Lisa Carrington, gold medal in K1 200m

Sarah finished the medal race a bike length behind Colombian gold medallist Mariana Pajon.

Sarah's friend and training partner, Dutchwoman Laura Smulders, won bronze.

Sarah's road to London has been a struggle to come back to form after she crashed three months ago in Norway and dislocated her shoulder, threatening her Olympic dream.

Lisa Carrington says headwinds at the kayaking course played to her strengths. The 53kg paddler, is up to 20kg lighter than some of her rivals. She was able to use her power-to-weight ratio to good effect, and she could count on her endurance.

Her win was watched by about 150 people including former coaches, school friends and grandparents, who watched her race on a big screen at the Ohope Surf Club.
