Crikey, I have recently entered the Milton Keynes Marathon, this will be the third time I've done this event. I didn't do it last year as I concentrated on cycling so I could compete in the Coast to Coast in a Day event. This was 150 miles on the bike over a very hilly terrain.
So, which do you think ought to be harder? Running a marathon or cycling 150 miles?
My gut reaction is a simple answer – running a marathon is easier, for me. And then the more I thought about it afterwards the more complex the comparison seemed.
