Trainer Season – Making Indoor Miles Count

I bought a Wahoo Kickr three winters ago after one too many “I’ll just ride through winter” declarations that ended with me on the couch by mid-January. Best cycling purchase I’ve ever made after the bike itself. I’ve logged more winter miles on that thing than I ever did outside in the cold, and my spring fitness hasn’t fallen off a cliff since.

Choosing Your Setup

Smart trainers like the Wahoo Kickr or Tacx Neo connect to apps and adjust resistance automatically during workouts. You load up a training plan and the trainer does the thinking — it ramps the resistance up for intervals and backs off for recovery. It’s like having a coach controlling your effort. These run $800-1,200 for a good one, which isn’t cheap, but they last years and you’ll use it more than you think.

Basic “dumb” trainers — the kind where you manually adjust resistance with a lever — cost $200-400 and work perfectly fine. I used a Kurt Kinetic for two years before upgrading. You miss the automatic resistance control and the power data, but the actual fitness benefit is nearly the same. If the price of a smart trainer is stopping you from riding indoors at all, get a basic trainer and start pedaling.

Making Indoor Rides Not Terrible

Let’s be honest: staring at a wall while pedaling is miserable. The apps are what make indoor training tolerable — and sometimes genuinely fun.

Zwift is the one everyone knows. Virtual world, your avatar rides along, you can join group rides and races. I was skeptical until I tried it and found myself actually sprinting for a virtual finish line at 10pm on a Wednesday. It works. The social aspect — riding with real people in real time — makes a huge difference.

TrainerRoad is for the data-driven crowd. No virtual world, just structured workouts with clear power targets. I use it during base-building blocks when I need discipline more than entertainment. It’s less fun than Zwift but arguably more effective for structured training.

My hack for long indoor rides: Netflix on a tablet propped up in front of me. A 90-minute endurance session paired with a couple episodes of whatever I’m watching goes by surprisingly fast. Podcasts work well too. Anything to keep your brain occupied while your legs do the work.

Effective Indoor Workouts

The biggest mistake people make is trying to replicate outdoor ride duration indoors. An hour of focused indoor training is worth 90 minutes of outdoor riding because there’s no coasting, no stoplights, no descents. Every pedal stroke counts. Embrace that efficiency — 45-60 minute sessions three or four times a week will maintain your fitness through winter.

Intervals are your best friend on the trainer. Sweet spot intervals (20-minute blocks at 88-93% of your threshold power), VO2max intervals (3-5 minute efforts at 105-120%), and tempo blocks all work brilliantly indoors because you can hit exact targets without wind or terrain messing things up.

You NEED a fan. Maybe two fans. Indoor riding generates ridiculous amounts of heat with no wind to cool you down. I have a box fan pointed at my chest and a smaller one aimed at my face. Without them I’m a puddle in 15 minutes. Sweat towel draped over the bars is mandatory too.

Don’t neglect recovery rides. Not every indoor session needs to be a suffer-fest. Easy 30-minute spins at conversation pace help your legs recover and keep the habit of getting on the trainer without dreading it.

The trainer is a tool, not a replacement for the real thing. Use it to build fitness through the dark months so that when spring arrives, you’re ready to ride instead of starting from scratch. That’s the whole point — and three winters in, I can tell you it works.
