Bruce Jenner -- High Speed Lambo Race -- I Sucked, But At Least I Didn't Lose!

Bruce Jenner got behind the wheel of a $300K Lamborghini this weekend -- and burned rubber during a real life race on a Virginia track ... and while he didn't win, he didn't lose either!

Bruce and his son Brandon teamed up as tag-team drivers for the Lamborghini Super Trofeo at the Virginia International Raceway, taking on 13 other cars at breakneck speeds.

The Jenners competed in two races -- one on Friday, one on Saturday -- and finished with a respectable 10th and 7th place ... not bad, considering they're not exactly seasoned pros.

We're told the Jenners have become obsessed with the sport -- and plan to get back on the track later this month for another race at the Autoclub Speedway in Fontana.

A wise man once said, "If you ain't first, you're last." Then again, that wise man also got into a car with a live cougar ... so take his advice with a grain of salt.
