IF Paralympic medals were awarded to mums and dads then Moira and Peter Clegg would have topped the podium last night.

First they watched son James win a surprise 100 metres butterfly swimming bronze, then, after an excited and breathless dash across Olympic Park, they just made it in time to see daughter Libby win 100 metres silver at the Olympic Stadium.

It was a famous double for the Scottish siblings from Newcastleton, and then the proud parents repeated the feat in a bid to catch both medal ceremonies. At the end of the night it was difficult to tell who was more exhausted.

Clegg found out her brother had finished third just moments before walking on to the track. Expectations were high after winning gold at last year's World Championships, but she'd seen the world record re-written three times in two days with China's Guohua Zhou the pre-race favourite.

Zhou did not improve the 11.91 second mark she set in the heats but still ran the second quickest mark of all-time in the T12 classification, while Clegg settled for a new 12.13sec European record and the scalp of defending champion Oxana Boturchuk.

"I found out about James in the call-up room," said Libby Clegg. "Half of me didn't want to know before my race but curiosity got the better of me and I asked an official to look it up on the internet.

"It was a big boost for me because he was only really meant to be here for the experience. I'm so proud of him, he's only a baby. I had to get a medal – I couldn't have my little brother beating me."

But Clegg, who will compete again in the 200m later this week and was guided to victory by Mikhail Huggins, admitted there was a tinge of disappointment after arriving with hopes of gold.

"I'm slightly disappointed, but I couldn't do any more than I did," she said. "It was a really tough race and the standard was really high.

"We've run three lifetime bests in two days and that shows how tough it's getting. Mikhail kept me calm, told me to stay relaxed, keep pushing and then dip.

"Bring on next year now, I can't wait. The World Championships are in Lyon and hopefully I will have a full winter's training."

Meanwhile, across Olympic Park her brother was struggling to comprehend his podium performance.

As expected, Belarus world record-holder Roman Makarau won gold by a clear margin with Russia's Sergey Punko and Clegg chasing him home. He clocked one minute exactly, slightly slower than his British record time in qualifying.

"I wasn't meant to be on the podium, it's my first Games and I didn't really have any expectations," he said.

"I'm so happy with my swim, I came here wanting a personal best but to leave with a medal is really beyond my wildest dreams.

"Libby has been a brilliant help for my first Games. She's always there supporting me and telling me what to expect.

"She said the crowd would be amazing and she was right, I've never felt such an atmosphere or support. She told me to embrace the crowd and use it to my advantage and that's what I did."

Elsewhere, Aberdeen's Neil Fachie may have lost out on a second London 2012 cycle title to his former co-world record holder but he insists any re-union with fellow Scot Craig MacLean would be temporary, claiming he wants to pursue double gold with Barney Storey at Rio 2016.

Fachie and pilot Storey, 28, got the better of MacLean – and his partner Anthony Kappes – by default in the final after they suffered a technical failure to capture his first Paralympic gold medal in the kilo on Saturday.

But 24 hours later, when the two British pairings locked horns in the sprint final, it was Kappes and MacLean who prevailed.

When the dust settles on London 2012, thoughts will turn to the Glasgow 2014 Commonwealth Games and both Anglo-Scottish pairings will almost certainly revert back to their previous partners.

But Fachie was adamant that any attempts to upgrade his London 2012 gold and silver to double gold in Rio will be done with Storey, a three-time Paralympic champion.

"Barney and I have ridden very well here together. I'm sure there's room for improvement, but if he wants to ride to Rio then I'd love to ride with him and go and aim for two golds – I'd happily ride with him any day," said Fachie.

"It was great, to get both the GB teams in the final was the goal and on a personal level, to guarantee gold and silver is fantastic – that was always the goal, to get both pairs into the final and fight it out between us."
