With 90 members of the UK Team competing at the third Invictus Games in Toronto it can be hard to follow everything the team gets up to.
Throughout the Games we're sitting down with some of the athletes competing to find out what motivates them to push their bodies and minds to the limit and hopefully bring medals back home.
Martin was medically discharged from the Royal Logistic Corps.
The former Lance Corporal was injured in Kabul in 2009, when a suicide bomber drove into his vehicle.
He lost the ability to walk.
While recovering from the attack Martin, like many others competing in the Games, suffered from mental health difficulties which isolated him from his friends and family.
Yet it was those closest to him who helped him through.
It was his partner Becs that signed him up to compete in the games. She told Forces News:
“He watched the Invictus Games with me last year and did not stop talking about it, but he did the typical male thing and didn’t do anything about it so I did it behind his back.”
Martin and Becs have two young sons, Owen and Luke.
The whole family has flown over to Toronto to support him across all his events.
Martin says his struggle with depression 'held him back' stopping him going out in public or being in big crowds.
The Invictus Games has had a profound impact on helping Martin recover.
He told Forces News the Games is really special to him:
"I'm enjoying life again."
Martin is competing in six of the sports at The Invictus Games 2017: rowing, wheelchair rugby, powerlifting, athletics, wheelchair basketball and sitting volleyball.
On the second day of The Invictus Games Martin won a bronze medal in shot put; one of the first medals for Team UK.
