Katie Byers produced her best outdoor performance of the year when it counted to set a new British Junior Record on day two of the England Athletics Aviva U20 & U23 World Trials and Championships. Online results from Bedford are available here, and full downloadable results here.  You can also now watch every event on EATV.

The weekend saw 11 Championship Bests and plenty more athletes all but book their place on the flight to Barcelona for the IAAF World Junior Championships with some superlative performances, but none more so than Byers' 4.36m effort which added 16cm to her outdoor best and 1cm to the previous British Junior Record held by Holly Bleasdale.

Another outstanding performer over the course of the weekend was Sophie Papps who won two close battles with Dina Asher-Smith (who ran 11.54 to go fourth on the UK U17 All Time lists in the 100m heats) to win the 100m and 200m in 11.47 and 23.48.

Sophie said after her 100m victory: "It was a really high quality race and we all knew it was going to be hard with a lot of girls running PBs to get into the final, and in the final, so it was really exciting to be a part of it. I'm happy that I won it, but I'm really happy for the girls because everyone did so well."

The 100m finals were also packed with quality and didn't lack excitment either. In a much anticipated U20 men's 100m final, David Bolarinwa had to fight off strong competition from Chijindu Ujah and Joshua Street to win in 10.40.

Street, strong over a range of distances up to 400m, ran a fantastic race to win the 200m final on Sunday, slicing more than three tenths off his best to dip under 21 seconds for the first time, as well as the World Junior qualifying mark, with 20.90.

Both Bolarinwa and Adam Gemili were in action in the 200m heats, but had to pull out of the final, with Gemili producing a lifetime best over 200m with 20.60 in a much-anticipated outing following his recent breakthrough performances in the 100m.

The U20 men's 110m hurdles saw James Gladman set a new Championship Best of 13.50 to win by almost half a second in a new lifetime best and well under the time for the World Juniors.

In the women's equivalent, Commonwealth Youth Champion Yasmin Miller took victory in a windy 13.74 after clocking a new best of 13.77 in the heats, edging closer to the World Junior mark of 13.70.

The U23 women's race saw Blackheath's Serita Solomon edge Ashley Helsby with both setting big PBs to go to the top of the U23 rankings with 13.28 and 13.29 respectively, on a weekend when Helsby's coach Malcolm Arnold was awarded an OBE in the Queen's Birthday Honours.

The throws produced some of the best quality performances of the weekend. Great Yarmouth's Sophie McKinna did all she could to book her place on the flight to the IAAF World Junior Championships in Barcelona. With the qualifying mark already in the bag, McKinna threw over 16 metres for the first time ever to win the U20 women's shot, setting a new Championship Best of 16.16m in the process.

Sophie said: "It's absolutely fantastic to produce a PB and something like that here today, now was really the time to do it."

Shaunagh Brown also produced a Championship Best in the U23 women's shot with 16.31m for a clear win, while Zane Duquemin retained the title he won in 2011, also with a Championship Best and his furthest ever throw of 18.48m.

Happy with his performance, Zane said: "I won it last year as well so I defended my title, but I was disappointed with the distance last year, so I'm pleased to get a PB."

London 2012 discus hopeful Lawrence Okoye, came back to the scene of his fantastic breakthrough in 2010 this time as an U23 ranked number four in the world. The Croydon man didn't disappoint, battling against strong winds to record a winning distance of 63.66m - a new Championship Best.

Kingston Upon Hull had a great weekend, winning two gold medals in the hammer competitions with Abbi Carter retaining the U20 women's hammer title she won in 2011 with 59.21m and Peter Smith throwing a Championship Best of 67.01 to win the U23 men's hammer.

There was another Championship Best in the U23 men's javelin thanks to a 75.93m effort from Joe Dunderdale, while Matti Mortimore went to the top of the UK U20 rankings and bettered the World Junior mark with 70.54m. Kai Jones became one of the youngest ever champions at just 15 years of age, winning the U20 men's shot with 16.96m.

In the distance events, Scotland's Emily Stewart surprised herself with a fine display of steeplechasing to win the U23 women's race in 10:02.63 at just her second attempt at the event. It was a new Championship Best and took her to third on the U23 UK All Time list.

There was some excitement in the U23 men's race as Ben Nagy took a tumble over the water jump, only to recover and go on to record a fine victory to add the national U23 title to the BUCS one he won at the Olympic Stadium last month.

Jonny Hay was an emotional winner of the U23 men's 1500m. Bravely taking it out from the gun, Hay led for the entire race and showed speed and strength to power away down the home straight to win. Sixteen-year-old Sean Molloy won a competitive U20 men's 800m in 1:52.42, closing with a 54-second lap.

Jessica Judd won yet another national title by stretching out on the final lap to win the U20 women's 1500m in 4:29.14, in a race which saw Spenborough's Jenny Walsh - the senior champion and only other athlete with the World Junior qualifying mark - forced to sit out with a cold.

There was plenty of excitement in the jumps. Laura Samuel produced a huge Championship Best and PB of 13.75m to win the U23 women's triple jump, and part-bobsleigher Jazmin Sawyer was grateful for a just legal wind of +1.9 m/s which meant that her winning effort of 6.42m was a qualifying mark for Barcelona.

Well done to all the athletes who made it such an action-packed weekend and a big thank you to the coaches and to the officials without whom such events could never take place.
