4 BRIT MEDAL HOPES

CJ UJAH: A PB of 9.96sec and three Diamond League wins this season. By far Britain’s form sprinter. Outside shot at 100m medal. NETHANEEL

MITCHELL-BLAKE: A 19.95sec runner in the 200m and outside shot at a medal with no Bolt in the event.

4x100m MEN: Excellent depth, with three of the squad (Ujah, Adam Gemili, Mitchell-Blake) having gone sub-10sec. 4x100m WOMEN: Took Olympic bronze in Rio but could struggle this year with Dina Asher-Smith yet to find true form after foot injury.
