Gabby Logan introduces highlights of the ninth Diamond League meeting of the year from Lausanne, with six-time Olympic champion Usain Bolt one of a host of world-record holders taking to the track in Switzerland.

Bolt will contest the 200m in Lausanne and will be joined by fellow Olympic champion and world-record holder David Rudisha in the 800m.

French pole vaulter Renaud Lavillenie also holds the world record and will strut his stuff in Switzerland at the Pontaise stadium.

There is no shortage of big names in the women's events with Olympic gold medallist Allyson Felix taking on European champion Dafne Schippers over 200m, and London 2012 champion Sally Pearson running in the 100m hurdles.
