Indoor cycling for outdoor riders and racers
What indoor riding does well, what it can't do, and how to fit it around outdoor rides through the wet months before the Berkeley Omnium.
Rain on the window, wet roads and an early sunset don't have to mean a week off the bike. Some of the most fun riding in a Berkeley winter happens indoors: loud music, an instructor calling the efforts, and a room full of riders going through the same climbs and sprints together.
In Berkeley, CycleBar Berkeley on University Avenue is where a lot of that happens. It sponsored the 2026 Berkeley Omnium, and its classes are an easy way to keep riding with other people until the roads dry out.

The short answer
Indoor riding, in a studio class or on a home trainer, is a good way to keep riding consistently when it's wet or dark, and to do hard efforts without traffic or stops. It can't teach bike handling, group riding, cornering or descending, so keep riding outside when you can, especially in the weeks before a race. Count indoor sessions as part of your weekly training, not on top of it.
Rainy day? Ride inside with CycleBar Berkeley
A trainer alone in the garage is hard to love in January. A class is different: someone else plans the ride, the playlist carries you through the hard parts, and the riders around you keep you honest. The hour goes fast.
Count a class as training, and keep riding outside when it's dry. The rest of this guide covers how to make the two work together.
Three ways to ride indoors
| Option | What it's like | Good for |
|---|---|---|
| Studio class | An instructor-led group class on studio bikes, with music and set intervals | Riding with other people, motivation, a set time in your week |
| Smart trainer at home | Your own bike on a trainer, often with an app that sets the resistance | Structured workouts, exact targets, using your own bike and position |
| Basic trainer or rollers | Your own bike, with resistance you change by shifting | Easy spins and simple intervals; rollers also train balance |
None of these is the right one for everyone. A studio class is the easiest to start with and the most social. A trainer at home fits a busy schedule and a structured plan.
What indoor riding is good for
- Riding consistently. A few rides every week through the wet months does more for your April racing than a few long rides when the weather allows.
- Hard efforts with no interruptions. No stop signs, traffic or descents to break up an interval.
- Using limited time well. A 45-to-60-minute session fits around work and family.
- Pedaling skills. Steady cadence and smooth pedaling are easy to practice when you don't have to watch the road.
- Riding with other people when the roads are wet, in a class.
What it can't replace
Road racing is about more than fitness. The skills that keep you safe and in the race only come from riding outside.
- Bike handling: braking, cornering and riding a line on real roads.
- Group riding: holding a wheel, riding close to others and moving through a group.
- Descending, which matters on the Berkeley Hills Road Race's Three Bears loop.
- Cornering at speed, which is most of a criterium like the Berkeley Streets Criterium.
- Pacing real climbs, where the gradient changes and you can't set the resistance.
- Eating and drinking while riding, and your own bike position over hours.
Get outside on dry days, and plan the last weeks before a race to be mostly outside, on roads like the course.
How indoor sessions fit a training week
- Count it. An indoor session is training. A hard class counts as one of your hard days, not as an extra.
- Know which kind it is. If you ride a class all-out, it's a hard day. If you hold back, it can be a moderate one. Decide before you start.
- Don't stack hard days. Avoid a hard class the day after a hard group ride or race.
- Keep easy days easy. Recovery rides are what let the hard days work.
- If you have a coach or a plan, ask where a class fits. A studio class isn't the same as a structured, race-specific workout.
Training with purpose means deciding what each ride is for. The training stage of our path to racing covers how to build a week.
Sample rainy-season weeks
These are examples to adapt, not training plans. Adjust to your fitness, your schedule and how you recover.
| Rider | Indoors | Outdoors |
|---|---|---|
| Getting fit for group rides | One or two classes or trainer rides, one of them harder | One group ride or longer ride when it's dry |
| Building toward a first race | One structured interval session and one easy spin | A longer weekend ride, with a group when you can |
| Racing the Omnium | Interval sessions as your plan or coach sets them | Long rides and group rides outside, more of them as April gets closer |
Making indoor rides count
- You sweat more indoors without moving air. Use a fan at home, bring a towel and drink more than you might outside.
- Fuel longer or harder sessions the same way you would outside.
- Set up the bike to match your outdoor position as closely as you can: saddle height first. In a studio, ask the instructor to help.
- Check what pedals a studio uses before your first class, and bring your shoes if they fit.
- Short, focused sessions beat long, aimless ones.
How much to drink and eat depends on how long and how hard you ride.
Getting back outside
- Make the first ride back easy, and get used to the road again before you go hard.
- Check your bike after weeks off: tires, brakes and a clean, lubed chain.
- Rejoin group rides to bring your pack skills back before racing.
- Practice the things the race asks for: climbing and descending for the Berkeley Hills, cornering for the crit.

Questions
Indoor cycling for outdoor riders and racers: FAQ
Is indoor cycling good training for road racing?
Yes, for fitness and consistency. Indoor sessions are a good way to do focused efforts and keep riding through wet or dark months. They don't build bike handling, group riding, cornering or descending, so racers still need regular outdoor rides, especially before a race.
Can a spin class replace outdoor riding?
Not completely. A class builds fitness and helps you ride consistently, but outdoor skills only come from riding outside. Use classes alongside outdoor rides, and count a hard class as one of your hard days.
How often should I ride indoors in the winter?
As often as it helps you ride consistently, as part of your week rather than on top of it. Many riders mix one or two indoor sessions with an outdoor ride when it's dry. If you have a coach or plan, ask where indoor sessions fit.
Do I need a smart trainer or power meter to train indoors?
No. A studio class or a basic trainer works. A smart trainer or power meter makes structured workouts more precise, which matters more as your training gets more specific.
What should I bring to an indoor cycling class?
Water, a towel and cycling shoes if they fit the studio's pedals. Check the studio's pedal system before your first class, and ask the instructor to help set up the bike.
