UK record holders lead AVIVA GB&NI Juniors for Loughborough International

World junior champion and UK junior 100m record holder Jodie Williams (coach: Mike McFarlane) leads a strong Aviva Great Britain and Northern Ireland junior team at this weekend's Loughborough International, the first major fixture of the McCain Challenge Series (Sunday 22 May) and an early indicator of form ahead of this summer's European Junior Championships.

17-year-old double World Youth Champion Williams, who finished fourth in the European Indoor Championships in May, reduced Kathy Cook's UK under-20 100m best to 11.24 12 months ago and steps up officially into the junior age group as part of the 4 x 100m relay squad. She will also guest in the invitational 300m.

Jessica Judd (coach: Jeremy Freedman), the current world leader (under-18) over 800m and 3000m, has been in outstanding form this year and clocked a UK under-17 best - albeit in a mixed race - over 3000m (9:08.5) in April. The UK Inter Counties and Aviva Schools International Cross Country champion contests the 1500m on Sunday.

In the shot putt, Sophie McKinna (coach: Geoff Capes), fifth in the 2010 Youth Olympic Games and senior bronze medallist indoors at the Aviva European Trials and UK Championships, is now ranked second in the world (under-18) after a recent 15.71m PB at Kings Lynn and will want to build on that mark this weekend.

Amongst those also competing in the Loughborough meeting on Sunday are Abi Oyepitan (coach: Tony Lester) in the 200m, Perri Shakes Drayton (coach: Chris Zah) in the 400m, Hatti Dean (coach: Bud Baldaro) in the 3000m, Louise Hazel (coach: Aston Moore) in the 100mH and Eden Francis (coach: Glenys Morton) in the shot putt and discus, all for England. Jessica Ennis (coach: Toni Minichiello) will guest.

Kevin Tyler, UKA's Strategic Head of Coaching and Development and Aviva GB & NI Team Leader for the European Junior Championships in Estonia in July, said: "Loughborough is a great chance for our juniors to compete against senior counterparts in a quality match early in the season. As in past seasons this event marks the start of an important summer schedule as they work towards qualification for the European Junior Championships."

Paul Aldridge, UKA Event Manager, said: "The 2011 McCain UK Challenge encompasses 47 events, and offers athletes four months of intense quality competition across the Home Countries.

"As previously, we'll be using our unique rankings so that every competing athlete can register their top four performances and strive for a place at the Final.

"There's a 40k prize fund available across the season and athletes can once again target their summer competitions aiming to rise to the challenge."
