It was a fight between physical exhaustion and mental strength.
During the 26.2-mile long London marathon held on April 23, something unexpected happened. Runner Matthew Rees stopped running to support fellow contestant David Wyeth after he nearly collapsed just metres away from the end line.
David Wyeth's legs started to clamp. Rolling along The Mall, head dropping, it seemed like he would not finish the race. But what happened next has gone viral and is a proof that humanity is not only the best virtue but also triumphs all kinds of success.
Read the whole story below.
"I saw David, his legs had completely collapsed beneath him. I went over, and he said 'I've got to finish' and I said 'you will' and I helped him up."
Mathew's effort reminds of a fatigued Jonny Brownlee, who was cheered up at the end line by his brother Alistair in the Triathlon World Series in Mexico last year.
Jonny needed the treatment, but he later tweeted he was OK, with a picture of himself resting in a clinic bed on a drip.
"I wish the flipping idiot had paced it right and crossed the finish line first. You have to race the conditions. I was comfortable in third. I ran the conditions, I took the water on, made myself cold, and I was alright."
"At the end of marathon, runners usually have given so much physically that their energy levels are completely depleted - the term is hitting the wall."
He added, "What that means is your body is struggling to find enough physical energy to move forward, the body is trying to tell you to stop."
"For every-day runners, it is about learning to understand how your body responds. We would call it listening to your body," Martin said.
Training for a marathon, pacing yourself and the correct fuel and hydration is important in avoiding the wall and the so-called jelly legs," he added.
"Your mind is telling you to keep going, and your body is getting to the point where it says NO, your legs do turn to jelly - it is horrific. It is like being a horrible version of drunk. It is sheer exhaustion," Tim remarked.
Navin-Jones, who has run five marathons said it 's hard to know how to pace a marathon for those who have not done it before. "A common mistake is runners starting a race too fast", he said.
"So what you want to try and do is keep your carbohydrate stores topped up during the race to prevent you from predominantly having to use fat as a fuel. When we use fat as a fuel, we have to go slower because as a process of burning energy it is a more complex and a slower system, so we can only support more time-consuming exercise."
"It is down to hydration. You will come to a point when you are tired. Have you overexerted yourself? Have you had enough calories? Enough carbs? The more you train, the higher your fitness levels become, so you can sustain it (running) for longer. If you understand what your body wants, just give it what it wants."
All said and done, what is important is this. Moments like this defines humanity and becomes an inspiration for coming generations.
