Each article answers one question about heart rate, thresholds and recovery: what the number means and what you can do with it.

How do you train for the Vierdaagse or a multi-day hike?

Four consecutive days of 30, 40 or 50 km are something other than one long hike. Your fitness is not the limit; your feet and tendons are, and they have to carry the days that follow one another. Eating on the way and the July heat come on top of that, and you need to practise all three beforehand.
