Best of luck to the pair of them but it has been done.
Maybe its the the fact they are trying to do it in 2 days!!
We were one of the sponsors for "Operation Rigid Lion".
That was the Amry doing it in the Humber 6.2m, to raise money for St Dunstan's.
They were most deff petrol engines.
But all power to their elbows and padding to their bums.
They are going to have to push it to do it in 2 days
Rough guess approx 40mph for 48hrs non stop.
That is going to really hurt!!!
