Jungle Marathon

Dates and Event Details for the 2018 Event will be Advised Shortly

The Jungle Marathon, the world's wildest eco race, gives competitors the opportunity to combine sport and eco tourism, while experiencing this stunning part of the world.

The Jungle Marathon offers three races: a marathon; a 4 stage 127km race and a 6 stage 254km race. The course, which includes swamps, river crossings, steep climbs and descents, village trails and fluvial beaches, combined with humidity and scorching temperatures makes it a daunting and exciting race, but well within the realms of any competitor who has a strong mental mindset.

Yes, physical fitness is a requirement  but if you don’t have strong mental tenacity to combine with it then you will struggle to reach the finish.

If you are ready for one of the most exciting  and challenging adventures of your life, sign up today and join the Jungle Marathon in October in The Flona Tapajos, near Santarem, Amazonia, Brazil for the12th edition of the legendary Jungle Marathon.

Whether you do 42km, 127km or 254km, you will NEVER forget this adventure.


The race offers three options- either 42km, 127km or 254km. Those choosing the marathon will have three days of acclimatisation before you race. This will include some accompanied hikes and short runs into the jungle. After your marathon there will be some eco- tourism arranged. The runners in the 127km distance will continue to experience the jungle environment until the finish of the 254km race and will then attend the prize giving and race wrap party. Competitors in all distances are required to be self-sufficient from their arrival in Brazil until the finish lunch at the end of the 254km stage.

Jungle Marathon – An Extreme Race

You need to be fully aware that Jungle Marathon takes place in a remote and potentially dangerous environment. Apart from the dangers of the jungle itself, where you may be exposed to snakes, wild animals and poisonous plants, you are also going to be racing in a hot humid environment. Heat exhaustion, dehydration and problems with salt/electrolyte balance are real dangers. The organisers take safety very seriously and make every effort to minimise risk, but please be aware of the potential hostilities and ensure that you have fully considered these points before you proceed with your entry. The complete “Your Safety” document will be forwarded to you prior to your registration.

Medical & Technical Assistance

Technical and ground assistance is provided by Brazilian and European personnel experienced in ultra events, jungle adventure trekking and survival activities. The medical team has many years’ experience in remote locations. Your safety and well-being is of primary concern and only the most experienced personnel are employed.

The Terms and Conditions of Entry will be supplied when you register your interest in entering the Jungle Marathon. Please contact RunFun Travel for entry information.

Arrival at base camp.
Late morning arrival.
Ensure that you take all your luggage off the boat as it will leave as soon as the last person disembarks.
At base camp, hang you hammock and get yourself settled. There will be plenty of drinking water and hot water to prepare your food. The local villagers often sell fresh coconut water, exotic fruit juices and local food if you prefer not to eat rations whilst in base camp. This is likely to be freshly caught fish with rice.  Make sure you have local reais with you.
After you have had time to have your lunch we will start the kit checks.
Rather than dismantle your hammocks, the support team will come to you so please spread your compulsory kit on the ground below your hammock so they can check it easily.
Once your kit has been checked, take your medical paperwork to the medical team and then go and collect your race number and road book.
