The Olympic athletics is about to kick-off in Tokyo's main stadium, with lots of medal opportunities for Team GB. 

Some of the UK's most famous former athletes will line the sofa for the BBC's track and field coverage, including face of London 2012 and double Olympic heptathlon medalist Jessica Ennis-Hill. 

It's an event GB has seen much success in, with fellow former heptathlete and Olympic champion Denise Lewis joining Jess in the studio. 

Colin Jackson and Michael Johnson are familiar faces on the athletics punditry scene, and with the addition of Jeanette Kwakye, the group make a well rounded team.

But what were their specialities? 

Here's what you need to know about the BBC athletics pundit team.

Who are the BBC Olympic athletics pundits?

During the last Olympics it was Jessica Ennis-Hill the pundits were discussing, but this year she is joining them in the studio having retired after Rio. 

It is hard to forget the iconic moment Jess won gold on Super Saturday in 2012, and as one of GB's greatest medal hopes that year, she will understand the  pressure the likes of Dina Asher-Smith faces this year.

Denise Lewis is another heptathlon champion and was a key member London 2012 Olympic bid team. 

She has been a mentor to Katarina Johnson-Thompson, the world champion heptathlete who hopes to follow in the footsteps of Jess and Denise. 

Michael Johnson has worked with the BBC for years following a immensely successful career which saw him win four Olympic golds. 

The American specialised in the 200m and the 400m, and in 2000 became the only man ever to defend a 400m Olympic title. 

Colin Jackson is a Welsh former sprint hurdler who won silver in the 1988 Olympics. 

Like Denise, he was part of the 2012 Olympic bid team and has worked on the BBC Olympic athletics coverage since 2004. 

Finally, Jeanette Kwakye rounds up the pundit team as a former British champion sprinter and Olympic finallist. 

As a 100m and 200m runner, she will likely offer insight into the training programme of Dina Asher-Smith, one of GB's biggest hopes for gold.

Following her retirement in 2014, she completed her NCTJ qualification before joining BBC Sport.
