outside | Indoors 1 h; outside 2 h | Compare it with week one. That’s the point. |
Tuesday: 20 minutes indoors. Five very easy to warm up, ten at chatting pace, five very easy to finish. Thursday: the same, 25 minutes. Saturday: 45 minutes outside on quiet roads, easy, or 30 minutes indoors if the weather says no. Four rest days. Week two adds five minutes to each indoor session and fifteen to Saturday.
A sample week
Week six, in the build. Every indoor session starts with ten minutes of easy pedalling and ends with five; the times below include them. If you only have two days, keep Tuesday and Saturday.
| Day | Session | How long | How it should feel |
|---|---|---|---|
| Monday | Rest | — | Off the bike. A walk is fine. |
| Tuesday | Indoors: 6 × 1 min hard-ish, 2 min easy between | 45 min | The efforts are a few words at a time; the two minutes between are properly easy. Breathing settles before the next one. |
| Wednesday | Rest, or strength off the bike | 0–20 min | Squats, lunges and a plank, if you fancy it. |
| Thursday | Indoors: 2 × 10 min steady, 5 min easy between | 45 min | Short sentences in the steady blocks. A slightly lighter gear than you think, legs turning quickly. |
| Friday | Rest | — | Check the tyres for the weekend. |
| Saturday | Ride outside | 1 h 45 | Easy throughout, with a stop if you want one. Eat something every 30 to 45 minutes from the first hour, and drink regularly. |
| Sunday | Easy spin indoors (optional) | 20–30 min | Very light. Legs turning, nothing more. Skip it if you’re tired. |
Rain, dark evenings, a full week. Your guide works round all three.
Tell Etapa how much you ride now, and it builds a guide around your week. Interval sessions (short harder stretches with easy riding between) can be sent to a smart trainer or indoor bike; on a spin bike or a basic turbo, every session carries a plain note on how it should feel. Miss one and the week is rebuilt rather than piled up.

How to adjust it when life happens
Missed a session? Let it go and carry on with the next one. Don’t squeeze two into one day. If you miss a whole week, repeat the last week you finished.
Sun’s out? Swap any indoor session for a ride outside of the same length and the same feel. The steady blocks work on a flat road, the short efforts up a hill. Indoors is the backup, not the rule.
Feeling wiped? Easy sessions that feel hard, worse sleep, dreading the next one. Bring week five forward and keep everything easy for a few days. Hot rooms make this worse: if your sessions keep feeling harder than they should, open a window and add a second fan before you blame your legs.
Ill? Rest until it’s gone, then come back with an easy 20 minutes. Sweating it out on an indoor bike doesn’t work.
Bored? Change something every ten minutes: stand up for thirty seconds, shift up a gear for a minute, put a different playlist on. It also gives your backside a break.
The basics
Drink more than you would outside: you’ll lose a lot more sweat in a warm room. Half a bottle on a 30-minute session and a full one over an hour is about right. You don’t need to eat on rides under an hour, but have something within an hour or so afterwards, especially after an evening session. If the saddle hurts indoors, stand for a few seconds every ten minutes, and check the saddle is level. More in our guides to beginner cycling gear and what to eat before, during and after a ride.
After the eight weeks
By week eight you can ride an hour indoors and two hours outside at a pace you could chat at. That’s the starting point for most first goals. The 8-week 50 km plan is the natural next step, and if your two-hour rides already feel comfortable, the metric century plan is within reach. Both work with indoor sessions in the week and a longer ride outside at the weekend. Not sure what to aim for? Find a cycling goal worth training for.
Is indoor cycling good training for riding outdoors?
Yes. Your legs, heart and lungs can’t tell the difference, and an indoor session is often better training minute for minute, because there are no junctions, traffic lights or downhills to coast on. What it can’t teach is handling: cornering, braking, riding in wind and traffic. That’s why this plan keeps a weekend ride outside whenever you can get one.
Do I need a smart trainer for indoor cycling training?
No. A smart trainer sets the resistance for you and talks to an app, which is handy but not necessary. Every session in this plan is described by how it should feel, so a basic turbo trainer (a stand that holds your own bike), a spin bike, a gym exercise bike or rollers all work. If you have nothing indoors, the same sessions can be ridden as shorter rides outside.
How long should an indoor cycling session be for a beginner?
Start with 20 to 30 minutes. An indoor session feels longer and harder than the same time outside, because you never stop pedalling and there’s no breeze to cool you. This plan grows the indoor sessions by about five minutes a week to an hour by week eight, which is as long as most people ever need to ride indoors.
How often should a beginner do indoor cycling?
Two or three times a week is plenty, with at least one rest day between the harder sessions. This plan uses two indoor sessions with a purpose, an optional easy spin and a weekend ride outside. More than that in the first couple of months tends to tire you out rather than make you fitter.
Does a spin class count as indoor cycling training?
It does. Most spin classes are hard from start to finish, so treat one as that week’s harder session and keep your other rides genuinely easy. If the class leaves you wiped out for two days, ride it a little easier: you set your own resistance, whatever the instructor says.
Training indoors works best with a reason to go outside
Pick a ride a few months away and the indoor sessions in your week start building towards it. When the weather turns, your guide moves with it.
