Another weekend in Austin, another huge, festive, traffic-snarling event. But those who enjoy moving their bodies will rejoice at the news that the 28th annual Livestrong Challenge is coming to town this Sunday. Cyclists may choose from 20-, 45-, 65- or 100-mile routes while runners and walkers will be challenged by timed 5K or 10K courses around Lady Bird Lake. All routes wind up at Auditorium Shores, where participants are welcome to partake of festivities, enjoy food and drink, and snag their very own event T-shirt.
