downhill

As one carriage travels downhill, its weight lifts the other, allowing them to ascend and descend simultaneously, reducing the energy needed to transport them.

They are attached to opposite ends of a haulage cable meaning that as one travels downhill, its weight lifts the other, allowing them to ascend and descend simultaneously.

The 17-year-old from Cross Ash, Monmouthshire, had been racing downhill mountain bikes since he was eight, wanting to "go fast all the time", when he crashed before a race and pulverized one of his kidneys.

“We were cutting line and without warning, I heard someone yell, ‘TREE!’ and before I could react, I was hit in the back and rolled 5 to 10 feet downhill,” he wrote.

For many fans in attendance, the performance went downhill from there.
