Fit, Not Invincible: Health Problems Senior Cyclists Must Watch For

Last updated: February 6, 2026 – Updated with real-world tips from a 70-year-old long-distance cyclist.

Quick Take: Cycling keeps me strong, lean, and sane at 70—but it doesn’t make me bulletproof. Senior cyclists still face heart issues, inflamed knees, joint pain, heat problems, and skin damage. The key is catching problems early, listening when your body whispers, and using smart gear to protect your future rides.

As cyclists, we like to think we’re “the healthy ones.” We ride more than most people walk. We sweat, we climb, we push our limits. I’ve done that for decades—and at 70, I still ride long distances regularly.

But here’s the blunt truth: being fit does not make you invincible. It helps, a lot. It stacks the odds in your favor. But cyclists—especially older cyclists—are not magically protected from health problems.

This isn’t meant to scare you away from the bike. It’s meant to keep you on it longer. The more you understand the risks, the more you can do to ride smarter, safer, and stronger for many years.


1. Heart Issues Can Still Happen (Even If You Ride a Lot)

Cycling is one of the best things you can do for your heart. My own numbers look better now than they did in my 40s. But that doesn’t mean cyclists never have heart problems—especially as we get older.

Some riders, even those who put in regular miles, still experience:

  • Arrhythmias (irregular heartbeat)
  • Chest pain, tightness, or pressure
  • Shortness of breath that feels “wrong” for the effort
  • Unusual fatigue that doesn’t match your normal ride

If something feels off—listen to it. Dizziness, strange heart flutters, chest discomfort, or “I just don’t feel right” on a ride are all reasons to stop and get checked. Pride isn’t worth a heart attack.

If you’re a senior cyclist and haven’t had a basic checkup in a while, schedule one. Your future miles are worth that phone call.

2. Overuse Injuries & Inflamed Knees: The Price of Repetition

Cycling is low impact—but it is highly repetitive. That repetition is what sneaks up on us.

Over time, many cyclists (me included) deal with:

  • Inflamed knees from poor fit, too much climbing, or grinding big gears
  • Tendinitis around the knees or Achilles
  • Iliotibial (IT) band irritation on the outside of the leg
  • Hip tightness from staying in the same position mile after mile

Here’s where a lot of us get into trouble: we assume knee pain is “just part of cycling.” It’s not. Pain is feedback—and ignoring it can turn an irritated joint into a season-ending injury.

Things that have helped my knees over the years:

  • Backing off the gear and spinning at a higher cadence instead of grinding
  • Lowering ride intensity or volume for a few days when something first starts to hurt
  • Getting a proper bike fit instead of guessing at saddle height and cleat position
  • Using high-quality bib shorts and a supportive saddle to keep my position stable

3. Sun, Skin, and the “Price of the Saddle”

Cycling comes with two big skin threats: the sun above you and the saddle under you.

Spending hours in the sun without protection increases your risk of skin cancer. It also ages your skin faster than any birthday ever will. On top of that, long miles can bring:

  • Saddle sores
  • Chafing in all the lovely places your shorts rub
  • Rashes from sweat, heat, and friction

Some simple upgrades make a huge difference:

  • High-SPF sunscreen on every exposed area (yes, even cloudy days)
  • UV-protective arm sleeves and leg sleeves
  • Well-fitting padded shorts or bibs with good chamois
  • Anti-chafing cream on long rides or hot days

Cycling shouldn’t leave you raw, burned, and limping into the shower. A little preparation goes a long way.


4. Joint Strain: When “Low Impact” Still Hurts

Compared to running, cycling is much easier on the joints. But if your fit is off or you ride long hours with poor posture, you can still aggravate:

  • Knees (saddle too low or too high, cleat issues)
  • Hips (overreaching or rocking on the saddle)
  • Lower back (too aggressive or cramped position)
  • Wrists and hands (too much weight on the bars)

If you’re consistently sore in the same places after every ride, that’s a sign—not a badge of honor. A professional bike fit, strength work, and a more comfortable saddle can all help spread the load and calm things down.

I’ve found that small changes (a few millimeters of saddle height, a slightly shorter stem, a different bar shape) can be the difference between “my back always hurts” and “I can ride again tomorrow.”


5. Respiratory & Heat-Related Problems

Depending on where you ride, your lungs and your cooling system may take a beating. Dust, pollen, wildfire smoke, and city pollution can make breathing harder than it should be. Add heat and humidity on top of that, and you’ve got a dangerous combo.

Common issues include:

  • Allergy flare-ups and tight chest from pollutants
  • Dehydration from underestimating fluid needs on long rides
  • Heat exhaustion or even heat stroke in extreme conditions

Some simple rules I try to follow:

  • Start rides earlier during hot months and avoid the brutal afternoon sun.
  • Sip water steadily instead of “chugging when I’m already thirsty.”
  • Use electrolyte drinks on longer or hotter rides.
  • Know the early signs of heat illness: dizziness, nausea, headache, confusion, chills in hot weather.

If you ever feel weak, disoriented, or “off” in the heat, stop riding immediately, get in the shade, drink fluids, and cool your body. No mileage goal is worth a hospital visit.

Recovery & Health Tools That Keep Me Riding

Training is only half the story. Recovery and honest tracking are what keep senior cyclists healthy enough to enjoy the miles.

Simple tools like these make it easier to recover, spot trends early, and keep cycling as a lifelong habit instead of a short-lived phase.


Stay Vigilant, Stay on the Bike

The big takeaway is simple: being fit is a blessing—but it’s not a shield. Cycling does wonders for your heart, joints, weight, and mental health, but it doesn’t erase the need for common sense and medical care.

Listen to your body. Don’t ignore warning signs just because you “ride a lot.” Make time for rest and recovery. Use gear that protects your head, joints, skin, and visibility. And when in doubt, talk to your doctor.

Cycling is meant to be a lifelong joy. Taking your health seriously is what lets you keep rolling.
