Speed Training for Endurance

Endurance training remains as popular as ever. From first-time 10k runners to seasoned triathletes, more people are setting performance goals that demand structure, discipline and consistency.

Clocking the miles is essential. There is no substitute for building an aerobic base. However, if all your training sits at one steady pace, progress will eventually stall. You may feel fitter, yet your times refuse to shift.

Speed training is often the missing piece.

When you become stronger and faster over short distances, you become more efficient over long ones. That means improved race times, better running economy and a greater sense of control when fatigue creeps in. It also makes the process more enjoyable. Seeing tangible progress keeps motivation high.

At Foundry, we approach endurance speed training as part of a complete system. Strength, body composition, posture, technique and structured sprint work all play a role.

Speed Matters For Endurance

Speed work improves neuromuscular coordination. In simple terms, your body becomes better at producing force quickly and efficiently.

When you can generate more force with each stride or pedal stroke, you need fewer of them to maintain a given pace. Over time, this reduces the energy cost of movement at submaximal speeds. Your comfortable pace becomes faster without feeling harder.

There is also a psychological benefit. Knowing that you can run faster than race pace builds confidence. When the final kilometres get uncomfortable, you are not stepping into unknown territory.

Breaking Through Plateaus

Many endurance athletes train in what feels like a comfortable middle ground. Not easy enough to recover fully, not hard enough to create real adaptation.

Without variation in intensity, the body adapts and progress slows. Introducing structured speed work forces new adaptations. Your heart, lungs, muscles and nervous system are challenged in different ways, leading to measurable improvements.

Build Strength Before Chasing Speed

Speed is built on strength. The stronger you are relative to your bodyweight, the more force you can apply to the ground.

This does not mean training like a competitive powerlifter. It does mean taking strength training seriously. A robust posterior chain, strong hips and a stable trunk allow you to transfer force efficiently.

When fatigue sets in late in a race, strength is often the difference between holding form and falling apart.

Gym Exercises

A simple strength programme for an endurance athlete might include:

Squat variations such as goblet squat or front squat
Hinge variations such as the Romanian deadlift or the trap bar deadlift
Split squats and lunges for single-leg control
Step-ups to mimic running mechanics
Rowing movements to support posture
Anti-rotation and anti-extension trunk work

Two sessions per week, focusing on controlled but challenging loads, is sufficient for most people. Aim for quality movement, full range of motion and good technique.

Introduce Explosive Work

Once a base level of strength is in place, low-level explosive exercises can be introduced.

Medicine ball throws, low box jumps, and short hill efforts are effective options. These movements train the body to produce force quickly, which carries over to improved running or cycling speed.

Keep volume low and intent high. Full recovery between sets ensures quality remains the priority.

Optimise Body Composition

Speed is not just about how much force you can produce. It is also about how much mass you are moving.

Carrying excess body fat increases the energy cost of movement. Improving your power-to-weight ratio often leads to noticeable gains in speed without increasing overall training volume.

The goal is not extreme leanness. It is about finding a body composition that supports performance while maintaining health and energy.

Nutrition Strategy

A few simple principles go a long way:

Prioritise adequate protein to maintain muscle mass
Include carbohydrates around harder sessions
Focus on whole foods and regular meals
Avoid aggressive calorie restriction during heavy training blocks

Under-fuelling is a common mistake among endurance athletes trying to improve speed. Chronic low energy availability can harm recovery, hormone balance and performance.

Improvements in body composition should support training, not undermine it.

Improve Posture and Structural Balance

Good posture allows efficient breathing and effective force transfer.

Long hours sitting at a desk can lead to tight hip flexors, rounded shoulders and limited movement through the mid back. Over time, this affects stride mechanics and breathing efficiency.

Improving posture is not about standing stiffly. It is about balanced strength and mobility, so your body can move freely.

Corrective Strength Focus

Endurance athletes often benefit from strengthening:

Glutes and hamstrings
Upper and mid back
Deep trunk muscles
Hip stabilisers

Exercises such as lunges, deadlifts and rowing variations address many of these areas. Combined with regular mobility work for the hips and thoracic spine, this supports better alignment and more efficient movement.

Breathing Drills

Breathing is often overlooked.

Simple drills such as controlled nasal breathing during warm-ups, slow exhalations after intervals and relaxed diaphragmatic breathing before sleep can improve recovery and performance.

Efficient breathing supports oxygen delivery and helps manage stress during high-intensity efforts.

Refine Technique For Faster Running

Small improvements in technique can produce significant gains in speed.

Think about driving your leg back into the ground rather than reaching too far in front. A powerful backward push improves propulsion and reduces braking forces.

Arm drive also matters. Coordinated, purposeful arm movement helps maintain rhythm and balance at higher speeds.

Drills To Reinforce Good Form

Incorporate simple drills before speed sessions:

A skips to promote coordination
High knees for rhythm
Bounding for controlled power
Short strides at a controlled pace

These drills prepare your nervous system for faster running and reinforce good movement patterns.

Coaching Feedback

Even experienced athletes benefit from feedback.

A trained coach can spot inefficiencies that are difficult for you to feel. Small adjustments in posture, cadence or arm action can unlock meaningful improvements.

Occasionally, filming your stride can also provide useful insights.

Add Structured Sprint Work

True speed development requires sprinting.

Start with short distances, such as 10 to 30 metres. Focus on maximal effort with complete rest between repetitions. These sessions are not about feeling exhausted. They are about producing quality efforts.

For example:

Six to ten sprints of twenty metres
Full walk-back recovery
Two to three sets with longer rest between sets

Quality over quantity is the rule.

Tempo and Threshold

In addition to short sprints, controlled harder efforts improve your ability to sustain faster paces.

Tempo sessions just below race pace and threshold intervals slightly above it help increase lactate tolerance and aerobic capacity. These sessions should feel challenging but controlled.

One session per week is sufficient for most recreational athletes.

Hill Training

Hills are an excellent way to build speed safely.

Running uphill reduces impact forces while increasing muscular demand. Short hill sprints build strength and speed together. Longer hill efforts improve endurance and mental resilience.

Start conservatively and build volume gradually.

Speed Training Mistakes

Introducing large volumes of sprinting without preparation increases the risk of injury. Build strength first, then gradually layer in speed.

Treating Sprints As Conditioning

Sprint sessions should not feel like circuit training. If your pace drops significantly, you are not resting enough.

Full recovery preserves quality and reduces the risk of injury.

Neglecting Recovery

Speed training increases stress on the nervous system. Adequate sleep, good nutrition and sensible programming are essential.

More is not always better. Well-placed intensity within a balanced week is what drives progress.

Sample Week Combining Endurance and Speed

For a 10k focused athlete:

Monday: Strength session
Tuesday: Interval session
Wednesday: Easy run
Thursday: Strength session
Saturday: Long run
Sunday: Rest

For a triathlon athlete:

Two strength sessions per week
One short sprint session
One threshold session
One longer endurance session
Additional low-intensity technical work as needed

This structure allows speed to complement endurance rather than compete with it.

Personal Coaching At Foundry
