Description: The BASQUE ULTRA TRAIL SERIES Circuit is a set of four ultra-distance and semi-self-reliance mountain races that links the three Basque and Navarre capitals throughout a year along mountain routes. The four stages/races will have a length of between 110 and 140 kilometers each and add up to 500 kilometers. The races will take place every two months, approximately, to give participants time to recover physically and be able to complete the challenge of linking the four cities in a single year.nnn
