TRIBU
nature challenge
a wild obstacle course race
unlike anything
you’ve ever experienced
Three days living, training, and racing
in the mountains of Basque Country
First Edition : May 2-4, 2025
Day 1
-
Fly or drive in to Bilbao, join us onsite anywhere from 10am-4pm, set up camp, make yourself comfortable.
-
Together we explore the terrain, set up the various challenges we’ll be facing, and start acclimatizing to our surroundings.
-
Gather round the fire, share good food, and enjoy the music.
Day 2
-
We fine-tune our challenges, learn how to move through them safely, and gently test our readiness in a variety of contexts.
-
We will challenge ourselves in a variety of contexts that test our physical and mental capacities, for both collaboration and competition.
-
Gather round the fire, share good food, enjoy the music, let loose a bit more.
Day 3
-
Run, jump, climb, crawl, lift, and move your way through a series of natural obstacles designed to test the full range of your physical capacities. We all start together, and go as long as we can last:
60 minutes for those who are starting out in primal movement and want to push themselves, within reason. 3km + challenges.
2 hours for those who want to go further and faster, and test the full range of their capabilities. 6km + challenges.
4 hours for those who are ready to test not only their strength and ability, but also their physical endurance and mental fortitude. 12km + challenges.
-
Eat good food, rest, and recover with sauna, ice baths, massage, and more.
-
We’ll close things out with a small celebration and start making our way back home at 4pm.
INDIVIDUAL
adventure,
TRIBAL
challenge
As a society we’ve allowed ourselves to become too specialized in our training, and too isolated in our lives. We’ve forgotten our innate drive to move freely, feel deeply, and immerse ourselves in nature.
Tribu is your opportunity to change all of that.
REWILD YOUR
BODY,
FREE YOUR
MIND
-
Camping, bonfires, and sharing both the joys and challenges of primal living.
-
We’ve designed the challenges to cover the full range of our evolutionary movement patterns, from crawling to climbing to running, lifting to jumping, strength to stamina.
-
There will be challenges and competition, but there will also be plenty of opportunity for collaboration, sharing, and just having a good time.
Families and kids are welcome.
