Can an athlete take a break in the middle of a marathon to drink water and go to the toilet?

Yes, there are drinking stations along the way, so you can rest and adjust.

A marathon is a long-distance run in which athletes run for more than 2 hours. It's hard work for an athlete to exercise for such a long time. During the marathon, the runners are allowed to take a break, as long as the runners themselves are not afraid of getting unsatisfactory rankings.

Similarly, if an athlete wants to go to the toilet, it is allowed during the competition.

Generally speaking, these marathon runners will prepare their various tasks before starting the race, such as replenishing some energy first, and then adjusting their equipment, seeing if their shoelaces are not fastened, whether their clothes are damaged or uncomfortable, and generally excreting before exercise.

At the same time, when approaching the marathon, do not eat too much food that may cause diarrhea. The reason why we feel a desire to excrete during a marathon is usually due to the fact that the muscles in our body are provided with work, and the reduction of blood supply to the stomach and intestines may make these athletes feel a sense of defecation, and some athletes may even have diarrhea because of it.

Marathon: Runners are allowed to drink water in the middle of the race, but they are not allowed to rest or go to the toilet.

The marathon is an ultra-long-distance race held on public roads, with a total distance of 42.195 km. During the race, the starting point can be set in the athletics field, and most of the running distance is on the road, usually using a turning point route or a circular route, with mileage signs, drink stations and road signs along the way.

There is no rest time in the middle of the marathon, and the marathon route should choose a flat avenue, avoid crossing the iron city, and have an appropriate number of referees, pickets and staff.

Marathon runs should be held in cool climates with temperatures around 10 degrees Celsius, which is conducive to the athletes' ability to achieve excellent results.

OK. There are drinking stations along the way.

It's okay to rest and adjust, but the results won't be too good. Matches have a "closed" time, and if the speed is too slow, it will be "contained".

British marathon star Radcliffe once went to the toilet in the middle of a race and ended up running the whole race. It is necessary to know the toilet settings beforehand.

Of course.

It's half of the run, and the rest is 5 hours before running.

After knowing that there was a person who didn't run according to this schedule and won the first place, he changed his name, he kept running, and when he was tired, he would rest for a few minutes and run again.

Uh··· It's okay to drink water, it's okay to rest! Do you go to the toilet ·· I basically gave up the game!

It is possible to rest. It's okay to give up the game!

Only drinking water, 10 km from a water point.

I don't know.

OK. You can check out the information on the Olympic website.

CaC2+2H－OH→Ca(OH)2+CH≡CH↑

Water with saturated salt water or add some ethanol, aluminum chloride, to reduce foam.

The reaction device is equipped with a separating funnel and a flat-bottomed flask, and a small ball of cotton is added. Energizers cannot be used.

Slowly add saturated NaCl aqueous solution to calcium carbide (Ca2C2) dropwise (because water and calcium carbide are too violent, so it reacts with saturated brine instead).

CaC2+2

H2O=Ca(OH)2+C2H2

Hello, the density of water is 1 ml gram.

So 25 ml is 25 grams.

One pound is equal to 500 grams.

So 25 grams is equal to catties.

Laboratory-made acetylene with calcium carbide saturated saturated saline.

CaC22H2O=

Ca(OH)2

C2H2 reacts with saturated brine instead because water and calcium carbide are too violent.

Laboratory-made acetylene reacts with saturated saline and calcium carbide

cac22h2o

ca(oh)2

C2H2 saturated salt water is used because if distilled water is used, the reaction is too fast and the resulting acetylene is prone to explosion. Saturated salt water has less water, so it is safer.
