This Sunday is the London Marathon, and even if you're not taking part, the event always serves as a bit of fitness inspiration to kickstart your training regime - whether it's currently non-existent or just in need of a bit of a boost. I'm personally viewing the marathon, along with the return of warmer weather as a turning point in my exercise schedule, and hope to mark the occasion with some fantastic new high-performance running shoes!

There are so many stylish and hi-tech trainers out there at the moment that I really don't know which to choose: there's Adidas' range with its innovative Boost technology and stylish collaboration with Stella McCartney; Nike's fantastic free run range with its uber bendy soles and so many more brands with exciting products on offer.

I've included all these and more in this selection of running shoes, starting from the most hi-tech and advanced for those really wanting to get competitive, to trainers inspired by high performance sportswear for those who just want to get a bit more energetic with a cool and casual shoe.
