Tim G's does a "saturday" race need special taper?

My A race is a Saturday, and in Europe which really means Friday evening on my true life schedule. I have figured out how I will address race week given the travel and such. However, I am wondering whether there is any merit in moving the weeknd before Saturday bike to like Friday. The race is ITU long course worlds in France 4k-110k-30k so longer than a half and not as long as full. I have penciled in a ride of 2.5 hrs sat weekend before with sun off.
