The Throwline Event tests the contestant’s ability to install a climbing line into a tree using a throwbag and throwline. In this event eight (8) branch unions are designated as targets, representing different climbing points in the tree that would be suitable as a tie-in point. Their suitability is based on the tie-in point’s location in the tree and capacity to hold the weight of the climber. The contestant must accurately place two lines in the tree within the 6-minutes allotted. Two distinct sets of four targets (making a total of eight possible target options) are set in the tree. The contestant must choose one target from each side of the tree, making for a total of two possible lines set. Judges only score a throw if it is in the target area and both ends of the throwline are isolated, meaning they are hanging parallel and touching the ground. Additional points may be earned for installing a climbing line through one target on each side of the tree.
The Throwline event is worth up to 30 points.
