Just a little while to go and the Batavierenrace starts again. Experienced runner or beginner, what is the best way to train? Does running wear out your knees? Are good shoes important to prevent injuries? When does the runner's high occur? Does beetroot juice make you run faster? How do you motivate yourself in pouring rain? Science journalist and running coach Mariska van Sprundel MSc combines scientific insights with practical experience. She writes for Runner's World, makes blogs and books, such as Alles wat je wilt weten over hardlopen and Missie Marathon. In cooperation with the Bata Committee and Aloha.
