Use of Image

I understand that during the World Marathon Challenge or in related activities, I may be photographed, filmed, and/or videotaped. I agree to allow my name, photo, video or film likeness to be used for any legitimate promotional purpose by the event holders, producers, sponsors, organizers and assigns.


I certify that I will have adequate insurance to cover unanticipated trip cancellation /interruption, and any injury or damage that may occur on the trip, or which I may suffer while participating, or else I agree to bear the costs of such injury or damage myself and do not hold the organizers responsible for same.

Voluntary Participation and Assumption of Risk

I acknowledge that I have voluntarily applied to participate in the World Marathon Challenge 2025 and that I have carefully read and understand the description, terms, conditions and recommendations of the expedition. I am participating in this trip with full knowledge of the hazards involved in such an endeavor. I also realize that the dates of the trip and locations may change from those specified on this form.

I also understand that Runbuk, Inc. works with a specialist polar logistics company in the organization of the marathon in Antarctica and that I may be required to complete their standard polar travel forms and agree to their conditions.

I understand that Antarctica is the most remote and one of the most inhospitable and undeveloped regions of the planet. Logistics problems are enormous, the weather ferocious and unpredictable. Delays of days or even weeks must be anticipated.

I understand that the risks of traveling and competing in the Antarctic include, without limitation, extreme weather conditions can change rapidly and without warning; that temperatures in January at Novo can fall below -40 degrees Celsius, with wind chills even lower; that bad weather and aircraft malfunction could strand the expedition for many days; that prolonged exposure to the Antarctic environment can even cause loss of fingers, toes, and body parts due to frostbite, or loss of life due to hypothermia, dehydration and other means.

Furthermore I understand that participating in physical activities such as running in the Antarctic area may, in a worst-case scenario, place me at risk of death from the frigid conditions. I fully understand that I am in a remote region devoid of many medical supplies and facilities, as well as rapid evacuation capabilities.

In consideration of being permitted to participate in this trip, I fully assume responsibility upon myself for such bodily, mental, and financial injuries caused by, but not limited to various surface transportation, accidents, aircraft malfunctions, hazards of traveling in the Antarctic environment, forces of nature, civil unrest, terrorism, and other perils. I  freely assume these and all other risks inherent in this Antarctic Expedition, in exchange for the thrill and adventure of traveling to Antarctica.

Furthermore, I understand that I will undoubtedly suffer from a combination of marathon fatigue, jet lag and sleep deprivation as the event progresses onto the other six continents, all of which may have adverse consequences on my health. The impact of wide temperature fluctuations will also be a factor in impacting my health, with a possible variation of 50 Degrees Celsius at minimum. I fully assume responsibility upon myself for these potential adverse health impacts as well as any bodily, mental, and financial injuries caused by, but not limited to various surface transportation, accidents, aircraft malfunctions, hazards of traveling, forces of nature, delays, civil unrest, terrorism, theft, and other perils.

In addition, I am aware that the exact marathon locations and dates may change from those currently outlined in the itinerary.

I understand the World Marathon Challenge 2025 is unique and without comparison to other logistical and physical challenges and there is a real risk the event may not conclude within seven days and will not hold the organizers responsible for same..

I hereby assume all risks, including those mentioned above, as a result of my participation in the World Marathon Challenge 2025.

Runbuk, Inc. reserves the right to cancel the 2025 World Marathon Challenge if it does not reach a minimum level of participants to make it economically feasible to operate. The refund of all monies received will be the limit of our liability. We will not be liable for other costs incurred by you in preparing for the trip.
