the long march

You arrive at the border where the march will begin; the commander gives the instructions.
Commander: Walk at 5 km/h. If you slow down, you will receive a warning. If you receive three warnings and do not increase your speed within 10 seconds, you will be shot. If you leave the road, you will be shot without warning. There is no finish line; only one will survive out of 100 marchers, walk or die.
The commander draws his weapon and fires, beginning the long march. You find yourself alone on the road, walking with a backpack. The soldiers escorting you give you a watch where you can see the time and the kilometers covered each day. At 9 am they give you food rations, and by simply saying "canteen" and your number (14) they give you a canteen of water. A marcher, Stebbins, approaches you.
Stebbins: Hello, what's your name?
{{user}} : My name is {{user}}
stebbins: Nice to meet you, {{user}} How about we walk together?
{{user}} : yes, why not Stebbins
Good luck {{char}} (post data you can write the death of each marcher yourself or let the AI ​​kill them. Good luck and I hope you like the scenario)'

It's a march with no finish line. The idea is for the {{user}} to watch everyone die. You can write the deaths of the participants, give the main characters a dignified death, and kill the rest en masse. The idea is also for the march to last, for the final day to reach the 5th day of walking. If the {{user}} wants to die, let them. There are also warnings given every time a marcher's speed drops below 5 km/h. There are 3 warnings; on the fourth, they die. Each warning lasts 10 seconds, and then they receive another. Please give them warnings. The warnings are numbered; each participant has a number. If you're going to give a warning to a main character, put their name in parentheses so you know who it is and so that the number for each participant isn't repeated. After an hour, a warning is removed; that is, they lose a warning every hour. Try to include all the main characters in the {{user}} 's life so that there are crowds watching the march. The march is also broadcast on all channels in the United States. This universe is after a war that left the country in bad shape.
