It is a phenomenal ride. The guy may be a nutter, I've not watched his vids and don't really care, but that is amazing. Those roads are not hilly but riding for 22 hrs in a day takes some doing. A lot of people don't even manage that in the 24 hour TT!
Abdullah did a 480.8km day yesterday. 1,324m @ 21.3 km/h. 22 hours of headwind
