Three times further than you’ve ever run in your life. You’re at the final mile of your first ever marathon, and your legs feel like rubber and your heart feels like it’s going to explode out of your chest.

It takes everything within you not to collapse. But despite your best efforts, your knees buckle and you fall to the ground.
If there was any water left in your body you might cry.
