i've walked at some point during every single one of my marathons and i still see it as a massive achievement that i completed them.
dont be too hard on yourself. why dont you continue with the training, trust in it and yourself a bit more, and for your first marathon just go out and enjoy it and dont worry about a time??
i would say
' i am afraid that i do not have the capacity to complete this today. Please can you see if there is anyone else available to assist otherwise I expect that I will be able to deal with this on if this would be acceptable'
or something like that! Delegate upwards!
I've just done Barcelona and feel fit and have friends running London - but I know it was a long shot!!
in the words of a minion - "oh poop"
.....does anyone know anywhere that has one available??!
