Bryony Shaw will race for a repeat of her Olympic bronze medal when the RS-X windsurfing competition at Weymouth reaches its climax with the medal race on Tuesday.

The Tunbridge Wells-based star recorded a win and a fifth-placed finish in Sunday afternoon's races to keep alive her hopes of a repeat of her medal-winning performance in Beijing four years ago.

The 29-year-old (pictured) narrowed the gap on the medal places with her win in the first race of the day, and the ninth race of the competition overall.

She pipped Brazilian Patricia Freitas to the line by just five seconds to take first, but was then 1.55mins adrift of the winner in race 10 to claim fifth.

In RS-X the higher you finish the fewer points you get. So the winner gets one, the second two, 10th gets 10 and so on.

Shaw finished seventh in the standings, with the top-10 going through to Tuesday's medal race, which gets under way at 2pm.

In the medal race the points are doubled, so the winner receives two, second four, 10th 20, etc.

Shaw needs to make up 12 points on the third-placed Finnish competitor Tuuli Petaja and 15 points on Israeli Lee-El Korsiz in silver position for her to claim a second successive Olympic medal.

Spaniard Marina Alabau Neira has already all-but sewn up the gold.

Shaw effectively needs to get into the top-two with the other two finishing in the bottom-two if she is to claim silver.
