Weir, a six-time Paralympic gold medallist, called time on his track career in 2017 following a dispute with coach Jenni Banks.

The 38-year-old claimed Banks had accused him of deliberately throwing a race during the 2016 Paralympic Games in Rio de Janeiro, while also alleging the coach launched his wheelchair across a room.

After learning British Athletics had failed to uphold his complaint, Weir announced he would never represent his country again.

The Briton reiterated that today when asked if he was considering a return to race in the marathon at Tokyo 2020, claiming he was "done" with British Athletics.

Weir also revealed he had battled with depression last year but insisted here today that he was "mentally ready for anything" and that he was "a lot more relaxed" compared with 2017.

"I am really enjoying not being part of the set-up," he said here.

"The marathon is all about you and you are racing for yourself and I feel happy with just doing that.

"There was a lot of pressure on me to always deliver - if it wasn't in the marathon it was on the track."

Wei added: "People put gold medals around my neck before I even got there.

"All of that pressure side is gone now and I can just focus on the races I want to do instead of pleasing others.

"I held a lot of things in when I was here last year to be honest, which was quite difficult."

Weir is set to do battle once again with Hug, the Swiss star who ended his long wait for Paralympic Games gold when he won the T54 marathon and 800 metres events at Rio 2016.

The Briton beat Hug to clinch a record seventh London Marathon title last year.

"I don’t know how strong David is," the 32-year-old Hug, nicknamed the "silver bullet", said.

"It’s his course, he’s from here, he knows everything here.

"I definitely have to think about my plan because last year it didn’t go too well at the end - maybe I have to try something different."
