We’re not in the habit of throwing up obstacles, but we make an exception for this obstacle run. What’s more: one of the climbing walls was ‘adopted’ by us, because we just love playgrounds-for-grown-ups. In exchange, Guus, Niels and Frank could climb and clamber, breathe dust and tread mud to their hearts’ content. By their own account, STORMLOOP obstacle run is all about perseverance, improvisation skills and endurance, physical and mental toughness and good cooperation. Sounds like Coreworks.
