Problem of the week

Two cyclists KUN and MIN, start from a point 100 KM apart ; As they start, a bee takes off from

 the nose of cyclist KUN and heads towards MIN’s nose, proceeding at 20 KM per hour.

 The instant it alights on MIN’s nose, it turns back and heads towards KUN’s nose.

It continues this back and forth movement, doing shorter and shorter stretches

 until finally it gets squashed  between the noses of the two cyclists.

 How much distance does the bee travel before the Big Bang comes ?
