It is another light weekend for international racing, but one race makes up for it - the return of the FIA World Endurance Championship. The FIA WEC has not had a race since the 24 Hours of Le Mans 10 weeks ago, and it is great to finally see the sports cars back on track. 

In other sports car racing news, the American Le Mans Series and IndyCar Series are splitting the weekend at the Baltimore road course. The ALMS cars will race on Saturday, and the IndyCar Series takes to the streets on Sunday. 

If you are into motorcycle racing, there is the MotoGP British Grand Prix from Silverstone.
