What should a marathon runner do if he wants to go to the toilet?

In the marathon, the organizing committee of the contestants will arrange portable toilets for the use of the contestants. The specific interval is uncertain. Generally, the toilet will be arranged for 7 or 8 kilometers. The location and quantity of toilets will be clearly marked in the competition guide provided by the organizing Committee, and players need to remember it in advance.

If a player wants to go to the toilet during the competition, he/she needs to apply to the referee first, and then he/she can withdraw from the competition after getting permission from the referee. After going to the toilet, you need to get the permission of the referee again to return to the position where you left the game and continue the game without being disqualified.

Extended data

Pre-competition preparation:

Many runners will store energy (en: carbohydrate load) a few days before the race, that is, increase carbohydrate intake and store more glycogen in the body. Foods rich in carbohydrates, such as noodles, rice, baked potatoes, vegetables and fruits. The proportion of carbohydrates can even be increased to 70%-90% of the total food intake two days before the competition; At the same time, pay attention to replenish more water to prevent dehydration.

Motor skills:

The technique of marathon running is similar to that of long-distance running. Because the distance is relatively long, and it is carried out on roads with different terrain, there are still some technical characteristics.

When running, the upper body leans forward or stands upright slightly. The strength of the back pedal is small, and the swing of the thigh forward and upward is relatively low. From the appearance, the leg that swings upward after kicking the ground is smaller than that of long-distance running. The landing point of the foot is close to the projection point of the body's center of gravity. First land with the whole foot or the outside of the foot, and then transition to the whole foot. When landing, it should be soft and elastic, and the legs should have good buckling and cushioning. The arms should swing naturally, and the amplitude should not be too large.

When accelerating, sprinting and running uphill, two arms and two legs swing actively, which is beneficial to improve the running speed. Step length and step frequency should be determined according to the training level, height and weight of athletes, and adjusted according to the different terrain on the way to ensure that the whole process can be completed at a relatively uniform speed. The breathing rhythm should be adapted to the running speed, and the exhalation should have a suitable depth.

Marathon movements should be coordinated and labor-saving, and the running speed should be uniform. You should be good at changing your running movements on uneven roads. Marathon runs have a lot of exercise. When running, we must pay attention to the technique and preserve our physical strength, the movement rhythm should be appropriate, and when the muscles are inactive, we should fully relax in order to have a rest. Therefore, in the usual training, athletes should repeatedly understand the movements and master reasonable running techniques in order to continuously improve their sports performance.
