KEY POINTS:
When the going gets tough in next month's Auckland Marathon, runners will be encouraged to visualise themselves as a "little yellow rubber duck", because it always rises to the surface and always bounces back.
The mental image is being pushed by marathon sponsor adidas in the build-up to the big event on November 2.
To help get the message across, a giant inflatable duck is making its way around the city, ending up at Mission Bay this weekend in time for a fun-run relay.
