Start your engines and head to Lake Marble Falls, whose calm, warm waters will once again transform into a veritable racetrack for the LakeFest Drag Boat Races, August 11-13. More than a hundred boats will reach speeds of more than 260 mph as they race across this reservoir on a bend in the Colorado River for the 26th consecutive year. As racers take to their boats each day from 9 a.m. to 3 p.m., the banks of the lake turn into a lake party, with a special treat for spectators beginning after dusk: a free concert at the Johnson Park Amphitheater. While there, fans can see the boats up close, take photos with their favorites, and meet the drivers. On Sunday, the winners drive away with more than $100,000 in prizes.
