Are you wearing trainers?

It's oft said folk in fashion stay skinny with bucket loads of cocaine and very little food. And though there are plenty for whom I know that's true, there are some who seem to believe in exercise too. Exercise, I hear you say? Like in trainers? Yep, really. Recently it seems more and more fashionistas are swapping their Alaia heels for Adidas trainers. Vogue.co.uk editor Dolly Jones did the London marathon this year, raising £15,982.48 for charidee with donations from designers Roksanda Illncic and Antonio Berardi as well as the British Fashion Council's Hilary Riva. Grazia's Editor-in-Chief Jane Bruton just wrote about her experiences, which saw Anya Hindmarch and Paul Smith digging deep into their pockets to help her raise £6,551. And I've just discovered the amazingly groomed and gorgeous PR for Louis Vuitton, Marsha, completed two out of the seriously hardcore Three Peaks challenge - where you climb Snowdon, Ben Nevis and Scafell Pike in 24 hours. Who knew sweaty wristbands and lycra were so fashionable?
