i suppose you could walk it 3 mph for 10 hours a day
but I don't understand what they are doing about injuries, even minor little aches and pains, blisters or whatever that will get worse and worse if he keeps on running
I made a comment on the other thread about this. I just can't believe it the way the challenge is written. It's such a massive attempt without any training of note. I think he had blisters after a couple of days.
You could walk for ten hours at 3 miles an hour, but even that
is pretty tough!! Mentally and physically. From what it says he is running though isn't he?
