Six-time Paralympic champion David Weir says he has changed his mind on competing for Team GB and will aim to race in the wheelchair marathon at the 2020 Tokyo Games.
Weir, 39, said he would never appear for Team GB again after a disagreement with his coach at the 2016 Rio Games. After winning gold medals at the Paralympics in 2008 and 2012, he missed out on a medal in Rio and said afterwards that his coach accused him of losing on purpose.
The athlete said he went through "the toughest journey" with depression stemming from personal issues following the Rio Games. He split up with his partner in 2017 and moved out of the home he lived in with his four children.
"I'm in such a positive mind-set now," Weir told BBC Sport. "I'm going to make sure I get to Tokyo, put the GB vest on and feel very proud to wear it like I did in 1996 [his first appearance at the Paralympics].
"At the beginning of 2017, my coach, Jenny, and friends could see I was struggling. I found [a counselor] who wasn't involved in sport and didn't know me and during the first conversation I was on the floor in bits, crying.
"I didn't know if I was ever going to race again, I didn't know where my income was coming form. I didn't know what to do, to be honest. It was a whole blur.
"I don't cry a lot so it takes a lot. I didn't realise how deep it went but it started getting better and better each week I was going, and I got stronger."
