What is rucking?
Rucking is a physical activity that involves walking or hiking with a weighted backpack (called a rucksack). The term comes from the military, where soldiers train and operate carrying heavy loads over long distances. In civilian fitness and recreation, rucking is gaining popularity as a versatile and low-impact workout. We now offer it at all Chilly Willy Events!
More information about rucking.
Although the Ruck Divisions are timed, it’s not competitive, and there are no age group awards. However, ruckers will still receive a finisher woodle!
