The American speedsters should dominate this race. Noah Lyles, at 21 years old, holds the fastest time (19.69) of those taking the starting line and has just proven his pedigree by winning the US Championships over 100m. Isiah Young (19.93) is making strides. Michael Norman (20), world U20 champion and new world record holder in the 400m indoor will be ready to challenge them. The others lining up are Jereem Richards (TTO) who has already run a sub-20 seconds this year and Christophe Lemaitre (FRA) who wants to confirm his level of fitness. Edward Alonso (PAN) completes this prestigious field and the Swiss Alex Wilson will have a great opportunity to improve on his recent national record.
