Intervals, tempo runs, strength training and the 80/20 rule that changes everything.
Why you need to train hard.
Full lesson on intensity and running improvement — the secret of runners who break personal records
Why has your pace stopped improving?
Most runners make the same mistake: they always train at the same effort. They go out and run at a "comfortably uncomfortable" pace every day, with no intensity variation. They get stuck in the gray zone — too hard to recover from, too easy to develop speed. The result: stagnation. The body adapts and stops improving.
Running is the constant pursuit of getting better. You want to beat the runner you were yesterday. But for that to happen, you need to challenge yourself. There's no way to improve if you don't train hard. If you only run slow, you'll simply get very good at running slow — your body won't develop the neural and muscular adaptations needed for high-intensity running.
To run faster, you need a plan that combines easy runs (which should be the majority) with specific quality sessions: intervals, tempo runs, hill repeats and progressive long runs. It's smart periodization that transforms average runners into fast runners.
Adaptations that only intensity produces.
There are physiological adaptations that only happen when you train hard — easy training simply doesn't produce them
Lactate threshold
Workouts at and above threshold teach the body to handle lactate accumulation and delay fatigue. This adaptation only happens at intensity.
Running economy
Hard workouts refine your mechanics and efficiency. You spend less energy running at the same pace. It seems contradictory, but to run easier at easy pace, you need to train hard.
Cardiovascular strengthening
The heart pumps more blood per beat, muscles develop more capillaries. This doesn't happen in easy training — it happens at intensity.
Fast-twitch fibers
Only recruited at high intensity. Even in long distances you'll need to sprint, accelerate on curves, hills and at aid stations.
Mental toughness: the race-day edge.
Intensity doesn't just train the body — it trains the mind. Learning to tolerate discomfort is one of the most important skills a runner can develop. When you regularly expose yourself to maximum effort, you learn how your body responds and what you need to do to endure longer.
This psychological resilience builds confidence. On race day, the sensation is already familiar — you've been at that intensity before, you've felt that discomfort. You know you can handle it. This effort regulation is built in hard workouts and carried into every type of race. Your mind becomes tougher and you become more resilient in every kind of run.
The 80/20 rule: polarized training to run faster.
The 80/20 polarization model is the key: 80% of your training is easy and 20% is truly intense. What's meant to be intense is genuinely intense — it should make you suffer, think about quitting, wonder why you're putting yourself through it. It's not moderate. It's hard.
The big mistake is the gray zone. Many runners get stuck at moderate intensities — wanting to show off a "decent" pace on Strava. They never train properly easy and never train properly hard. They live in limbo, stagnant, with no improvement. Easy training should be extremely easy. Hard training should be truly hard.
Easy runs exist to maximize recovery and allow more quality in intense sessions. Quality matters more than quantity. When you run easy most of the time, your quality sessions are truly effective — and that's where speed is built.
Speed workouts that work.
Each quality session has a specific purpose to improve your pace
Short intervals (VO2max)
400m to 1000m reps at 3K to 5K pace with short recovery (always active). Start near 5K pace and work toward 3K pace.
Threshold (Tempo Run)
3-5km blocks or 1-2km reps at threshold pace. For marathoners, longer blocks. For 10K runners, shorter reps. The most important workout for long distances.
Race pace
Training at the exact pace of your target race. Your body needs this experience to know what to expect on race day.
Power and speed
Short 100-200m sprints at high intensity with full recovery. Develops mechanics, power endurance and speed.
Periodization: the plan behind the plan.
Periodization divides your training into phases with different goals. In the base phase, the focus is more volume at low intensity, with occasional strength and speed work. In the specific phase, intensity increases gradually — more threshold and race-pace workouts. In the competition phase, sessions simulate the exact demands of the race.
Gradual progression is key: start with lower volume and lower intensity in hard workouts. Increase intensity first, then the distance of segments. For example, work at 400m until you can't get any faster — then start increasing the distance. Monitor for signs of overload and regularly test your thresholds to adjust training zones.
You're never always the same runner. You're either improving or declining. If you always train at the same paces without testing yourself, you might be stagnant without knowing it. Test yourself regularly and adjust your training paces.
Strength training to run faster.
Muscular strength is just as important as mileage for improving your pace
Squats
Strengthens quads, glutes and core. Fundamental for stride power.
Calf raises
Essential for running economy and preventing shin splints and plantar fasciitis.
Core and stability
Planks, abs and hip work. Maintains posture in the final kilometers when fatigue hits.
Plyometrics
Jumps and high knees. Develops muscle elasticity and more efficient cadence.
Mistakes that keep you from running faster.
If you've plateaued, you're probably making at least one of these
Volume only, no intensity
Many runners add mileage without adding intensity. Volume without quality leads to stagnation after initial gains.
Constant gray zone
Always training at moderate intensity is the worst of both worlds. Neither recovering nor developing speed. Escape the limbo.
Fear of intensity
The irony: well-executed intense workouts strengthen structures and prevent injuries. It's not intensity that hurts — it's poorly dosed volume.
Inconsistent training stimulus
Random workouts without systematic planning. No logical progression, no periodization, no concrete goal.
