 |
DISCONTINUOUS A journey broken across multiple legs, expeditions or detached seasons. Not continuous. A discontinuous journey is Supported. See also Continuous |
DISTANCES Calculation and recording A journey’s distance pre-expedition should be calculated from start to end and include major Path deviations. Standard routes such as Hercules Inlet to South Pole, Ward Hunt Island to North Pole and Point 660 to Isortoq coast across Greenland have recognised distances that should be used when promoting and immortalising journeys. Slight variants in these distances are acceptable. PECS’s standardised method of recording total distance is the tallying of camp location intervals, including start and end points. In addition journeys can record finer waypoint intervals eg. 30 minutes, however the camp to camp tally will be the accepted distance. Round-trips to retrieve a second sled or load should not be included in the tally. Journeys on the Arctic Ocean should record straight line distance and a camp to camp tally that will take into consideration overnight drift. |
DISTINCTION An Unsupported journey that has achieved a first gender, first route, first mode of travel or first unsupported. A Distinction may also be awarded at the discretion of the PECS Committee. |

GUIDED A guided journey is one that uses a guide or guides to manage and lead a team while the journey is underway. Guides often plan unique and committing journeys for their clients and as such a Guided journey is not classified as Supported unless it falls within Supported definitions.

A journey’s distance pre-expedition should be calculated from start to end and include major Path deviations.
Standard routes such as Hercules Inlet to South Pole, Ward Hunt Island to North Pole and Point 660 to Isortoq coast across Greenland have recognised distances that should be used when promoting and immortalising journeys. Slight variants in these distances are acceptable.
PECS’s standardised method of recording total distance is the tallying of camp location intervals, including start and end points. In addition journeys can record finer waypoint intervals eg. 30 minutes, however the camp to camp tally will be the accepted distance.
Round-trips to retrieve a second sled or load should not be included in the tally.
Journeys on the Arctic Ocean should record straight line distance and a camp to camp tally that will take into consideration overnight drift.
