Noah Lyles in the 60m, Josh Kerr in the 3,000m, Mondo Duplantis in the pole vault or even Karsten Warholm in the 400m… These are the male headliners of these indoor worlds in Glasgow.
All these champions will be looking for confidence and results in Scotland.
An ideal way to prepare for the Paris Olympics, which are fast approaching.
Among the men, some French people will also be present in Glasgow.
Thibaut Collet, who is coming off a convincing All Star Perch in Clermont, will be the leader of the French men's delegation.
It will also be necessary to monitor the performances of Wilhem Belocian and Just Kwaou Mathey in the 60m hurdles.
