The Asphalt Jungle
FRI 8/8
If the wilderness is just too damn easy, why not tackle the urban landscape? Ironpersons will do just that at this weekend's Quest Houston Urban Adventure Race. With mountain bikes, scooters, canoes and feet, three-person teams will try to conquer the late-summer swelter. The contest will take them all around the city, from downtown to Reliant Park, AstroWorld, the Galleria and beyond. There are actually two levels of this exhausting endeavor. The five-hour race is "Quest Basic"; the 24-hour race is "Quest Extreme." The insanity begins at 7 p.m. Friday, August 8. Minute Maid Park, 501 Crawford, just before the Astros game. To re-Quest information, just call 512-863-3715 or visit terrafirmapromo. -- Eric Norvell
