The Vancouver Courthouse Criterium features nine racing divisions, including two for women. Portland’s Amy Campbell, in white, won the Senior Women’s category. Anna Christenson, in black, also from Portland, finished third. A criterium is a short road race on a circuit — usually city streets — closed to traffic. A mass start, high-speed cornering and sprinting make the criterium exciting for participants and spectators alike, say advocates of the sport.Alpenrose VelodromeCrit resultsThe whir and buzz of bicyclists hitting speeds of nearly 30 mph echoed in downtown Sunday as nearly 150 competitors challenged the 10-block Vancouver Courthouse Criterium.Experienced racer Heather VanValkenburg, 37, of Vancouver said the crit was not her best effort but noted, “My teammate, Amy Campbell (of Portland), won the race.”VanValkenburg, a sixth-grade teacher at Daybreak Middle School in Battle Ground, described the course with its eight turns.“It’s start, turn, you’re going, turn,” she said. “It’s a good course because it has character in it. … Having eight corners makes ita really technical course.” She competed in the Senior Women’s category on her Parlee Z5 bike, worth $5,000.There were nine racing categories and all racers flew by the courthouse at 12th and Franklin streets. City streets were closed and spectators watched from sidewalks, behind yellow police tape.
