I'm getting a feeling that there should be a grave accent in there. Vallières
		
		
	 
This is correct, with correct spelling.  Why most written reports do not include it is outside of my limited knowledge.  Maybe it is something against french speakers. 
I would certainly expect a sports governing body to provide correct spellings, maybe naively*.  The UCI website results of the women elite road race excludes Vallieres' accent, includes Garcia Canellas' (3rd), excludes PFP's (16th)** and includes Ruegg's (20th).
* yes, I know there should be something over the "i" but I don't know what its called or how to find it on my keyboard.
** and Prevot should probably have 2 accents, as in Prévôt !!
