Each October, millions of Australians are invited to move through 60 kilometres of chosen terrain — not merely for fitness, but as an act of witness. The Red Sock Challenge, run by Kidney Health Australia, holds space for the 2.7 million Australians living with kidney disease, most of whom do not yet know it. In a condition that can erase 90 per cent of organ function before a single symptom surfaces, awareness itself becomes a form of medicine — and every kilometre walked is a quiet argument against silence.
Red Sock Challenge Rallies Australians to Support Kidney Disease Awareness
2.7 million Australians live with kidney disease, with many unaware of their condition until significant progression; dialysis patients require 60 hours monthly of machine-dependent treatment.
Kidney disease progresses silently for years without symptoms

So the challenge is literally 60 kilometres in a month? That's not that much—that's less than two kilometres a day if you spread it out.
Mimi
Right, and that's intentional. They're not asking people to run marathons. They're saying: move in whatever way your life allows. Walk to work a few extra times, swim on weekends, cycle around your neighbourhood. The 60 kilometres is the symbol—it represents the 60 hours dialysis patients spend on machines every month.
Luke
But I want to be clear on the numbers. The source says 2.7 million Australians have kidney disease, and 2.5 million are unaware. That's a pretty specific figure. Do we know if that's from a study, or is it an estimate from Kidney Health Australia itself?
Mimi
That's a fair question. The source attributes it to the campaign material, so it's likely from their research or a health survey, but the original study isn't named in what we have.
Mark
And the 90 per cent figure—that up to 90 per cent of kidney function can be lost before symptoms show—that's the thing that makes this a "silent disease."
Mimi
Exactly. You can lose most of your kidney function and feel fine. That's why early detection matters so much. By the time someone feels sick, they might already need dialysis.
Luke
The red socks—is there evidence that dialysis patients actually feel particularly cold, or is that more of a symbolic choice?
Mimi
The source says dialysis patients "often feel cold during the 5-hour long dialysis sessions, particularly in their feet." So it's grounded in the actual experience, not invented symbolism.
Mark
So wearing red socks is a way of saying, "I understand what you're going through."
Mimi
And it's a conversation starter. Someone sees your red socks and asks why you're wearing them, and suddenly you're talking about kidney disease.
Luke
One more thing—the campaign runs in October, but we don't know yet how many people will participate or how much money will be raised. This is a call to action, not a report on results.
Mark
So we're at the beginning of something, not looking back at what happened.
Mimi
Right. The challenge is just starting.
Le Pouls
- A disease affecting 2.7 million Australians goes largely undetected because it offers no warning until the damage is already profound.
- The 60-kilometre target is not a fitness goal but a reckoning — it mirrors the 60 hours dialysis patients spend machine-bound every single month just to stay alive.
- Red socks, worn by participants, carry the weight of solidarity: dialysis sessions leave patients bitterly cold, and the symbol bridges the gap between those inside the experience and those watching from outside.
- Kidney Health Australia is betting that movement creates conversation, and conversation creates the early detection that late diagnosis so cruelly forecloses.
- The campaign asks nothing extraordinary — a walk, a swim, a ride — only that Australians name kidney disease aloud and make it, for once, a little less silent.
Each October, millions of Australians are invited to move through 60 kilometres of chosen terrain — not merely for fitness, but as an act of witness. The Red Sock Challenge, run by Kidney Health Australia, holds space for the 2.7 million Australians living with kidney disease, most of whom do not yet know it. In a condition that can erase 90 per cent of organ function before a single symptom surfaces, awareness itself becomes a form of medicine — and every kilometre walked is a quiet argument against silence.
Every October, Kidney Health Australia asks Australians to cover 60 kilometres however they choose — on foot, in water, by bike — across the span of a month. The number is deliberate. It mirrors the 60 hours that dialysis patients spend connected to machines each month, their survival measured in filtered hours and cold plastic tubing.
The campaign exists because kidney disease is, above all, a quiet one. Of the 2.7 million Australians living with it, an estimated 2.5 million have no idea. The disease can consume up to 90 per cent of kidney function before a person feels anything at all — which means that by the time a diagnosis arrives, the window for meaningful intervention has often already closed.
The red socks worn by participants speak to something specific: dialysis sessions, which run for five hours and repeat several times a week, leave patients intensely cold, especially in their extremities. The socks are a gesture of warmth and understanding — a way of saying that those on the outside have tried to imagine what the inside feels like.
Kidney Health Australia's CEO Chris Forbes puts the stakes plainly: people are routinely diagnosed too late, after years of silent progression. Early detection changes everything — it opens doors to management, to slowing the disease, to choice. Late detection closes them.
The challenge is framed not as athletic ambition but as an invitation to conversation. Each kilometre is a chance to say the words 'kidney disease' to someone who might not have heard them before — and in doing so, to make this silent condition a little harder to ignore.
Every October, Kidney Health Australia invites Australians to move their bodies in whatever way suits them—a walk with friends, a run before dawn, laps in a pool, a weekend bike ride—and cover 60 kilometres over the month. The distance is not arbitrary. It represents the hours that people on dialysis spend tethered to a machine each month just to survive: 60 hours of their lives, every single month, filtered through plastic tubes and needles.
The Red Sock Challenge is an annual campaign designed to raise awareness and funds for kidney disease, a condition that affects 2.7 million Australians. The scale of that number becomes sharper when you learn that 2.5 million of those people do not know they have it. Kidney disease earns the nickname "silent disease" because it progresses without announcing itself. Up to 90 per cent of kidney function can vanish before a person feels anything wrong. By the time symptoms arrive, the disease has often advanced far beyond the point where early intervention might have helped.
The red socks themselves carry meaning. People undergoing dialysis sessions—which last five hours and happen multiple times a week—often feel intensely cold, particularly in their extremities. The socks are a symbol of warmth, of solidarity, of someone on the outside understanding what it feels like to be on the inside of that experience. Participants are encouraged to purchase a pair as part of their participation, though the core of the challenge is simply the movement: 60 kilometres completed however the person chooses, at whatever pace their life allows.
Chris Forbes, the Chief Executive Officer of Kidney Health Australia, frames the challenge around a central problem: most Australians do not know they are at risk. "Kidney disease can progress silently for years without symptoms, meaning people are often diagnosed too late," he said. The gap between having a disease and knowing you have it is where lives change. Early detection matters enormously. A person who learns they have kidney disease while they still have function can manage it, slow its progression, make choices about their treatment. A person who learns too late may find themselves with no choice at all—only dialysis, only those 60 hours a month, only the cold.
The challenge invites Australians to "pull their socks up" and take on the 60 kilometres, framed not as a gruelling athletic feat but as an act of conversation-starting. Every kilometre walked or run or swum or cycled is an opportunity to tell someone why you are doing it, to name kidney disease aloud, to make it less silent. The campaign runs throughout October, and participants of any fitness level are welcome. The point is not to break records. The point is to move, to raise funds, and to help spark the awareness that might catch kidney disease before it catches someone unaware.
