National U20 record-holders Molly Caudery and Jake Norris head the 40-strong British team for the IAAF World U20 Championships Tampere 2018 from 10-15 July.
Caudery twice broke the British U20 pole vault record in Mannheim last weekend, vaulting 4.45m and 4.53m on her way to victory, moving her to outright second place on the 2018 outdoor world junior list.
Norris, who is second on the 2018 world U20 list in the hammer, backed up his record-breaking 80.45m throw in Bedford at the England U20/U23 Championships with another 80m-plus throw in Mannheim, recording 80.28m to take victory.
Meanwhile, Commonwealth heptathlon bronze medallist Niamh Emerson will be looking to add another medal to her tally on the world stage.
Fellow Commonwealth Games star Alastair Chalmers set another 400m hurdles personal best at the weekend of 50.52 in his native Guernsey, while fellow 400m hurdler Alex Knibbs set a huge personal best of his own, clocking 50.57 in Mannheim.
