Duvernay and Peuch made a fast start to the tournament as they burnt up the front nine of the Jack Nicklaus signature course on day one. They fired five birdies and surged into the lead with an eagle from Duvernay at the par five eighth. Another eagle from the Evian Resort golfer and further brace of birdies earned them a three-point lead over English pair Kiran Matharu and Ellie Givens.
