You’ll probably do something like 25-30 miles cycling in some pretty cack muddy conditions (who knows, might be dry, -15 and frozen solid, we can hope). The mud’s pretty abrasive stuff – but it’s not really anything _that_ nasty.
You’ll go through a few sets of brake pads – and do some wear on the chain/sprockets. Not really any worse than any other winter riding.
I think the last one (2011), I went through a few sets of pads and the cables needed replaced afterwards, but that was the extent of the carnage. I tend to go through suspension bearings on an annual basis but I don’t think ‘Puffer contributes to this massively.
EDIT – second trail_rat on the worn kit – not worth the risk. It’ll be cold and muddy – do you really want to have to do any more trailside repairs than you have to?
