Preparing for running 20km

Those who are taking part in a competition for the first time should be aware that adequate physical preparation is essential for running 20 km, i.e. the leg and thigh muscles must be tonic, like the abdominal muscles and those of the back and arms.

The first objective is to run 7 km, then 14 km, and finally 20 km.

After completing the first training sessions and having reached a certain level of autonomy, the 7 km becomes a distance to cover quickly. To run short and fast races is a useful training to improve performance. Being able to run 14 km means having reached a good level, and above all it increases the awareness of being able to cross the 20 km finish line. To be able to run the 7 and then the 14 km is a main objective to be able to run the 20 km easily.

To be sure you can, achieve your goal of 20 kms, you don’t necessarily have to run all those kilometres, you just have to be able to run at least 16-18 km during your training. Then it is the sum of the km run during the training sessions during the weeks that will allow to reach the end of the race.

During the preparation of your 20km in the 6 weeks before the competition you should run at least three times a week, if possible on mixed courses. It is advisable to organize the training in cycles of two weeks of intense training and one week of regeneration. During weeks of intense training you can train over distances varying between 10 and 18 km. During training on weekdays, we usually run 8-10 km. However, Sundays are devoted to longer training sessions. During the regeneration week, the length of the training course varies between 6 and 8 km maximum.

In order to manage the rythm of my foodsteps during the competition, the best strategy is to learn how to manage the pace of your run based on your breathing rhythm, in addition to your GPS watch

Don’t forget the most important thing: running is a time of joy and fun. We have always believed in the positive influence of sports activity on daily life, and together with all the participants in the « 20 km de Paris » race, we want to share the message of sport lived with joy, without the stress of competition.

Dehydration VS performance

The human body is about 60% water. The water requirement for a sedentary adult person is 1.5 to 2 litres per day. Of course the requirement is increased for the sportsman, according to his activity. Dehydration greatly affects your performance, not only physically, but also intellectually.

We know that a weight loss of 2% due to dehydration reduces physical capacity by 20%!

And if the water loss increases further, unpleasant pains can then appear: digestive problems, vision problems, reaction and concentration problems, etc.

Tip: Drink before you get thirsty! The body begins to dehydrate long before the thirst signal. It is better to drink throughout the day, in small quantities, than only with meals. During any physical activity, it is essential to drink a lot, even in small quantities, throughout the effort.

10 golden rules to stay hydrated

Before exercise, and especially in the last half hour before exercise, drink up to half a litre of water (3 glasses) in small sips.

During the physical effort, drink in small sips and in reasonable quantities so as not to overload your belly and avoid any side stitches. Also avoid soft drinks because of bloating.

For an effort of less than 30 minutes, no need to drink. For an effort of 30 minutes to 3 hours and of high intensity, it is preferable to drink very regularly every 15 to 20 minutes, and depending on the degree of sweating, between 0.5 and 1.5 litres of water per hour. For an effort longer than 3 hours (very long duration), drinks will be taken every 30 minutes to 1 hour, at a rate of 0.4 to 1 litre of water per hour.

If it’s hot and you pass near a water source, don’t hesitate to spray yourself (especially your legs) with water to keep your body at a normal temperature.

Don’t wait until you’re thirsty to drink. If that’s the case, it’s already too late. Anticipate events and drink a little after 15 minutes.

Drink regularly after exercise. It is urgent to restore the water capital as well as the energy reserves, as soon as possible after the physical effort: 0.5 to 1.5 litres per hour and in a fractioned manner.

Even if you are “dying” of thirst, do not drink a big quantity in one go to avoid, once again, any risk of stomach upset.

Make sure you compensate for the loss of water and essential nutrients due to your effort by drinking regularly to delay muscle fatigue.

The water you drink should be at a temperature of 10 to 15°C. If your drink is too cold or even icy, it may cause intestinal problems.

Depending on the intensity of your practice and the outside temperature, your daily water consumption should be between 2 and 4 litres.


But drinking isn’t enough. During a physical effort, the body loses a lot of minerals through sweating. It is therefore important to compensate for this loss.

This is where mineral-rich waters come into play, efficiently hydrating the body.


