~3 miles of my commute is along a paved greenway trail, now mostly covered in leaves. My tactic for riding through them when wet is the same as for crossing the wet boardwalks also on the greenway: slow down beforehand, then ride as steady and as straight as possible while assuming I will go down at any moment, and being prepared for that. Some turny sections of boardwalk I stop and walk the bike through, then remount.
