The first two articles in this series have treated the athlete as a singular being, as one body, one self, one philosophical framework meeting one moment of difficulty. That was a useful simplification. It is also, when you look at how sport and adventure actually unfold, a fiction.
Even the most apparently solitary endeavours are not truly solitary. The solo ultramarathon runner carries the voice of their coach at kilometre 70. The climber on an unroped face is making decisions shaped by years of partnership with others who taught them where to put their hands. The swimmer crossing a channel alone is surrounded by a support boat, a crew, a community of people who made the crossing imaginable in the first place.
This week, we turn outward. What happens to endurance and perdurance when the self in question is not one person, but many?
The philosophical problem of the collective self
Philosophy has long struggled with collective identity. It is relatively clear what it means for an individual to persist through time. We have the two frameworks we have been building in this series to help us think about it. But what does it mean for a team to persist? For a community of athletes to share an identity across seasons, injuries, retirements, and new recruits?
The English football club Sheffield United has existed since 1889. Not a single person alive today played in the founding squad. The stadium has been rebuilt, the kit redesigned, the management changed dozens of times. In what meaningful sense is it the same club? And yet, when a fan speaks of our history, they are not speaking metaphorically. They mean it. The collective self is real to them, as real as their own.
This is the problem of collective endurance and perdurance, and it is not only a philosophical puzzle. It is a lived reality for every team sport athlete, every expedition member, every person who has ever pushed through something hard alongside others.
Collective endurance: the wholly present team
The endurantist model, applied to a collective, produces something remarkable and immediately recognisable to anyone who has played team sport at a high level: the experience of a group that is, in a particular moment, completely unified.
Call it cohesion, call it chemistry, call it being on, every team athlete knows the sensation. The defensive line that moves as a single organism. The rowing eight whose blades enter the water with a synchrony that feels less like coordination and more like one body doing one thing. The trail running relay team in which each runner carries not just a baton but the accumulated effort and sacrifice of everyone who ran before them.
This is collective endurance in its philosophical sense. The team is wholly present, at this moment, as a continuous and unified entity. Individual identities have not disappeared but have become temporarily subordinate to something larger. The pain of one becomes distributed across many. The doubt of one is absorbed and neutralised by the certainty of others.
Research in sports psychology has consistently found that athletes in high-cohesion teams report higher pain thresholds during shared efforts. This is not merely motivational. It appears to be physiological, the presence of others engaged in the same struggle genuinely alters the experience of difficulty. The collective endurant self is not a metaphor. It changes the body.
But collective endurance carries the same trap as its individual counterpart, just slightly amplified. A team that exists only in its moments of total unity is fragile in the spaces between those moments. The locker room after a heavy defeat, the off-season, the period of rebuilding after key players leave. A collective identity built entirely on shared present-moment intensity has nothing to hold it together when the intensity is gone. Teams that peak and then collapse often suffer from this exactly : they were brilliant endurant collectives who never built anything to last.
Collective perdurance: the club that outlives its players
The perdurantist model of collective identity is, in many ways, more intuitive when applied to groups than to individuals. We already think about institutions, clubs, and teams as four-dimensional entities almost automatically. The New Zealand All Blacks are not the fifteen men on the field this Saturday. They are a temporal object extended across more than a century of rugby, incorporating thousands of players, hundreds of matches, victories and defeats that living players were not alive to see but nonetheless feel as part of their own story.
This is collective perdurance: the understanding that the team exists as a long shape through time, and that each current member is a temporal part of that larger whole rather than its complete expression.
The practical consequences of this framework are profound. When a young player joins a club with a powerful perduring identity, they are not asked to build something from scratch. They are asked to carry something forward. The weight of history is real but it is also a scaffold. You do not need to construct an identity under pressure because the identity already exists, already has weight and direction, and you are its current custodian.
The Haka, performed by the All Blacks before every match, is one of the most visible expressions of collective perdurance in world sport. It is not a motivational exercise invented for the team currently on the field. It is a ritual connection to a line of predecessors extending back to generations. Each player performing it is explicitly locating themselves in a temporal whole that is much larger than their individual career. They are not the team. They are one temporal part of it and that part comes with responsibilities to all the other parts, past and future.
Adventure expeditions develop similar structures, often less formally. The tradition of a particular climbing club, the unwritten code of conduct on a long sailing passage, the shared history of an expedition team who has been in the mountains together before; these are all forms of collective perdurance, giving individuals a larger story to inhabit when their individual story is running thin.
