Halfway through the café stop, a rider rubs their quads and blames the burn on lactic acid still sitting in their legs from Saturday.
Everyone nods, because we’ve all heard the same lines on club rides for years.
We’ve covered the beginner stuff in our earlier list of cycling myths.
Here are ten insider favorites that didn’t survive a closer look, plus what to do instead.
1. Lactic Acid Is What Makes Your Legs Sore the Next Day
We’ve all done the math in our heads. Burn on Saturday plus pain on Monday must mean the same stuff stuck around.
It didn’t. Lactate clears from your blood within about an hour after you stop pedaling, while that stair-climbing soreness shows up much later. A 2021 review of soreness research tossed the old lactic acid explanation for next-day soreness.
So lactate isn’t leftover waste hanging out in your legs. It’s fuel your body reuses.
Stop blaming lactate for pain two days later.
2. Narrow, Rock-Hard Tires Are Faster
Skinny used to mean speedy. If you weren’t rattling your fillings loose on 23s, you were clearly leaving watts on the table.
Lab testing didn’t agree. Wider tires from 23 to 32 mm rolled farther on both tarmac and cobbles, with the benefit flattening past 30 mm.
That doesn’t mean soft and squishy wins everything. It just means width isn’t the enemy we thought it was.
If your frame has room, try 28 to 30 mm tires.

3. Cramps Mean You’re Dehydrated or Low on Salt
Every group has handed out salt tabs at mile 70 like they were spare tubes. The story was simple. You cramped because you didn’t drink right.
Fatigue looks like the bigger culprit. In a large cycling cramp study, about 30% had cramped at some point, mostly in the quads and mostly late in a race.
Pace cautiously and train for late-race fatigue.
4. You Can’t Drink Too Much on a Ride
For years the advice was drink early and drink often. More always sounded safer.
It isn’t. Overdrinking above sweat and urine losses is now recognized as the main driver of serious exercise hyponatremia, which means low blood sodium from dilution. A cycling time-trial analysis found losing about 2% of body weight didn’t hurt self-paced performance in conditions around 79°F (26°C).
Drinking past thirst didn’t help either. Your bottle isn’t a homework assignment to finish.
Drink to a plan matched to your sweat, not to excess.
Our guide to how much to drink covers electrolytes and how to set that plan.
5. Coffee Before a Ride Will Dehydrate You
Plenty of us have loved the pre-ride espresso while quietly worrying we’d pay for it by noon. Caffeine feels too good to be harmless.
It’s pretty harmless for fluids. In habitual coffee drinkers, four small cups a day hydrated about the same as water, and that dose was about 27 US fl oz (800 mL).
So you don’t need to choose between your ritual and your hydration. Just don’t turn it into a late-night double-shot habit that wrecks sleep.
Keep the pre-ride coffee if you like it.
6. Stretching Before a Ride Prevents Injury
We’ve all seen the parking lot routine. Touch the toes, yank the heel to the butt, then ride injury free.
It doesn’t work that way. In a big trial of army recruits doing static stretches at every warm-up, the stretch group suffered 158 injuries versus 175 in controls, a difference small enough to be chance.
That isn’t quite club riders on carbon bikes, but it’s a strong nudge.
Warm up with easy spinning, not parking-lot stretching.
7. Every Ride Should Hurt
No pain, no gain followed a lot of us from school sports to the group ride. If your eyes weren’t watering, you must have been loafing.
The fast folks do the opposite. Top endurance athletes perform about 80% of sessions at low intensity, with only about 20% hard.
Think of it like conversation at the café stop. Most of it’s easy chat, with just the odd spicy story. That mix lets the hard days actually be hard.
Ride mostly easy so your hard days can be truly hard.

8. Eat Protein Within 30 Minutes or You’ll Feel Wrecked Tomorrow
We’ve all heard the panic at the table. Miss the shake window and you’ll be sore for days.
You won’t be any sorer for missing it. In one trial of trained cyclists, protein drinks after hard intervals did no better for soreness than a carb-only drink with the same calories. A 2014 review of 27 studies of healthy adults under 50 found no solid evidence that protein after one session cuts soreness or speeds muscle recovery.
What matters is the pattern across days, not a stopwatch by the bike rack. The one exception is carbs if you’re riding hard again the same day. In my book, what you eat before and during the ride matters more than racing the clock afterward.
Eat a proper meal with 25 to 30 g of protein within the next few hours.

9. Cycling Is All the Exercise Your Bones Need
Cycling feels so wholesome it must build everything. Lungs, heart, legs, bones, all sorted by Saturday.
Bones didn’t get the memo. A review of 31 studies found regular road cycling gives no significant bone-building benefit.
That’s awkward news for a sport we love, but it’s fixable off the bike.
Lift heavy and add impact twice a week.

Then read whether to lift weights for the two-session rule.
10. The Twist: Shaved Legs Are Just Vanity
We always said it was tradition, or road rash care, or looking pro.
Then wind tunnel folks tested six riders before and after shaving. Savings ran from 50 to 82 seconds over 25 miles (40 km), roughly a minute on average at time-trial speed. It was a manufacturer test with six riders that never went through peer review, so take it as a fun hint rather than lab law.
At café speed it’s style. At race speed it’s free time you didn’t have to suffer for.
Shaved legs are free speed on a fast day.
What to Change on Your Next Ride
Pick three easy wins this week. Drink to a plan instead of forcing extra bottles.
Keep most rides easy so one session can be properly hard. Add strength and impact work for your bones, with roughly 25 to 30 g of protein in the meal after.
