3 Ways to Boost Your Endurance Training

Endurance training is about much more than collecting miles. If you want to feel stronger, move better and stay in the game for years, your training needs more than just another steady run or ride.

Events such as tough mudder, hyrox, marathons, ultra events and triathlons are now part of everyday conversation. You do not need to be an elite athlete to sign up, and that is part of the attraction. These events give you a clear goal, a reason to train and a powerful sense of achievement when you cross the line.

To get the most from your effort, and to protect your body along the way, you need three pillars in place:

Strength
Mobility and recovery
Supportive nutrition

At Foundry, this is how we help people train smarter, not simply harder.

Strength For Endurance Performance

Endurance training is repetitive by nature — step after step, pedal stroke after pedal stroke. Over time, this places a heavy load on your joints and soft tissues.

Strength training gives your body the support structure it needs. When you build strength in the right areas, you improve:

Joint stability and resilience
Running or cycling economy
Power output on hills and sprints
Overall longevity in your sport

For most people, the priority is the posterior chain. This includes the muscles through the back, glutes, hamstrings and calves, along with the deep muscles around the hips and trunk. These areas help you maintain good posture and technique, especially when fatigue sets in.

At the same time, you want to keep your classic endurance muscles, such as the quads and hip flexors, strong but not overloaded. Balanced strength through the whole system is the goal.

Strength In The Gym

You do not need a bodybuilder programme. A few well-chosen movements, done consistently and with good form, will take you a long way.

Focus on these main patterns.

Squat variations such as the goblet squat or the front squat
Hinge variations, such as the Romanian deadlift or hip thrust
Lunge and split stance variations, such as reverse lunge or split squat
Step variations such as step-ups or step-downs
Rowing patterns to support posture
Pressing patterns for upper body strength
Loaded carries for full body stability

For your trunk, think about resisting movement rather than chasing hundreds of sit-ups. Exercises such as dead bugs, side planks, cable holds, and loaded carries all build functional strength for endurance.

Minimum Strength

When you are already training for an event, time is limited. The good news is that you do not need to live in the gym to see benefits.

A simple starting point is:

Two strength sessions per week
Thirty to forty-five minutes per session
Six to eight exercises per session

Work mainly in the six to twelve rep range for two to four sets. Pick a load that feels challenging but still allows you to keep two or three reps in reserve at the end of each set. You should feel that you are working hard without grinding.

Move with control on the way down, then drive with intent on the way up. Quality of movement matters more than chasing the heaviest possible weight.

Strength Sessions Around Endurance

The key is to place your strength work so it supports your endurance training rather than competing with it.

For a first-time 10k runner, a simple weekly layout might be:

Monday: Strength
Tuesday: Easy run
Wednesday: Rest or light mobility
Thursday: Intervals or tempo run
Friday: Strength
Saturday: Longer easy run
Sunday: Rest or relaxed walk

For a busy half-marathon runner or cyclist:

Two strength sessions on days when your endurance work is lighter
One harder endurance session on a separate day
One longer session at the weekend

In peak event weeks, you might reduce the weight on the bar or drop one strength session. The aim is to maintain strength rather than push for big gains right before your race.

Mobility, Soft Tissue and Recovery

Good endurance performance is not just about strong muscles. Your joints also need to move smoothly through the ranges your sport demands.

Modern life does not always help. Time at a desk, on trains and in meetings can leave you stiff through the ankles, hips and mid back. These areas are essential for efficient running and cycling techniques.

Regular mobility work keeps these joints moving well, which can:

Improve technique and comfort
Reduce the risk of niggles
Help you feel better in day-to-day life

A simple daily routine might include ankle rocks, hip circles, gentle lunges and rotations through the upper back. Five to ten minutes on most days is often enough when combined with good strength work.

Soft Tissue Work

Soft-tissue work, such as massage or foam rolling, helps you care for the muscles that do the most work during endurance training.

Functional areas to focus on include:

Calves and shins
Quadriceps and hip flexors
Glutes and outer hip muscles
Hamstrings
Soles of the feet

Massage can be an excellent option when time and budget allow. Foam rollers, massage balls or even a hockey ball under the foot can be very effective between sessions.

Aim for short, regular work rather than occasional, very long and painful sessions. Sixty to ninety seconds per muscle group is usually enough. The goal is to ease tension, not to brace and hold your breath.

