You might not be quite as fast as Mario Kart 7 silver medallist James Newton, but if you fancy yourself as something of a Mario Kart 7 expert then you might want to head over to London's Westfield Stratford City next week to enter an official Nintendo Mario Kart time trial.

The event runs from 13th to 19th February at the Nintendo stand outside John Lewis, with other games on hand including:

Mario Kart 7
Super Mario 3D Land
Resident Evil Revelations (Over 16's only)
Tekken 3D Prime Edition (Over 16's only)
LEGO Harry Potter: Years 5-7
Nintendogs + Cats
PES 2012 3D
One Piece Unlimited Cruise SP

Also, buy a 3DS and software from the ground-floor GAME and you'll get a £10 eShop voucher, which isn't half bad.
