People even call me Christine, know me as Christine’s sister, and most don’t even know my name, it’s annoying,” Victoria said on the eve of the inaugural Youth Olympic Games in Singapore, where she will be one of 39 British athletes competing in 16 sports.

“We are completely different people, she is more reserved and quiet, I am loud and messy, she is like a kind of mum to me, kind of bossy.” But Victoria, at 17, acknowledges that big sister and former world champion Christine is an inspiration, even though “I don’t think I realise what she has done is quite big, because she is just my sister”.

Victoria has picked the 400 metres, like her sister – slashing her personal best from 59.35sec to 54.17sec over the past year, though she is some way off Christine’s PB of 49.61sec. She dreams of both of them being in the London 2012 Olympic Games final. But perhaps more realistically she has her eye on a London 2012 relay berth. “I do want to be there,” she said, especially as the Olympic stadium soars nearby her Stratford house. “It is such a big motivation and everyone feels they have a right to be there.”

Competing in Singapore, and having such luminaries as Amy Williams, gold medallist in the skeleton bob at the Winter Olympics, as part of the official delegation is a big motivational boost too. “It will give me a taste at the big time, it is not just racing in the UK.” For Williams the week in Singapore amid 3,500 athletes will give her a chance to revisit the excitement of the youngsters “and remind yourself why you do it”.
