Five kilometres has never seemed so epic. Join the world's largest running series in a muddy obstacle course that will test your endurance and push you to your limits, as the Warrior Dash makes its Japan debut at Sagamiko Resort this month. Throw on your fluffy warrior helmet and battle your way through a course featuring 15 natural and man-made obstacles, then unwind with a stein of beer while listening to DJs including Ken Ishii (Saturday only). Race start times are staggered at thirty-minute intervals throughout the day, with up to 500 intrepid runners departing at each time. If you just want to go and soak up the atmosphere, opt for a ¥1,000 ‘festival attendee’ ticket.
