Prior to the event, the judge will measure the diameter of the log. The competitors will indicate the areas to be chopped.
No team members may assist in supporting the cant. Chains, spikes or stanchions may be used.
Upon completion of the first competitor's chop the second competitor may begin. Each competitor may turn once during the chop. Should the second competitor begin chopping before the first competitor has completed, disqualification will result.
Total time is taken from the GO signal until the completion of the second cut.
All chopping must occur between footholds. A thirty second penalty will be issued should a competitor cut into footholds.
Once the first competitor has completed his/her cut, he/she may not restart chopping. Disqualification will result if this takes place.
Upon inspection by the judge, if an incomplete cut is found, a thirty (30) second penalty will be issued.
Should a competitor be caught kicking apart the few remaining threads of an unfinished cut or completing a cut in any other manner, a disqualification will result.
Should a competitor fall off the log and then strike it with his/her axe, a thirty (30) second penalty will result.
A maximum five (5) minute time limit will be allotted per competitor. Any team reaching this time will be awarded points based on a percentage of the winning time.
