Finding Your Perfect Road Bike – A Buying Guide

About Cycling and Calories

Cycling and calories has gotten complicated with all the fitness tracker noise flying around. As someone who has been riding for years and tried every gadget under the sun, I learned everything there is to know about how many calories you actually burn on a bike. Today, I will share it all with you.

My friend Matt asked me how many calories he burns on our rides. Gave him some vague non-answer because honestly who actually knows. But he kept asking so I looked into it properly.

The short version: it depends on way too many variables to give a real number. But here’s what I’ve pieced together from reading studies and my own experience on the road.

Weight Makes a Big Difference

When I was heavier — about 185 after a rough winter of too many IPAs and not enough saddle time — I was burning way more than my buddy who weighs 125. Same ride, same pace, completely different aftermath. I’d be destroyed and he’d look fresh enough to go again.

Rough estimates say the lighter guy burns maybe 240 calories per hour at moderate pace. The heavier guy? More like 355. That’s a significant gap for identical effort, which is why those generic “cycling burns X calories” articles are basically useless.

Pace Obviously Matters

Going slow and chatty burns 200-300 per hour. Not nothing, honestly. Pushing to 13-14 mph bumps it to 300-600 depending on conditions and your weight. Really hammering at 16 plus mph can hit 600-900 theoretically but almost nobody sustains that for a full hour.

I can do high intensity for maybe twenty minutes before I’m completely toast. The calorie calculators assume sustained effort that’s genuinely hard to actually maintain unless you’re racing.

What My Garmin Tells Me

Probably should have led with this section, honestly. I check the calorie count after rides but take it with massive skepticism. These devices are making educated guesses based on formulas and heart rate data. Good for comparing one ride to another on a relative basis. The absolute number? Pretty questionable.

My Edge 1040 says I burned 1,200 calories on a recent 2-hour ride. My friend’s Wahoo said he burned 900 on the same ride at the same pace. One of us is wrong. Probably both of us are wrong.

Weight Loss Reality

Can cycling help you lose weight? Yeah, definitely. Will it if you celebrate every ride with beer and nachos? Probably not. Ask me how I know — I gained five pounds during my biggest riding month ever because I “earned” those post-ride meals.

That’s what makes cycling endearing to us fitness-minded riders — the indirect benefits are real even when the scale doesn’t cooperate. I sleep better and crave better food on days I ride. Not some kind of iron discipline thing — just genuinely different appetite patterns.

Bottom Line

Ride because you enjoy it. The fitness stuff happens as a side effect. Obsessing over exact calorie numbers misses the whole point of being out on a bike. Get outside, move your legs, enjoy the scenery. The rest handles itself over time.