When the collective carries you
There is a specific experience that sits at the intersection of collective endurance and perdurance, and it deserves its own space: the moment when you cannot continue alone, and the group makes continuation possible.
It happens in races. It happens on expeditions. It happens in the third set of a team sport match when the legs are gone and the deficit seems insurmountable. Individually, the athlete has reached their limit. The personal story has no obvious next chapter but the collective story is still going, and it pulls you along with it.
This is not weakness. It is one of the most philosophically interesting phenomena in all of sport. The self, in these moments, is genuinely extended beyond its individual boundaries. The effort being made is not entirely yours. The will sustaining you is partially borrowed and the extraordinary thing is that this borrowed will is not metaphorical; it produces real physical output, real metres covered, real weight lifted.
Philosophers of collective action debate whether groups can have genuine agency, or whether a team can decide or intend or persist in the same way an individual can. Sport suggests the answer is yes, and it suggests it viscerally, in the moment, to everyone who has ever been carried by a collective when they could not carry themselves.
The question for any athlete or adventurer, then, is not just how do I build my own endurance and perdurance? It is: what collective am I part of, and how does its temporal identity sustain mine?
The obligation that flows the other way
So far we have spoken about what the collective gives to the individual, but the philosophical relationship runs in both directions.
The endurantist collective makes demands on its members in the present. To be wholly part of a team in this moment is to accept that your individual performance is never entirely private. Your effort, or lack of it, is felt by everyone around you. The rower who checks out at stroke thirty changes the hydrodynamics of the entire boat. The defender who switches off for one second changes the game. Collective endurance creates a form of accountability that individual endurance cannot, and it's the knowledge that your presence in the moment is not just about you.
The perdurantist collective makes a different kind of demand: stewardship. If the club, the team, the expedition group is a four-dimensional entity extended through time, then the current members are not its owners. They are its custodians. They received something from those who came before, and they are obligated to pass something forward to those who come after. Leaving a team better than you found it is not merely a sporting cliché. It is a genuine philosophical responsibility because you are shaping a temporal object that will outlast you.
This is why great team captains and expedition leaders often speak in a particular register that sounds slightly strange in the individualistic context of modern sport. They speak of the shirt, the rope, the flag with a reverence that seems disproportionate until you understand that they are not talking about fabric. They are talking about a perduring self that they are temporarily carrying, and for which they feel real responsibility.
Grief, transition and the collective self
One of the most painful experiences in team sport is the dissolution of a great collective. The Olympic team that is never quite the same after the Games. The club side that wins everything one season and fragments the next as players move on. The expedition group that climbs something extraordinary together and then scatters back to their separate lives.
From an endurantist perspective, this dissolution feels like death. The thing that existed, that fully present, wholly unified collective self, no longer exists, and in a meaningful sense, that is true. You cannot reconstruct that exact team, that exact chemistry, that exact shared presence. It is gone.
From a perdurantist perspective, the dissolution looks different. The collective still exists as a temporal object; it existed, which means it is part of the permanent fabric of what has happened. The team that won in 1988 is a real part of the club's four-dimensional story, even though non of those players remain. The athletes who shared an extraordinary expedition carry a temporal part of a collective self that is now dispersed, but the part they carry is real, and it continues to shape who they are individually, long after the group has separated.
This is why reunions of great teams feel so charged. It is not mere nostalgia. It is the temporary reconstitution of a perduring collective self, a gathering of temporal parts that briefly, vividly, bring the whole back into focus.
Building the collective you want to be part of
All of this has a practical implication that is easy to overlook: collectives are made, not found.
The team culture that will carry you at kilometre 80 is being built in the conversations you have in training. The expedition group that will hold together through a three-day storm is being shaped by the decisions you make about honesty and vulnerability before the weather turns. The club identity that will give young athletes a story larger than themselves is being authored by everyone currently inside it.
Endurance and perdurance, understood individually, are qualities you can cultivate alone through training, philosophy and through the accumulation of difficult experiences. But collective endurance and perdurance require something more. They require the deliberate construction of shared meaning: common rituals, shared history, honest communication, and the explicit understanding that the group is something more than the sum of its current members.
This is harder than individual resilience. It requires trust, which is slow to build and fast to destroy. It requires leaders willing to subordinate their own temporal slice to the longer story of the collective. It requires members willing to be fully present to each other, not just to the task.
But when it works, when a collective genuinely endures and perdures together, it produces something that no amount of individual toughness can replicate: the experience of being held by something larger than yourself, and holding it in return.
