Thick fog in the Caucasus mountains on Monday morning has delayed the start of men's snowboard cross Olympic competition, which will now go ahead without the scheduled seeding runs, organisers said. Originally due to start at 1100 local time (0700GMT), fog and drizzle shrouded the course. After an initial postponement, conditions remained bad and organisers decided to cancel the seeding runs and plan to go straight into the finals runs, starting at 13.30 local time.
