In January 2017 we asked children across the country to submit their designs for the IAAF World Championships mascot.

The rules were simple:

* They needed to head over to the Blue Peter website and download a competition entry form
* Fill in all the required details and design a mascot for the Championships
* It could be any shape or size, an object, animal or even a superhero! Whatever they wanted it to be

The competition is being run in conjunction with Blue Peter and previous World Champions Dame Jess Ennis-Hill and Richard Whitehead are on the judging panel.

The lucky winner will not only see their designs come to life, they will also be invited on to Blue Peter to unveil their winning entry.

Details of the winner and thier design will be published here once announced.
