After a three-week mid-season break the 2010 MotoGP World Championship returns to action with the Cardion ab Grand Prix this weekend, round ten on the calendar.

Refreshed and ready to take on the second half of the 2010 season the MotoGP riders and teams are back in action this weekend at Brno for the Cardion ab Grand Prix Czech Republic, where the chase to catch Championship leader Jorge Lorenzo recommences.

After nine of the 18 rounds of the season the Fiat Yamaha rider is 72 points clear at the top of the standings, thanks to his superb form of having taken six wins and three second places so far. Another top-two finish would make Lorenzo only the third rider in GP racing’s 62-year history to place either first or second in the opening ten races of a season, the others being Giacomo Agostini and Mick Doohan. To maintain his fantastic form Lorenzo will need to win at a circuit he has not yet triumphed at in the premier class, after crashing last year when battling team-mate Valentino Rossi for the race lead. He does have a fine record in the smaller classes there however.

Dani Pedrosa is the closest to Lorenzo in the standings at present and the Repsol Honda rider has a point to prove following his crash at Laguna Seca in the previous round. The Spaniard enjoyed a consistent run leading up to the summer interval and was leading the race in the U.S. when he fell, and has twice finished on the podium at Brno including second place last year – his best premier class Brno result.

In third place at 23 points off his team-mate is Andrea Dovizioso, who is eager to rediscover his early-season podium form, whilst the resurgent Casey Stoner (Ducati Team) is hot on the Italian’s tail. Stoner did not race at Brno last season but has tasted victory there (in 2007), something he is still yet to do in 2010 but a result that appears to be moving ever closer after four successive podium finishes in the last four rounds.

Brno has been a very fruitful hunting ground for Valentino Rossi who has five premier class wins there (it was also the site of his first 125cc win), and the Italian has been victorious at the Czech track for the last two years. A podium last time out at Laguna in only his second race back from injury moved him back up to fifth, where he sits a single point ahead of Nicky Hayden (Ducati Team). Another American rider, Ben Spies (Monster Yamaha Tech 3) is also closing in on the top five and Brno offers a familiar circuit for the rookie, who has previously ridden there in WSBK.

Set to make an extremely speedy and very welcome return to action from his broken leg is Randy de Puniet (LCR Honda). Pending medical clearance the Frenchman intends to ride again just four weeks after his crash at Sachsenring – last year he rode to tenth place at Brno having broken his ankle just three weeks before the race.

San Carlo Honda Gresini pair Marco Melandri and Marco Simoncelli are closely matched in ninth and tenth in the standings, whilst Colin Edwards (Monster Yamaha Tech 3) will follow up his best result of 2010 so far with an attempt to place higher than seventh. Héctor Barberá (Páginas Amarillas Aspar), Rizla Suzuki pair Loris Capirossi and Álvaro Bautista, and Pramac racing duo Mika Kallio and Aleix Espargaró will all aim for improvements, and Alex de Angelis (Interwetten Honda MotoGP Team) is set to continue in place of the injured Hiroshi Aoyama.

The first MotoGP practice session of the Cardion ab Grand Prix Czech Republic starts at 1.55pm local time on Friday.
