Did You Know?
The most popular route of the Camino de Santiago, a pilgrimage walked for over a thousand years, is nearly 500 miles and usually takes about a month on foot, a tradition that predates GPS, cushioned sneakers, and the modern mile itself.
Stride length naturally shortens with age, along with more time spent with both feet on the ground at once. Researchers sometimes use gait speed alone as a simple, low-cost marker of overall health in older adults.
