The season’s two best European javelin throwers, who also rank among the world’s top four, are set to face off in what promises to be a thrilling contest: Norway’s Sigrid Borge and Serbia’s Adriana Vilagoš. Lining up against them, Switzerland’s rising star Leonie Hügli, 21, will make her Diamond League debut. Fresh from breaking the Swiss record with a throw of 62.18m in Lucerne, she has every chance of challenging for a podium finish on a good day. The meeting record stands at 68.43m, set by Croatia’s Sara Kolak.
