Jelle Guldenaar | 100 Cols Tour
Jelle cycled the “100 Cols Tour”, the ultimate challenge for the experienced cyclist and perhaps the toughest tour in the world: over 4,000 kilometres, 100+ cols and a staggering 70,000+ altitude metres! The start and finish of this tour is in Obernai, near Strasbourg in the French Vosges Mountains. At least, that's the closest starting point from the Netherlands and Belgium.
