TRIATHLETE twins had double cause for celebration after winning gold medals at a national event.

Super siblings Charlie and Olivia Lyne from Wemyss Bay both triumphed at the Scotland National Youth Triathlon Championships at Bellahouston Park in Glasgow.

The sporty seven-year-olds each tackled a 50-metre swim, a 1.4 kilometres bike ride and a 600 metre run.

Charlie completed the course in nine minutes and 33 seconds with his sister finishing in nine minutes and 45 seconds.

Charlie, said: "I'm really pleased I came first because the boys who came second and third have beaten me before in the past two aquathlons.

"I really like swimming, cycling and running.

"I love to cycle - my dad takes me up the long way to Largs which is really tough as there are really big hills."

Olivia added: "It feels really good to win a gold medal."

The pair's parents Jane and Stephen say they are very proud of their achievements.

Jane said: "They work really hard."

The twins, who are going in to P4 at Wemyss Bay Primary just after the summer, train with Fusion Triathlon club in Glasgow and swim with Inverclyde Amateur Swimming Club.

Jane, 47, says Charlie and Olivia were inspired to take up the sport by their older sister Jennifer, 18.

She added: "Their big sister trained with Fusion and did quite well but she's 18 now and is away to Camp America.

"Charlie and Olivia used to get dragged along to watch triathlons, now they're old enough to compete which is fantastic for them.

"They are very competitive against each other - when you see them training in the pool on a Sunday morning, they are both desperate to get past each other."

The twins are keen to thank all their coaches, especially Kerry and John.

Their team-mate Ella Morrison, eight, from Kilmacolm, claimed a silver medal at the same event.

The youngsters are now looking forward to a week-long summer camp with their triathlon club and plan to do more races come autumn.
