Most of us, we just pull on a top, grab a pair of shoes and out we go – straight into a run. Even when we’re out running in a group – we mostly chit chat before running – or does the dash to the toilet count as warm-up?
For those who do some semblance of a warm up – it is usually a couple of stretches and that’s about it.

Question is – do we really need to do any warm-up before running? And if required – what and how to do it?
Answer is….. It depends. If you are just going for a routine run or jog and not doing any speedwork – generally the first 5 to 10 minutes can serve as the warm up. But if you are going for a speedwork session – like a tempo run or an interval, it is critical to do some form of warm up. Nevertheless regardless of the type of run, it is good practice to start off with some warm up. There are many reasons for this:
1. Raises Your Body Temperature
A proper warm-up increases your core and muscle temperature by 1–2°C. Warmer muscles:
- Contract more efficiently.
- Generate more power.
- Are less prone to strains and tears.
- Improve flexibility without excessive stretching.
2. Increases Blood Flow
As your heart rate gradually rises, more oxygen-rich blood reaches your working muscles.
This means:
- Better oxygen delivery.
- Faster energy production.
- Less feeling of heaviness during the first few kilometres.
Ever started a race feeling like you’re dragging two sacks of rice? That’s often because your body hasn’t switched into exercise mode yet.
3. Wakes Up Your Heart and Lungs
Instead of shocking your cardiovascular system with an immediate sprint, a gradual warm-up allows:
- Heart rate to rise progressively.
- Breathing to become more efficient.
- Blood pressure to adjust safely.
This is especially important for older runners or anyone with heart conditions.
4. Lubricates Your Joints
Movement stimulates the production and circulation of synovial fluid—the body’s natural joint lubricant.
The result:
- Smoother joint movement.
- Reduced stiffness.
- Better mobility in the hips, knees and ankles.
It’s like applying fresh grease to bicycle gears before a long ride.
5. Activates the Right Muscles
Many people spend most of the day sitting.
A warm-up “switches on”:
- Glutes
- Core muscles
- Hip stabilisers
- Calves
When these muscles activate properly, they help prevent other muscles from overworking and reduce the likelihood of injuries like IT band syndrome or runner’s knee.
6. Improves Running Form
Dynamic movements reinforce good mechanics by encouraging:
- Better stride.
- Higher cadence.
- Improved balance.
- Efficient arm swing.
Your body remembers movement patterns better when it’s already moving.
7. Sharpens Your Brain
Running isn’t just about legs.
A warm-up:
- Improves reaction time.
- Increases focus.
- Helps mentally prepare for the session ahead.
Elite athletes often say the warm-up is when they transition from “work mode” to “race mode.”
8. Reduces Injury Risk
While no warm-up can eliminate injuries entirely, research suggests that dynamic warm-ups reduce the risk of muscle strains and improve readiness for activity.
Common injuries that may be less likely include:
- Calf strains
- Hamstring pulls
- Achilles tendon irritation
- Muscle cramps
9. Helps You Run Faster
Many runners skip the warm-up because they’re trying to “save energy.”
Ironically, the opposite often happens.
A good warm-up helps you:
- Reach your target pace sooner.
- Feel less breathless.
- Maintain a stronger pace.
- Delay fatigue.
With so many plus and no minus, do remember to do your warm up before starting every run.
That’s why elite runners don’t stand still until the starting gun—they’re usually jogging, doing drills and strides behind the start line.
