Caught your breath from last week’s action-packed schedule of fantastic racing yet? Well, prepare yourself for this weekend because we’re giving you even more motorsport goodness.Following on from the world-famous 12 Hours of Sebring, it’s time for round three of the United SportsCar Championship – the Sportscar Showcase at Long Beach.

But local lad Pruett will have to focus on the race rather than the scenery if he wants to make it two in a row at the former F1 circuit. You can follow the full race this weekend (and admire the views) courtesy of your favourite television channel as we bring you live coverage from the best sportscar series Stateside.We’re also showing some two-wheeled action from the pinnacle of motocross racing – the FIM MXGP Championship.
