A summer’s day in McLaren Vale is normally a chance to relax. Not so for riders, who face a tough afternoon while touring the district’s most scenic roads. The formidable Willunga Hill returns – this time with a new twist. First comes a descent of its slopes, followed by a loop that will take cyclists out to the Aldinga coast, past celebrated wineries and up the steep Wickham Hill. Two ascents of Willunga Hill are set to determine the stage winner, and there’s plenty of potential for a breakaway to call the shots.
