Ultramarathon events and ultramarathon calendar

Ultramarathon Calendar, ultramarathon race listings, ultramarathon events. Ultra runners are lacking a comprehensive source of information about worldwide events, and we hope to change that. This site is certainly not just a 'list' of worlwide ultras. It contains facts, figures and statistics which will help you decide which race is right for you. If you are new to the sport it is the perfect place to find information.
