My OP is incorrect in one regard, there is an ebike in there but they don't mention it as such. Martyn Ashton's modified bike is an ebike of course, as he's a parapalegic. If you go to the 57th minute you can catch a bit of the action.
Also, the look on his face when riding the course at Ft. William speaks volumes about the enabling technology that has us here on this site. Ebikes open up whole new opportunities for a lot of us that would struggle otherwise.
