Not right person not right place

That day was about 8 years ago when I was at secondary school at football session at school teacher called me and two other colleagues and tell us that he had to send 3 students to represent school for Athletics games and he hadn't time to choose, that’s why he called us,I was fat that make me impossible to play Athletics I asked him "why me" he answered with self-confidence" you would be a substitute and it would be a favor for me" I agreed for just traveling to Fayoum,We received clothes but none of them like my size, the largest size was large and my size was XXL, I took any trouser with any t-shirt as I won't play but what happened was far of my imagination.
I received a fake ID card of someone, when I entered security man looked to ID , he seemed surprised, he looked again and said " enter enter".
Few minutes later one of competition organizer came to said "be ready"
I told him I am a substitution I won't play, he said me "no substitution here all would play" I weird narrow clothes that seemed to be cut and began a game
First game was run 50 meters
Referee said to us "I would whistle and make flag up to other referee would begin stopwatch"
few seconds later he whistled and runners ran except me he wondered of staying
I told him that he forgot flag up, he shouted me " you kidding me?! Move move"
And when I arrived the other referee said with smile "we have a new world record there, You are the slowest runner I had seen"
Second game was run 800 meters.
We were 20 runners when began I ran very fast and I was the first after 40 meters I can't breathe well I decreased speed all runners exceeded me ,I walked that I can't run,the distance between me and previous runner can't see from my eyes after all arrived referee was a crazy as one is lost he asked them if they were 20 or 19 after 15 mines I showed again
There was a girl ran to me for helping me to arrive and when I arrived she said"you okay? need water? "
I said"I need Jose cause I feel Low blood pressure,she let me and left
"OK water I am sorry" I said
It's time to push up these words fall down on my ears like a thunderbolt
I didn't practice this game and I didn't expect playing it in my life
I started to play after 5 minutes of referee explanation
Playing was so difficult, my arms were tiered from up and down,after that pains man said"no no your back wasn't straight"I looked at him with more rage with artificial smile
After that I felt like a paralyzed,I stayed in my home 3 days to improve again
