Going by the astonishing tall tales he spread about himself, I would be surprised if it wasn't.

The following video is a psychologist's take, well, a YouTube psychologist's take on some of his many implausible, superhuman and grandiose claims that include:

Running 30 marathons in 35 days, notably running the final nine marathons with a fracture.

To have completed 600 miles of running in just six days.

Raised over £5.5 million ($7.4 million) for charity.

(Time) travelling to Brazil on a relief mission where he personally installed water pumps for local populations as part of a program that shut down before he was born.

cool guess! idk about jason arday, but that dude in the first link is strange and off putting. too much stink face, and the way he frames the subject with the blurry photos and loony screenshots feels like bullying.
