All depends on your pace, Eddie Izzard was setting off at 10.30 AM and finishing at around 6.30 PM so most of it was at walking pace... no problem. I did a 2.44 Marathon and was knackered for a month afterwards whereas cycling to Brighton & back from London is no big deal at a steady pace. I would say a 3 hour Marathon was the equivalent to a 5.20 IronMan bike of 112 miles. Jim
