Born to run: genetic test can reveal those best able to run marathons“[T]o run a marathon in a good time requires the right combination of genes and that nearly a fifth of the population lack this special mix. For runners with the right genes, it means their bodies can quickly adapt to carry large amounts of oxygen to their muscles, allowing them to run faster and for longer. Those who lack these genes, however, will never improve, no matter how much they train, and their performance may even get worse the harder they push themselves.”
