True, but that doesn't make it easy to do.
running isn't easy NECESSARILY, but outside (or I guess physiological and developmental factors) make it easy, sometimes.
For me as a 7th grader, rising to the top at my school and conference was easy. I had been lapped and mogged in middle school basketball court mile runs for National Fitness Tests by people who would go on to become lazy sprinters running 12.8 as juniors and seniors.
But suddenly, even though I played battlefront, Zelda OOT, and RuneScape a lot, I quickly pulled up with a 5:40 winter of 7th grade, and a 5:19 for the spring.
I never reproduced that rate of success again in overall distance running, however, I did have a brief comeback in Jr year wherein I rose from a year+ of injuries and finally shaved off 20 seconds to run a 4:46, all in the span of 3 months.
Then, senior year was stagnant - until I began lifting toward the end of the year.
then, I did a time trial 300m and saw the watch tick past 36.9 when I went through the line. This was a month and a half after states, 2+ months post-taper, just lifting. All of a sudden, the environment was right to produce explosive times.
All of that was relatively easy. But summitting Everest? Heck no. You'd dump your britches if you wound up a mountain on a base camp, as would most reasonable people. That's coming from me, someone who climbed Mount Fiji. Fiji was hard.
My partner and I were passed by many dedicated and experienced old folk on our way up.
