2010 Indianapolis motorcycle Grand Prix
The 2010 Indianapolis Grand Prix was the eleventh round of the 2010 Grand Prix motorcycle racing season. It took place on the weekend of August 27–29, 2010 at the Indianapolis Motor Speedway.
During the second of two United States Grand Prix Racer Union 250cc (age 12-18) races during the race meet on August 29, 13-year-old Peter Lenz was killed during the warmup lap before the start. It was the first competitor fatality at the Speedway during a race since 1973.
An eight-motorcycle crash in the Snake Pit at the start (#34 R. Hayden, #29 Iannone, #2 Talmasci, #52 Pesek, #61 Ivanov, #3 Corsi, #48 Tomizawa, #56 Ranseder) led to a red flag and two retirements (Tomizawa and Ranseder) immediately. It was later restarted, with the distance shortened to 17 laps.
Marc Márquez was given a 20-second penalty after the race for cutting the track.
