Concentrated medical demand where no EMS infrastructure exists
TPF’s event and expedition medicine work addresses two related problems. Mass gathering events create concentrated, time-limited medical demand in environments that often lack permanent EMS infrastructure. Expedition medicine addresses care delivery on extended operations where resupply, evacuation, and communication are constrained. TPF supports medical planning, protocol frameworks, and operations design for both.

Event and expedition medicine
Mass gathering events create concentrated, time-limited medical demand in environments that often lack permanent EMS infrastructure. Expedition medicine addresses care delivery on extended operations, remote research stations, prolonged field activities, international expeditions, where resupply, evacuation, and definitive care access are constrained over extended periods.
TPF’s event medicine work is operationalized through the Ultra Medical Team (UMT), a TPF initiative providing evidence-based field medical support, volunteer medical oversight, protocol frameworks, and equipment standards for ultra-endurance sporting events. Ultra-endurance events, trail ultramarathons, adventure races, endurance cycling events, present a distinct clinical profile: high acuity environmental illness, exertional conditions, prolonged high-intensity physiologic stress, and geographically dispersed patients across terrain that does not accommodate standard EMS response.
The research dimension of this work is addressed by the Ultra-Endurance Sports Science & Medicine (UESSM) organization, co-founded by Nick Nudell and Dr. Martin D. Hoffman (UC Davis). UESSM generates the evidence base; the Ultra Medical Team applies it in the field. TPF provides the organizational infrastructure that connects research to operations.
Beyond ultra-endurance events, TPF can support medical planning and operations design for any mass gathering with resource-limited or austere characteristics, remote festivals, endurance competitions, large-scale outdoor events, or international expedition programs.

Where event and expedition medicine sits in TPF’s work
This is one of three practice areas within TPF’s austere and operational medicine pillar. Austere care is defined by what a practitioner has rather than where they are: it describes the clinical and operational problem that arises when conventional EMS infrastructure is absent, overwhelmed, or structurally inaccessible. That is a different problem from the structural fragility of rural and frontier EMS systems, which is addressed on the rural health page. TPF holds both capabilities and keeps them distinct, because protocols written for one fail in the other.
Who this serves. Event and race directors, expedition organizers, endurance sport governing bodies, and venue operators.
