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.