Warm Up And Cool Down

A good warm-up does not need to be complicated. You are trying to raise your body temperature slightly, wake up key muscles, and prepare your joints for the upcoming movement.

For example:

A few minutes of easy movement, such as walking or gentle cycling
Dynamic movements such as leg swings, lunges and arm circles
A few short strides or pick-ups before a running session

After your session, give yourself a few minutes to cool down. Walk, stretch gently and slow your breathing. This helps your body shift into recovery mode and often leaves you feeling fresher for your next session.

Recovery Habits

The biggest recovery tools are free.

Sleep is one of the most powerful performance enhancers you can use. Most people benefit from seven to nine hours per night. A calmer pre-bed routine, a cool, dark room and consistent bedtimes can make a noticeable difference to energy and mood.

Light movement between harder sessions also helps. Walking, easy cycling or gentle mobility work all support blood flow and recovery without adding extra stress.

Finally, remember that training is part of a wider life. Busy weeks at work, travel, and family demands all add to your overall stress. In those weeks, it is often smarter to reduce training volume slightly and protect sleep and nutrition, rather than pushing on regardless.

Nutrition That Supports Endurance

Endurance training places high demands on the body. Supportive nutrition helps you meet those demands while staying healthy and lean.

A simple base that works well for many people includes:

Regular meals built around lean protein
Plenty of vegetables and some fruit
Healthy fats from sources such as olive oil, nuts, seeds and oily fish
Clever use of carbohydrates around training based on your workload

Protein supports recovery and helps you maintain muscle mass during heavy training blocks. Vegetables and fruit provide a wide range of vitamins, minerals and fibre.

Try not to fall into the trap of using every session as a reason to overeat highly processed foods. It is perfectly fine to enjoy treats; however, your everyday pattern should support your goals rather than work against them.

Fuelling Long Sessions

For sessions shorter than around sixty minutes at moderate intensity, many people can perform well with a normal pre-session meal and some water.

As sessions become more prolonged or more intense, you will likely benefit from adding extra carbohydrates before and during training.

Useful strategies include:

A balanced meal two to three hours before a key session, with carbohydrates, protein and a small amount of fat
A small snack such as a banana, toast with nut butter or yoghurt with fruit one to two hours before
Sips of a drink or small snacks such as dried fruit or simple energy products during longer efforts

Hydration matters too. Drinking regularly through the day, rather than trying to catch up in one go, often works best. In hotter conditions or for longer events, an electrolyte drink can help you replace what you lose through sweat.

Gut Friendly Strategy

Gut health is an essential yet often overlooked factor in endurance performance. Many athletes can tell stories of stomach problems that cut their races short.

Common issues include using new products on race day or consuming more carbohydrates than the gut is used to handling. The solution is to practise your race nutrition during training.

Choose a simple fuelling plan, test it on your longer sessions and adjust as needed. Some people do well with sports drinks and gels. Others prefer more natural options such as bananas, dried fruit or flapjacks. There is no single correct answer, only what works for your body.

On race day, stick to what you have already tested. Your gut will thank you.

Supplement Use

Food should always come first. Supplements can support a solid diet, but they cannot replace it.

For some people, a protein powder can be a convenient way to increase protein intake, especially after training or on busy days. Depending on your diet and lifestyle, nutrients such as vitamin D may also be worth considering.

If you are thinking about supplements, use them to fill genuine gaps rather than as a quick fix. When in doubt, focus on regular meals, good sleep and consistent training first.

Endurance Training Pitfalls

Doing the same route, at the same pace, every time can only take you so far. Without variety, your body adapts, then plateaus.

A more effective approach includes a mix of easier and harder sessions. Some days focus on distance, others on pace or hills, and some are there to keep your legs ticking over.

Ignoring Strength and Mobility

Many endurance athletes delay strength training until after an injury. A better option is to think of it as part of your base, just as important as your long run or ride.

A couple of weekly sessions, along with regular mobility work, often reduce niggles and help you feel more resilient. It is a small investment of time that pays off over the long term.

Under Fuelling

Combining heavy endurance training with a very aggressive diet can cause problems. Low energy availability can affect hormones, recovery, mood and immunity.

If you notice constant fatigue, poor sleep, low mood, unusual hunger or frequent illness, it may be worth reviewing your energy intake and training load with a coach or nutrition professional.
