Michael McKillop was extremely emotional after winning his fourth Paralympic gold medal in the T37 1500m. When you hear about the five weeks he's had - it's not hard to understand why.
The 26-year-old stormed to victory in Rio yesterday, but five weeks ago he didn't even know if he would compete at the games.
Speaking to Newstalk after his victory, McKillop revealed the true extent of his injuries. McKillop said that he ran 4.30 in a race just five weeks ago - that would have been 18 seconds slower than what he ran on Sunday - and that things weren't good afterwards:
I had vitamin B12 deficiency, I struggled to get out of bed. At times I couldn't really train, so going into the Paralympic Games was a massive risk.
I had a foot injury as well. A couple of bones in my right foot have fused together and are causing a lot of pain when I wake up in the morning or if I sit for long periods of time.
The four-time Paralympic champion credits a lot of his success to his team, his physios and doctors who helped him train enough to get him to Rio without running him into the ground.
McKillop was able to stroll to the line in first place yesterday in a remarkable performance - which now looks even more heroic when you consider what he's been through just in the last month.
