(CNN) After a sensational opener in Doha last month, the Longines Global Champions Tour is heading to Mexico City for the keenly awaited second leg.

Anticipation is already building in the bustling Mexican capital which has proved to be a popular stop on the tour since 2016.

The Campo Marte course offers a wonderful setting where the world's best horses compete at 2,250 meters (7,381 feet) above sea level.

However, Julien Epaillard, who edged defending champion Ben Maher in the first leg in Qatar, is not competing this weekend.

The Frenchman's absence leaves the door open for the likes of Maher, Edwina Tops-Alexander, Harrie Smolders and Scott Brash to overtake Epaillard in the race for the 2019 title.
