Welcome to Calgary\'s first and Canada\'s largest urban adventure race. With the help of our local orienteering club and association, Inner Limits was formed to promote the sports of orienteering and adventure racing to competitors of all levels. Entering its 5th year in 2006, Inner Limits has given over 600 competitors an experience they will not soon forget. Racers cover a distance of 100 kilometers in an adrenaline filled 12 hours of paddling, orienteering, mountain biking, in-line skating \'urbaneering\', and mystery challenges as they push their \"Inner Limit\" to reach the finish line .
