Official event pageWhat this race demands
Challenge Walk MS: Southern California requires athletes to cover 50 miles over three days of continuous endurance walking along the Southern California coastline.
Multi-Day Endurance
Because the event spans three consecutive days over a total distance of 50 miles, participants must possess significant muscular and systemic recovery capacity to perform on successive days.
Extended Time on Feet
Covering this distance entirely on foot demands thorough physical preparation for prolonged impact loading and postural fatigue over multi-hour walking sessions.
A sustained daily walking effort lasting many hours requires consistent exogenous carbohydrate intake, typically targeting 30 to 60 grams per hour to maintain energy levels and prevent late-stage fatigue.
