An amazing effort by Paul, he was down there religiously every other day or so for weeks, good dedication! Boy Band/Stamina Band next, although he's probably sick of the sight of the place by now.
I've no doubt that Ben could have done this having seen how strong he looked on the PUTP section in the video. I think one reasons that he never did it was that it was viewed simply as a training challenge back then, not as an end in its self. I think if he thought he would have got a V14 tick for a couple more sessions on it he would have done so.
