The one-day race travels across the Ardennes Mountains and ends atop the famous Mur de Huy. 

The men's field includes France's road race world champion Julian Alaphilippe of Quick-Step Alpha Vinyl Team and Tour de France winner Tadej Pogačar of UAE Team Emirates and Slovenia. 

Pole Michał Kwiatkowski of Ineos Grenadiers is also expected to be in contention for victory alongside 41-year-old Spaniard Alejandro Valverde of Movistar and Italian Vincenzo Nibali of the Astana Qazaqstan team. 

Valverde, who holds the record for the most wins in the race with five altogether, has confirmed that he will retire after the 2022 season. 

He first triumphed at La Flèche Wallonne in 2006 and managed to add four consecutive victories from 2014 to 2017.

Kwiatkowski won another Classic, the Amstel Gold Race, by the narrowest of margins earlier this month, edging Frenchman Benoît Cosnefroy of AG2R Citroën Team.

Pogačar's Slovenian compatriot Primož Roglič of Team Jumbo-Visma, who managed to finish second last year, is not racing as he continues to recover from a knee injury. 

Alaphilippe took his third Flèche Wallonne victory at the race last year, while Pogačar has started the race twice before, finishing ninth in 2020.

Belgian Remco Evenepoel of Quick-Step Alpha Vinyl Team will be making his La Flèche Wallonne debut in tomorrow's race.

In the women's event, Annemiek van Vleuten of Movistar is eager to claim the title as she has missed out the top spot twice at this race.

Fellow Dutch rider Demi Vollering of SD Worx, Pole Katarzyna Niewiadoma of Canyon-SRAM plus Elisa Longo Borghini of Italy and Trek-Segafredo are also included on the start list.

Vollering earned silver at the Amstel Gold Race after finishing four seconds behind a different Italian, Marta Cavalli of FDJ Nouvelle-Aquitaine Futuroscope. 

Niewiadoma won the Amstel Gold Race in 2019, while Borghini powered to victory in the Paris-Roubaix earlier this week. 

The men’s race dates back to 1936, while La Flèche Wallonne Féminine was first staged in 1998.
