individual ways that have the direction, not the entire relation.
some routes (made of many overlapping pieces of trail) are considered
ascents and decents. the named “trail" is made of the ascent route and
descent route.
tagging Mt fuji is the opposite of a trail hundreds or thousands of Km
long - it’s a few routes less than 10 KM long used by thousands of
people every day of the season.

The colors are the different trails. the dashed lines are the descent
routes. there are overlapping ascent and decent routes from different
trails (subashiri & Yoshida between the summit and 8th station) and
shared paths/tracks as well.
it would be nice to be able to tag the ascent/descent/both.
If the route is considered to be a return then I would map it like a
public transport version 2 route
from the start/finish
way 1 role forward
way 2 (assent) role forward
way3 role forward
(top)
way 3 role backwards
way 4 (decent) role forward
way 1 role backwards

The elevation profile will give you assent/decent info. Are ways 2 & 4
one way? If so you could use the description key on those ways to say
assent/decent?
But ways 1&3 are 2 way.
Problem with the above .. you could not easily split one route at the
top to use another route to descend. If the accent and decent were
different relations then it would be easier, and each relation can have
the assent.decent description. Of course both these routes could be
included into a relation to combine them with the name etc.
???
I mentioned this in the comments, but the answer didn’t seem to
address the issue directly.
also - does the relation need intersection/junction nodes?
I don't think so.
also also - links?
What links? urls? or do you mean ways that connect the route to
bus/train/etc? In which case I think those can be role approach ?
