Here they are after about 400 metres.
And at the 2.5 mile mark, struggling a bit and going up hill, but still smiling.
They did it in 2 hours and 42 minutes. A good time for Carl, who has only gone about 8 miles in training up until now. Carl thinks he was 1198th.
Well done, boys.
(And not an ambulance in sight!)
Post Script: Apparently there were less than 1200 runners. Carls official position was 1042, more than 2 people finished behind him, and several did not finish at all!
