I just cannot find the proper word for a car race (as well as other kinds of races). PIV and ReVo suggest vetkuro for a competition between sport contestants (ReVo: Kuro inter sportaj konkuranto) but the kuro part of the word makes me feel odd, as cars don't have legs to run. There are also konkuro and konkurso but they do not really capture the meaning, or at least that is how I understand them.
So, is any of those words applicable or are there others that capture the meaning better? Or should the concept be described with more words?
