Mark's observed velocity during the competition is about 60 ft/sec (anyone that has watched Mark as MC during a match can attest to this). At this velocity, it should take Mark about 60 hours to run from Atlanta to San Jose, pulling a trailer full of Red Bull (which he is consuming as he goes). With 1 HP = 550 ft-lb/sec, that would mean he is putting out about 2831 horsepower during his little jog. Yeah, that seems about right.
Anyone else see the conceptual error here?

Force required to move an object is only equal to the object's weight if it's going up. Power to move a trailer carrying a 13 ton payload at 60 ft/sec (about 40 mph) roughly horizontally is certainly much less that 2831 HP.

I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.