A sparkling natural mineral water, ST-YORRE is particularly recommended for sports. Mineralized (4774 mg/l): it allows a good hydration,

a good recovery and it helps to reduce the acidosis of the body, acidosis which can cause cramps.

Conclusion: without water no performance is possible!

Dehydration is the n°1 factor in failure, along with hypoglycemia, observed on all sports fields, especially in hot weather.

Eating well before a race: the advice of Bio c’ Bon !

Naturopaths recommend qualitative and organic food that respects the physiology of our digestive system. The benefit of this food hygiene is that it is “hypotoxic”, i.e. it does not clog the body.

Therefore she is:

  • Detoxifying
  • Antioxidant
  • Deacidifying and digestible
  • Revitalizing and energizing

This diet will help prevent disorders that may be associated with physical efforts:

  • Muscle and tendon disorders: cramps, aches and pains, inflammations
  • Joint disorders: pain, fatigue, wear and tear, injuries
  • Circulatory disorders: feeling of heavy legs, tingling
  • Digestive disorders: nausea, acidity, hypoglycemia related to exercise
  • Fatigue, exhaustion, poor recovery
  • Oxidative stress, cell aging
  • Side effects linked to taking industrial supplements (protein drinks, energy drinks that are too sweet) which end up unbalancing the body.

Specific food

According to naturopathic doctors, the diet of man is composed as follows:

80% raw vegetables:
Fresh and juicy fruits (apples, cherries, plums, melons, figs, oranges), dried fruits (dates, figs, apricots, prunes), fatty fruits (almonds, cashews, hazelnuts, walnuts), oil seeds (sunflower, squash, sesame or flax seeds), sprouted seeds, green vegetables (cabbage, zucchini, green beans, cucumber, fennel), root vegetables (carrot, celery, beet), herbs (onions, garlic, thyme, rosemary), herbs (parsley, chives, basil), leaves (salad), sprouts (spinach, purslane, watercress), seaweed, etc.

20% of animal by-products :
Naturally fermented cheeses, curds, shells, eggs.

Of course this diet depends on the physiology of our digestive system and must be adapted to the vitality, lifestyle and health of each individual. Thus, cooked foods, starchy foods and meat can be added to this basis. On the other hand, will be avoided: tea, coffee, chocolate, alcohol, sugars and industrial food, microwave cooking and frying.

We can also recommend foods suited to supplement the diet of the athlete and make up the shortfall: spirulina, quinton, turmeric, acai, barley grass.

For sports efforts

The good sugars that are useful for exercise can be found in fruits and dried fruits: bananas, dates, figs, not forgetting fruits which are rich in good fatty acids, such as avocados, almonds, coconuts.

Proteins will be provided by animal by-products as well as by spirulina, almonds, green leafy vegetables, avocados, hemp seeds.

Thanks to this type of food, digestion is quick and easy. Runners don’t need to eat a meal 4 hours before the competition to have digested well. The meals taken before the effort are ideally consists of dates, fresh fruit and banana.

In practice

Before the effort and during the race we will be able to consume these foods in various forms:

Mixed to obtain vegetable milks :
Cashew + banana + date
Almond + agave

In bars or pellets :
Prunes + sprouted wheat + agave + almond + sunflower seeds
Goji berries + cashew nuts + honey + coconut

Energy drinks:
Maca + guarana + carrot juice
Orange juice + spirulina

In a smoothie:
Pineapple + banana + barley grass
Green leaves + bananas + dates

The main meals will consist of colourful raw vegetable salads, cheeses, eggs or yoghurt. You can add cooked vegetables, some gluten-free potatoes or rusks, buckwheat pancakes, and steamed fish. For dessert, a few prunes or baked apples.

This type of diet can be introduced by gradually reducing starchy foods and increasing the proportion of fresh foods in the form of raw vegetables, and replacing the usual snacks with fresh fruit, fatty fruit and dried fruit.

Of course, it is best to seek advice from a naturopathic doctor who will personalize your diet. Note that a detox cure, which will allow you to get rid of harmful habits and to start fresh is strongly recommended before setting up a new food hygiene.
