If you set up segments on a race route, you effectively can get splits from those who do the race and download to strava (or run the race route at any other time!). Though it only really works for the sections of races where there is little route choice as I think there's only a limited tolerance in terms of deviation off the route from A to B when 'doing' a segment. But for races on paths for sure it would work well. So you could for example get climb and descent splits within a race.
