I managed to grab a word with a few famous faces at the start. Chris Evans was playing it exceptionally cool, while Judge Rob Rinder was casually talking of going sub-three hours. Sprinter Iwan Thomas was a ball of energy. It was rather bizarre to bump into MP Simon Danczuk, who's been suspended by the Labour party, along with his estranged wife Karen.
Already tempted to tuck away your trainers in time for 2017's resolution attempts? Then spare a thought for the thousands of people braving those dark January mornings - and even darker nights - as they prepare themselves for what is, for many, the ultimate running challenge: the London Marathon. I never thought I'd be one of them.
