Samsung's latest advert has been criticised by some women's running groups and safety campaigners for being "unrealistic".
The film shows a young woman getting up at 02:00 to go for a run through the streets of a city alone.
Samsung says the aim was to show runners working to their own schedules.
But women's safety group Reclaim These Streets has described it as "tone deaf" in light of the death of Ashling Murphy who was killed on a run in January.
The 23-year-old's death in Tullamore, Ireland, opened up the conversation about how unsafe some women feel running alone, especially at night.
