Pile Drivers

Sat 5/3
Hide your heaps -- Bigfoot's a-thundering this way. Be there! Be there! Be there! -- on Saturday, May 3, at 7 p.m. as Gravedigger, Bounty Hunter, Maximum Destruction, Scarlet Bandit, Monster Mutt and more roar into town for the Coors Monster Truck and Jet Car Jam at Firebird International Raceway. Giants rule the Earth as they race for best track time, spin dozens of doughnuts, and fly over track jumps and stacks of junk cars. What hath man wrought in 12,000 years of progress? Horsepower, baby. Don't try this in the minivan. Joining the behemoths, 6,000-horsepower jet cars light up the night. And when the jet tank takes aim at the finish line, don't blink -- the camouflaged all-terrain vehicle blasts by at 300 mph.

Gates open at 2 p.m. Kids: Party in the pits with a pit pass at 3:30 p.m. Get autographs, snap photos with your favorite drivers, and score giveaway posters and other free booty. Admission prices start at $24 for adults, and $32 for adult admission with a pit pass. Kids 12 and under get a free general admission ticket and pit pass with a paid adult.

Triple Threat

Only the strong survive Tempe's Multi-Sport Challenge

Sun 5/4 >It's been said that athletics are 10 percent physical and 90 percent mental. Whoever said so probably never had to master three grueling events within the confines of a single endeavor, but the point is still well taken. Strong physicality and solid mentality are a dream team in competition, a point made clear in an event called the triathlon.See sport's greatest multi-taskers swim, bike, run and otherwise make the rest of us feel inadequate at the Tempe Multi-Sport Challenge. It kicks off at 6 a.m. Sunday, May 4, at Tempe Town Lake, Mill Avenue and Rio Salado Parkway. This year's course combines a 1.5K swim, 40K bike ride and 10K run, with $3,000 cash up for grabs.

Admission is free. For details call 480-858-2059 or visit Sun 5/4

To Infiniti and Beyond

Faster than a roller coaster

While NASCAR events are considered, ahem, lowbrow by some who overestimate their own cultural panache, the Grand American Rolex Sports Car Series Phoenix 250 should appeal to the moto-snobs among us. On Friday, May 2, and Saturday, May 3, Vipers, Corvettes, Mustangs, Porsches, Acuras, Infinitis, Audis and more will burn rubber at Phoenix International Raceway, giving us a chance to see how our dream cars perform ... without the nuisance of speed limits and traffic cops.

During Friday night's United Auto 200, folks can watch the pretty machines race for a mere $10. Saturday evening brings the $20 main event: Two races -- the Grand-Am Cup Grand Sport Race and the Phoenix 250 -- feature not only the cars we already adore, but the new Daytona prototypes from major manufacturers as well. Purchase tickets through or 602-252-2227. - Brendan Joel Kelley
