We have been learning to describe how we are feeling without telling the reader.
I kept on pushing myself I couldn’t handle any more. I kept my place in fifth. One more lap to go I could do it. But soon I had to breathe through my mouth; and it felt so dry like a parched desert my legs felt like jelly. I could see the finish line barely on the horizon fifty strides and then I could make it. But for some reason my legs suddenly felt like steel blocks but I didn’t stop I kept on pushing myself and then just then... yes I did it I crossed the finish line!
