The prominent purple text "RUNNING" overlaid on the iconic Tower Bridge.

The video opens with a close-up of Tower Bridge in London, with the word "RUNNING" overlaid in large purple text. It then transitions to a woman stretching in front of the bridge, with the text "RUNNING THE LONDON MARATHON?" appearing. The scene shifts to a close-up of the woman's face, with the text "START YOUR FUNDRAISING" appearing. Finally, the woman is shown running through a street in London, with the words "MAKE EVERY STEP COUNT" and the JustGiving logo appearing. The pacing is quick and energetic, with text overlays appearing and disappearing rapidly.
