The tag alias #46377 racing -> race has been rejected.

Reason: Both mean the same thing; race is the most used of the two at 101 posts compared to racing at 62.

EDIT: The tag alias racing -> race (forum #291104) has been rejected by @Millcore.

Race is mostly used for actual races, whereas racing has a lot of racing-related content such as racing cars.

Posts such as these would be a poor fit under race, disambiguation might work better:

(Looking at the content, we probably should add tags for foot_race, racing_(sports), and hurdling. If those don't already exist under some alternate name.)

I disagree. Race and racing should both be used for the same purpose: an actual race being depicted. racing_jumpsuit or the like shouldn't have that tag.

At first I assumed a 'race' tag would be about biological race tbh, like for scientific or political stuff.
