Women compete in women's bobsleigh (which is always two-woman) and men in both two and four-man competitions. Women were confirmed as being able to compete in any four-"man" bobsleigh event, as from 25 September 2014, either as part of a mixed-sex team or an all-female team. However, because women are on average lighter than men (and thus at a competitive disadvantage in a gravity sport), and because most sliding nations have fewer women able to compete than men, this option has not proved popular with teams.
