Dunkin' Donuts "Marathon motivator" by Martin London

Dunkin' Donuts' "Marathon motivator" campaign kicked off on social media in the lead up to the London Marathon on the 23 April 2017.

The digital activity features a film that spoofs 1980s shopping channels. It stars a Jane Fonda-esque fitness fan modelling a giant donut strapped to her head. The donut dangles about 18 inches from her face, from a headpiece designed for runners.

The headgear was worn by Scott Montgomery when he ran the 2017 London Marathon. During the race he also sported a Dunkin’ Donut’s branded outfit bearing the message "Just Donut".

In return, Dunkin’ Donuts donated £2,000 to Montgomery's charity, Children with Cancer UK.
