In the world of cycling, we often hear about structured training, power zones, and targeted workouts. But today, I want to talk about a much-maligned concept in our sport: the so-called “junk miles.”
First, let’s clarify what we mean by “junk miles.” These aren’t short, slow rides to the café or around the neighborhood. We’re talking about longer road rides without a specific training focus – no intervals, no targeted heart rate zones, just riding your road bike at a comfortable pace.
Many cyclists, especially those who don’t race but still want to improve, often feel guilty about these less structured rides. They worry they’re wasting time or not maximizing their potential. But I’m here to tell you that these miles are far from junk. In fact, they can be incredibly valuable, especially for recreational riders.
Here’s why you shouldn’t dismiss your “junk miles”:
- Base Fitness: These steady, moderate-paced rides are excellent for developing your aerobic base. They improve your body’s ability to use fat as fuel and increase capillary density in your muscles.
- Active Recovery: If you do incorporate harder workouts, these easier rides can serve as active recovery, helping flush out your legs without adding more stress.
- Mental Refreshment: Constantly pushing yourself can lead to burnout. Rides without specific goals allow you to enjoy the simple pleasure of cycling, reducing stress and reinvigorating your love for the sport.
- Skill Development: Relaxed rides give you a chance to focus on skills like cornering, descending, or riding in a group without the pressure of maintaining a certain power output.
- Exploration: Without a rigid plan, you’re more likely to explore new routes, potentially discovering great new training grounds.
- Volume: For recreational riders, overall riding volume often matters more than intensity. These “junk miles” contribute to your total time on the bike, which has value in itself.
Now, this doesn’t mean every ride should be unstructured. If you have specific fitness goals and you’re trying to improve, you’ll want to include some targeted workouts. But for most recreational cyclists, having a good portion of your rides be less structured isn’t just okay – it can be beneficial.
My advice? Embrace these rides. Set a goal to explore a new route once a week, or challenge yourself to ride without looking at your computer. You might find that these “junk miles” become some of your most enjoyable and rewarding rides.
Remember, unless you’re training for serious competition, the best training plan is one that keeps you consistently riding and loving your time on the bike. If that includes a healthy dose of so-called “junk miles,” then pedal on with a clear conscience!
In the end, the only truly junk miles are the ones you don’t ride at all. So get out there, enjoy your bike, and don’t let anyone make you feel guilty about those leisurely, unfocused rides. They’re doing more good than you might think.
Another thing junk miles are good for: acclimatizing to riding in the heat and getting your hydration dialed in. I am prepping for a 6-day gravel bike packing trip, and have used a moderately paced weekly 40-70 mile ride with a couple of older riders to get used to the heat and as a pre-ride to a following day of riding without serial dehydration.
….or rebrand these rides as zone 2 and all is good!
It’s not junk miles, I’m training in Zone 2 as recommended by Huberman, Patrick and Attia!
Thanks, I’m definitely using that one in the future. Good idea. Sounds very scientific that way.
Exactly!
There is no such thing as junk miles. Full stop.
There is a lot of science these days behind Zone 2 training, which by the way, is used by many pros like Pogacar. See two instructive videos:

It’s the real deal!
I’m glad to see that I’ve been doing it right all these years.
Also I don’t race, never have and never will. No interest whatsoever.
