London 2017 have unveiled the medals for the International Association of Athletics Federations (IAAF) World Championships and the World Para Athletics Championships.

The medals "place the drive and determination of athletes at the heart of a unique clockwork design", organisers have claimed.

Designed in the shape of an athletics track, both sets of medals include symbols of every event for each schedule.

The medals for the IAAF World Championships also feature iconic London landmarks that sit on the River Thames, including Tower Bridge, the London Eye, The Shard and Big Ben.

For the World Para Athletics Championships, "layers" of equipment will allow visually impaired athletes to feel the detail on the medals.

"We are very proud of the unique medal designs for both the World Para Athletics Championships and the IAAF World Championships London 2017," said Niels de Vos, Championships Director.

"It isn't easy to demonstrate so much on a medal but Toye, Kenning and Spencer have done a fantastic job with a design that carries such a great message.

"There are 213 medal events at the World Para Athletics Championships and 47 medal events at the IAAF World Championships and every athlete dreams of standing on the podium to collect one.

"Hopefully we have made that moment even more special by presenting a truly unique medal."

Athletes Dan Greaves and Jazmin Sawyers were included on a creative panel that fed into the design process, along with coach Toni Minichiello.

For the first time at the Championships, medals will also be given to coaches who help to prepare athletes for competition.

"The IAAF World Championships London 2017 is going to be a fantastic event and that organisers are recognising the coaches of medal-winning athletes with a medal for the first time too is a great progressive step," said Minichiello, who guided London 2012 Olympic heptathlon champion Jessica Ennis-Hill.

"A coach works very closely with athletes and it's important to understand what makes them tick.

"It is great to see that element being applied to the medals.

"At a big event like a World Championships, mindset and good decision making at the right time makes the difference between being successful and not."

The World Para Athletics Championships will take place at the London Stadium from July 14 to 23.

The IAAF World Championships follow from August 4 to 13.
