UVU Jungle Marathon – 254Km & 127Km

October 8, 2017 - October 14, 2017

UVU Jungle Marathon - 254K & 127K - Race Connections

UVU Jungle Marathon

Welcome to the 12th edition of Jungle Marathon, an extreme footrace through primary Amazon Jungle in Brazil.

Jungle Marathon, the world’s wildest eco race, gives competitors the opportunity to combine sport and eco tourism and experience this stunning part of the world.

We offer three distances: 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 us from October 5th-14th 2017 in Amazonia, Brazil at the 12th anniversary of the legendary Jungle Marathon .

About Jungle Marathon

Jungle Marathon, the world’s wildest eco-run, organises a 42km marathon, and a 121km or 254km stage foot- race through primary Brazilian Amazon Rainforest in the glorious Tapajos National Forest.

Since its inception in 2003, Jungle Marathon has gained an international reputation as one of the world’s most daunting adventure runs, combining the thrill of the sport with the backdrop of this fragile eco-system.

Runners encounter natural obstacles along the way and are exposed to the realities of the jungle as they encounter jaguar, wild pigs, snakes and a host of spectacular birds and wildlife.

Water crossings full of piranha and caiman increase the excitement.

The organisers work with a 100% local team, providing employment to the 22 small villages that live in this protected area of jungle, and during the racea team of over 200 people provide the safety required in such a potentially hostile environment.

5th October

Boarding the boats. Runners and support staff assemble in the village of Alter do Chao to catch our river-boats to base camp.

There will be jungle marathon staff in the village square from 20.00 hours to assist you and direct you to the boat when it arrives.

The boat will be available for boarding from 21:00 hours.

The boats will depart just before midnight and you are requested to be on the boat by 22.00hrs.

On board

Once you are onboard, hang your hammock and relax for our sail to base camp. You are self-sufficient from the moment you board the boat, so ensure that you have enough food for the pre-race days as well as your race food. There will be bottled water available for drinking on the journey and also hot water for you to prepare your food.

Depending on the boat we charter, there may be soft drinks and snacks available, but please do not plan on this. You can however purchase snacks in Alter do Chao before boarding.

The journey

Journey time is 10-12 hours. The boat will stop once day breaks and drop anchor by one of the many stunning fluvial beaches along the Tapajos River. You will have a chance to swim in the crystal clear waters, often accompanied by river dolphins.

6th October

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.

Our IT team will open for emails this afternoon, so if any of your supporters or family have emailed you these will be printed out and distributed. You will also have the opportunity to send emails.
