We’ve added an extra challenge to our SoJo Race Series - Rucking! 

About Rucking

Rucking is simply walking with a weighted rucksack or backpack. You wear a backpack or rucksack, add weight, walk, it’s a fitness thing. And you’re already doing it. It implies action, energy, and purpose. Rucking requires strength, endurance, character and builds it too. Hiking is rucking in the mountains and urban hiking is simply called rucking.


Rucking provides cardio that burns up to three times as many calories as walking. The weight adds resistance training to your back, shoulders, your glutes, and legs with every step - resulting in strength gains in your muscles. Rucking exercises can be done at any weight. Start small (5 to 10 pounds) and work your way up. Want more? Up the weight, increase the distance, or go faster. You get to decide.


Register today for the SoJo Race Series Ruck Challenge. This 10-week challenge will test you every week with a new route. Set the distance and decide the weight and speed. Complete challenges and win challenge-specific patches for your backpack. Earn bonus miles by completing DIY rucks in the mountains or in your neighborhood. In addition to winning patches from challenges, every participant will receive a swag bag and prize.

Sign up and get up to 3 patches, plus you can choose to get the Ruck Challenge shirts. Check out our Gold Rush Ruck Challenge shirt.
