Nestled between the vast green expanses of forests 🌲 and its (very) cool fjord, the capital of this beautiful Nordic country, neighboring Sweden, hosts the new edition of its Oslo Marathon in

mid-September, an event filled with joy and good cheer 😊. The famous 42.195 km race is accompanied by a half-marathon (21 km), a 10 km called the "10 for Grete", and finally a "Mini Oslo Marathon" for our little ones (no pun intended 😆). For the more daring, the "Oslo Triple" allows you to complete all three main distances for a total of 73 km, sure to get your legs moving ! 😱 Also noteworthy is a 10 km race planned for people with disabilities 👨‍🦽‍➡️, a commendable initiative! 👏
