My go to local hike starts at 450ft above sea level and goes to 1150ft sea level. However it has many ups and downs so the total ascent is ~1250ft. To the top of the mount/hill and back to the trailhead is roughly 4.5 miles. So to "Everest" on this hike using total ascent numbers I would need to do this hike 23 times, which would cover about 105 miles. Seems like I would need to take up extreme trail running to accomplish this in one go. Interesting idea but probably not for me.
