Dominating victories by Michael Norman in the 200m and Anna Cockrell in the 400m hurdles pushed the USA’s all-time gold medal tally at these championships past the 100 mark to highlight the fourth day of action at the IAAF World U20 Championships Bydgoszcz 2016 on Friday (22).

The world U18 heptathlon silver medallist is now the world U20 champion.

With an astonishing comeback on the second day of competition, Switzerland’s Geraldine Ruckstuhl moved from sixth to first and set a championship record of 6037 points to take gold in a thrilling finale to the girls’ heptathlon at the IAAF World Youth Championships, Cali 2015 on Saturday night (18).

If previous form is to be believed, then the girls’ heptathlon should come down to a head-to-head duel between world youth leaders Ukraine’s Alina Shukh and Austria’s Sarah Lagger.

Better known as a winter sports nation, Austria is yet to win a medal at a global age-group athletics championships. But that could all change at the IAAF World Youth Championships, Cali 2015.
