Calgary\'s first and Canada\'s largest urban adventure race. With the help of the 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 6th year in 2007, Inner Limits has given over 600 competitors an experience they will not soon forget. Racers cover an approximate distance of 80 kilometers in an adrenaline filled 12 hours of paddling, orienteering, mountain biking, geocaching, \'urbaneering\', and other mystery challenges as they push their \"Inner Limits\" to reach the finish line.
