Not sure they do manage absolutely fine – they are a bottomless pit for running costs, but whilst there is snow, they make a small fortune due to the numbers opf people skiing. MTB is a much smaller number so far less money to make from punters (and we all read how many folk don’t like paying for just car parking!).
Skiing has far more money in it so costs are more likely to be ‘manageable’, but as we’ve seen over the last couple of sessions in Scotland, with numbers down, things aren’t as rosey for them either…
Suspect ebikes are going to have a major impact (for the worse) on climbs (from what I’ve seen and witnessed – hopefully this is the minority)…they just speed up erosion and a number just don’t seem to bother about how they are ridden (which also helps speed up erosion). Plenty of ebike riders do seem to be considerate, but many aren’t. Saying that suspect the trail design will take that into account as ebikes are now incredibly popular.
