Great Britain’s Amelia Coltman made the best of the track conditions to win women’s skeleton gold in the opening race of the World Cup series in Pyeongchang, South Korea.

The 28-year-old had never previously finished higher than fourth at a World Cup event, but after sitting in 15th following the first run she produced the second-fastest time in the second to win in an overall time of one minute 48.41 seconds.

She had trailed Austria’s Janine Flock – leader after the first heat – by 1.22 seconds, but as temperatures rose and the track slowed following Coltman’s second run, the early frontrunners were unable to match her time.

Flock finished second overall, 0.08secs behind, while Brazil’s Nicole Rocha Silveira, who was 13th after the first run, came through to claim a surprise bronze.

GB’s Freya Tarbit finished 0.02secs outside the medals in fourth, while team-mate Tabitha Stoecker fell from third place after the opening run to 18th.

The British team has three competitors – reigning World Cup champion Matt Weston, European Champion Marcus Wyatt and Craig Thompson – going in the men’s World Cup opener on Saturday, from 11:00 GMT.
