They will race on a version of the same course just a few hours before the stage 13 time trial of the Tour de France takes place there. 

The course consists of just under five laps of the 27 kilometres circuit to be used for the men's event for a total of 121km.

A group of 21 six-women teams are expected to start the race. 

The route will include climbs over the Côte d’Esquillot and Cite de Gelos, which organisers claim could suit the one-day classics specialists but also give the sprinters a chance.

In 2018, the event returned to a one-day format, a road race linking Annecy to a finish in Le Grand-Bornand, won by Dutch rider Annemiek van Vleuten in a showdown against compatriot Anna van der Breggen.

It was van Vleuten's second consecutive victory having also won in 2017. 

The favourite tomorrow is expected to be another Dutch rider, the 2012 Olympic road race gold medallist Marianne Vos, who did not take part in last year's La Course event. 

The CCC-Liv rider arrives at the event having won four stages of the Giro Rosa, including the final one in Udine on Sunday (July 14).

Victory would represent the second triumph for Vos in La Course, five years after taking the inaugural edition on the Champs-Élysées.

The overall general classification of the Giro Rosa was won by van Vleuten, whose participation tomorrow was only confirmed this afternoon.

It means all the former winners of the race will be on the start line.

Van der Breggen, the runner-up in the Giro Rosa and the 2015 La Course champion, is set to challenge Vos.

She will be joined by another La Course champion, Australia's Chloe Hosking, the 2016 winner.
