DORNEY LAKE, ENGLAND ? If former University of Wisconsin All-American rower Kristin Hedstrom is going to make it to the Olympic medal podium, she?s going to have to do it the hard way. In the heats of the women?s lightweight double sculls on Sunday, Hedstrom and her partner, Julie Nichols, finished third among six boats. Only the top two crews in each heat advance directly to Thursday?s semifinals.
