Twilight and Sunset times in top running cities

How long after sunset does it take to get dark? The answer is really how much light does that represent? Luckily, they've calculated the angle the sun descends when it becomes too dark for most activities. It is called end of "civil twilight". We've labelled dark in the table above at the time when civil twilight ends. This is essentially when it is too dark to run or do anything outside without a torch.

We list the sunset time on today's date for a few selected cities with good running above. Although in good moonlight, you can run at any time, please make sure to run safely. We recommend to run on roads well before sunset as sunset is when visibility is lowest in a car. Near sunset is a great time to hit the track.
