How to Run Faster Without Getting Tired
You want to run faster, and you want it to feel easier. Most runners try to get there by running harder, more often. That’s usually why they stall.
How to run faster comes down to 4 things, in this order: how you split your easy and hard running, strength training, a little speed work, and small tweaks to your form. Gear and conditions come last.
Run Slower to Run Faster
Elite endurance athletes in running, rowing, cycling and skiing spend roughly 80% of their training time at low intensity and about 20% going hard. Physiologist Stephen Seiler, who mapped this out, found the same pattern across sports and countries.
Most recreational runners do the opposite. Every run lands at a medium effort, stuck in the middle: too hard to recover from, too easy to build much.
Does the exact split matter? For elite athletes, plans built mostly on easy running with a small amount of hard work tend to beat threshold heavy plans. For recreational and trained runners, a 2025 review found every approach improved performance by a similar amount. So for you, the precise ratio isn’t the point. The point is that easy days stay easy, so hard days can actually be hard.
How to Apply It
- Count time, not distance. If you run 4 times a week and 1 run is hard, that’s roughly 75/25. That’s fine.
- Easy runs: you can talk in full sentences the whole time. If you can’t, slow down, even if the pace feels embarrassing.
- Hard runs: tempo runs, intervals, hills or fartleks. Show up fresh enough to hit the paces.
Easy running builds your aerobic base, meaning more mitochondria, more capillaries and tougher tendons, with very little fatigue. Hard running pushes your VO2 max and your ability to hold faster paces. You need both, in the right amounts.
Running Economy: Your Fuel Efficiency
If VO2 max is the size of your engine, running economy is your fuel efficiency. It’s how much oxygen it costs you to hold a given pace. Among runners with a similar VO2 max, economy explains a lot of the difference in race times. 2 runners with the same engine can finish minutes apart.
Economy improves with years of running, strength training and a few form habits. Most of the gains come from the first 2.
Should You Change Your Cadence?
Probably less than you’ve heard. The idea that everyone should run at 180 steps a minute is a myth. Cadence rises with speed, and even elite runners vary widely at easy paces.
Research suggests the cadence you choose naturally is close to your most economical one. Where a cadence bump earns its place is overstriding. Raising your cadence by 5 to 10% shortens your stride and reduces the load on your knees and hips, which helps if your foot lands far out in front of you.
- Count every time your right foot lands for 30 seconds on an easy run, then multiply by 4
- Set a metronome app 5% higher and use it for part of an easy run
- If it feels harder, not easier, back off
Watch metrics like vertical oscillation (how much you bounce) and ground contact time get a lot of attention. Chasing them directly rarely helps. They tend to improve on their own as you get fitter and stronger.
Strength Training Makes You Faster
Runners used to avoid the weight room, afraid it would make them slow or bulky. The research says otherwise. A 2023 meta-analysis in Sports Medicine found strength training improved running economy in middle and long distance runners. Heavy lifting helped more at faster speeds, plyometrics helped at slower speeds of about 12 km/h or below, and combining the 2 produced the biggest effect.
It works because stiffer, springier tendons return more energy with each step, stronger legs work at a smaller share of their max with every stride, and you hold your form longer when you’re tired. And no, it won’t make you bulky. Anyone who’s tried putting on size while running knows how hard that is.
| Variable | What to do |
|---|---|
| Frequency | 2 to 3 sessions a week, 1 to 2 in race season |
| How long | Most studies ran 6 to 14 weeks before economy improved |
| Exercises | Squats, deadlifts, step-ups, split squats, calf raises |
| Load | Build from bodyweight to heavy sets of 3 to 6 reps |
| Plyometrics | Jump rope, pogo hops, jump squats, bounding. Depth jumps only once you’re experienced |
Add Some Speed Work
- Strides. 4 to 6 relaxed accelerations of 20 to 30 seconds after an easy run, twice a week. They teach you to run fast without the fatigue of a full interval session.
- Hill repeats. 6 to 10 hard efforts of 30 to 60 seconds uphill, walking or jogging back down. Hills build power and are easier on your legs than flat sprints.
- Low level plyometrics. Jump rope and pogo hops train quick, springy ground contact.
When you’re tired, your cadence drops, you bounce more and your feet stay on the ground longer. Strength and speed work help you hold your form deeper into a run, which is where races are won or lost.
Conditions and Gear
| Factor | Effect |
|---|---|
| Temperature | Cooler conditions usually mean faster times |
| Humidity | Raises heat stress and makes the same pace feel harder |
| Wind | A headwind costs more the faster you run |
| Shoes | Carbon plated super shoes improved economy by around 4% in lab studies of fast runners. The gain may be smaller at slower paces |
These matter on race day. They don’t replace training.
How to Run Faster in 12 Weeks
| Weeks | Running | Strength | Speed |
|---|---|---|---|
| 1 to 4: Foundation | Mostly easy, 1 harder run a week | 2 bodyweight sessions | 4 to 6 strides after 2 easy runs a week |
| 5 to 8: Development | Mostly easy, 1 to 2 harder runs (tempo or hills) | 2 weighted sessions | Strides plus weekly hill repeats |
| 9 to 12: Sharpen | Mostly easy, 2 harder runs including race pace work | 2 sessions, add plyometrics | Race pace efforts and fueling practice |
Take an easier week every 4th week if you’re feeling beaten up: cut your volume by a third and keep a few strides in.
Mistakes That Keep You Slow
- Running every run at the same pace. Usually a medium pace that’s too hard to be easy and too easy to be hard.
- Chasing pace on easy days. Your watch says 5:45 per km, your breathing says slow down. Listen to your breathing.
- Racing your workouts. Intervals should end with you feeling like you could do one more, not collapsed on the track.
- Dropping strength work when life gets busy. 1 short session a week is enough to hold on to most of what you built.
- Adding mileage in big jumps. Build gradually and hold a new volume for a couple of weeks before you add more.
What Matters Most
- Keep easy runs easy and hard runs hard
- Lift 2 to 3 times a week
- Add strides and hills
- Make small form tweaks only if you need them
- Worry about shoes and conditions last
None of this is a shortcut. It’s the order that works. Get the first 2 right and you’ll be faster in 12 weeks without every run feeling like a fight.
