Minimalist10 mistakes new runners make
Most beginner running mistakes come down to doing too much, too fast, too soon. The good news is that each one has a simple fix, and avoiding just the first three will make your first months of running feel far easier.
Here are the ten we see described most often, roughly in order of how much trouble they cause.
1. Running every run too fast
New runners tend to have one speed: “as fast as I can manage for this long.” That makes every run hard, recovery slow, and progress frustrating.
The fix: slow down until you can speak in full sentences. Most of your running — experienced runners often say around 80% — should feel easy. If that seems impossibly slow, it is normal; read our guide to easy effort and zone 2 for why it works.
2. Increasing distance too quickly
Your heart and lungs adapt within weeks. Tendons, bones and connective tissue take months. That gap is why a beginner can feel great, double their weekly distance, and then end up with sore shins or knees.
The fix: increase your total weekly distance or time gradually. The widely used “10% rule” is a rough guide rather than science, but the spirit is right: small steps, and every third or fourth week, hold steady or ease back.
3. Skipping rest days
Enthusiasm is great. Running five days in a row in your second week is not. Your body gets stronger during recovery, not during the run itself.
The fix: start with three runs per week with a day between each. Easy walks on the days in between are fine and helpful. Our guide on how many days a week to run explains when to add more.
4. Refusing to walk
Many beginners believe walking means failing. So they push through, run themselves into the ground, and dread the next session.
The fix: plan walk breaks before you need them. The run-walk method is used by beginners and marathoners alike, and it’s one of the most reliable ways to keep running enjoyable.
5. Ignoring pain that changes how you move
Some muscle soreness a day or two after running is normal. Sharp pain, pain that gets worse as you run, swelling, or pain that makes you limp or change your stride is different.
The fix: stop, walk home, and rest. If it doesn’t clearly improve within a few days, see a doctor or physiotherapist. Taking a week off early is almost always better than running through something and losing a month.
6. Wearing worn-out or ill-fitting shoes
You don’t need expensive shoes, but you do need ones that fit and aren’t collapsed from years of use. Old fashion sneakers or shoes that pinch your toes are a common source of blisters and aches.
The fix: get a pair that feels comfortable from the first step, with a thumb’s width of space at the toe. Our guide to choosing your first running shoes walks through what to look for.
7. Overstriding
Reaching far forward with each step, landing on your heel with a straight leg, acts like a small brake on every stride and puts extra load on your knees and shins.
The fix: take shorter, quicker steps, and aim to land with your foot roughly under your body rather than out in front. Don’t obsess over heel versus forefoot landing — just shorten your stride a little and let it feel light. Running slightly slower usually fixes this on its own.
8. Comparing yourself to other runners
Someone at work runs 5K in 22 minutes. A stranger online runs every day. None of that has anything to do with you.
The fix: compare only with your own past weeks. Pace for beginners varies enormously depending on age, weight, background and terrain. If you want context, see what a good beginner running pace is — and notice how wide the normal range is.
9. Eating or drinking the wrong things too close to a run
A big meal right before running, or downing a full bottle of water at the door, is a classic recipe for an uncomfortable stomach or a side stitch.
The fix: leave two to three hours after a full meal, or have a small snack (a banana, a slice of toast) about an hour before. Sip water through the day rather than gulping it just before you head out. More on that in our guide to avoiding a side stitch.
10. Starting with a goal that’s too big, or no goal at all
Signing up for a half marathon in your first month puts you on a timeline your body may not be ready for. Having no goal at all makes it easy to let running slip after a busy week.
The fix: pick something specific and modest. “Run three times a week for a month” or “finish a 5K in eight weeks” is perfect. A monthly distance target can also work well — Minimalist, for instance, lets you set one and shows roughly how much a day you still need, which keeps the target honest without pressure.
A quick self-check
| If you notice… | You might be… | Try… |
|---|---|---|
| You can’t talk while running | Running too fast | Slow down, or add walk breaks |
| Legs feel heavy every single run | Not recovering enough | Add a rest day or an easy week |
| Shins ache after runs | Building too fast, or overstriding | Cut distance back, shorten your stride |
| You dread your runs | Making them too hard | Make two runs a week truly easy |
| You keep skipping runs | Missing a clear plan | Fix days and times in your week |
Key takeaways
- Run slower than you think you should. Easy running builds fitness without wearing you down.
- Build distance gradually and take rest days seriously — your tendons adapt more slowly than your lungs.
- Walking is a tool, not a failure.
- Pain that changes how you move is a signal to stop, not something to push through.
- Compare yourself only with your own past weeks.
