The rising star announced he had been diagnosed with cancer in January 2020 and underwent surgery to remove a tumour a week later.
More challenges followed, with the 25-year-old having a particularly tough end to last year as he completed two cycles of chemotherapy following “complex abdominal surgery”.
“It was the hardest thing I’ve ever had to do in my life,” Randle said.
“During the process, the days went by so slow but now it’s pretty incredible to think that six months have passed.
“I haven’t had much of a break, but it’s nice to be doing things.
“I feel fine, I feel back to normal, I’m certainly thankful for all the people that have treated me, oncologists’ doctors, nurses, my family and supporters.
A warm, happy and positive person in the paddock, Randle has continued to impress on track, most recently pulling off a Daniel Ricciardo-like overtake on Anton De Pasquale in the Merlin Darwin Triple Crown finale, after netting ninth in Race 12 on Saturday.
Randle was a standout at the OTR SuperSprint, again avoiding drama in the first Sunday race to finish eighth.

“When you go through a major health challenge, it puts life not necessarily in question, but you step back and think what is important in life,” said Randle.
“Firstly family and those that surrounded me with love and support, but also, my own hopes and aspirations and what do I think is important to me.
“I’ve wound up in the seat of a race car, so I think I know what I want to do in life.
“Going through what I went through certainly helped when I’m presented with other challenges in life, it certainly can’t be worse than what I went through back then.
“My outlook on a lot of things is there are people that are going through a lot worse things in life.
“And a bad day at the race track is still a very, very good day because there are so many people who would love to be doing what we are doing.
“That’s the way I would like to look at it, I’m certainly very thankful to be where I am. I’m extremely grateful to be in the position I'm in."

Randle, who will co-drive for Tickford Racing at October’s Repco Bathurst 1000, continues to raise awareness about testicular cancer.
“The message is that if you feel something not quite right, don’t hold back, have the courage to seek out your GP and medical professional that’s what they’re trained in,” Randle added.
“It’s the same with a race car, if there’s a problem, you get it diagnosed and fix it.
“Our human body is not much different, and it could be the difference between saving your life.
“We are seeing it more and more these days if you can pick it up early the odds of it cured or going into remission are much, much higher.”
