Everesting is seeing how fast you can go uphill the equivalent of Mount Everest, 29,029 feet (8,848 meters). To be official, the rules dictate it has to be one climb, up and down, over and over. The most I’ve ever climbed in one day is approximately 10,000 feet, a sad sack one-third Everester.

Now some unhinged cyclists have decided Everesting isn’t challenging enough. Real climbers now are “trenching”, as in descending the equivalent of the Mariana Trench, which requires climbing almost the same distance, 36,037 feet (10,984 meters) because again, it has to be on one climb, up and down, over and over.
