Genetics, training, motivation and an ability to tolerate oxygen deprevation
Some people have muscles and nerves which work faster than others and are made for fast sprints. They seem more efficient at using their food as energy so are able to train for longer and then run faster than others.

I think it comes down to a lot of things: like your body type, your diet, your general fittness and level of activity. Stamina comes into it too. And training.
I’ve been training for the 10K run I did yesterday. I’ve never really been into a sport and I’ve never done a run before, so my overall fitness wasn’t good. On my first training session I could only run for about 10 mins before being completely out of breath! I heard that most people can do a 5K in 30 mins so I decided to aim for that. After 3 weeks of training 3 times a week, I managed to do a 5K in 24 mins.
When I did the full 10K run yesterday, the first 3K was uphill which I found tough as I hadn’t tried that in training. But you just have to push through it. I think that a lot of distance running comes down to stamina and motivation. It feels like you can’t do it and that you are doing to have to stop, but you just have to keep doing!

Thanks Sarah and Tim for a good summary.
For body type, this can apply to lots of different things, from your circulation, to height (length of your legs), muscle and body fat.

Genetics plays a big part: many of the top sprinters in the world are of West African ancestry whereas many of the top marathon runners in the world are of East African ancestry!
