Gym

Difficulty (D) # Name Specs Notes
2 Easy to Moderate Activity at official gym facility




Hike

Hikes are rated on a grid according to distance and elevation gain. Additional considerations include: Hikes posted that include any of the additional considerations listed above may be rated at a higher difficulty level than just the distance and elevation would indicate. No hikes involving a river ford are allowed.

Note: Hover your mouse over the D links in the chart to see examples of which hikes fall into this category. For the examples given, elevation gains were based on actual measurements, rather than on net elevation gains provided by many guide books. They are also rated according to our "actual" end point on typical events rather than just to the end of an official trail (which is frequently all that is provided in the guide books).

Hike Distance

Hike - Backpack

Backpack event difficulty ratings apply only to hike+camp events. Backpacking in general carries risks similar to hiking but on the more advanced trips, route finding, difficult creek crossing and sanitation skills may be required. Overnight events for other activities (e.g., snow shoeing, backcountry skiing, cross-country skiing, biking, boating) are covered under those activities.
Difficulty (D) # Name Specs Notes
3 Moderate Maximum D2 Hike with pack to "base camp" with hub-and-spoke day hikes returning to "base camp" on well-marked, signed, maintained trails with maintained campsite. Not remote - access to roads/assistance less than one day.

Suitable for beginner backpackers.
Example: Hike to Elbow Lake campground as "base camp", hike to The Forks campground as "base camp".
4 Moderate to Difficult Maximum D3 Hike packing each day for a max of three days OR D3 Hike to "base camp" with hub-and-spoke day hikes on well-marked, signed, maintained trails with maintained campsite(s). May involve simple creek crossings. Easy access to water and accessible exit points. Not remote - access to roads/assistance less than one day.

Suitable for beginner backpackers who are strong, experienced hikers.
Example: Tombstone (because of creek crossings), Ribbon Lake from Buller Pass.
5 Difficult Maximum D4 Hike packing each day for a max of five days. Hiking on maintained trails and camping at maintained campsite. Trip may involve a one-way route with vehicle shuttle.

Not remote - access to roads/assistance less than one day.

For the examples given, elevation gains were based on actual measurements, rather than on net elevation gains provided by many guide books. They are also rated according to our "actual" end point on typical events rather than just to the end of an official trail (which is frequently all that is provided in the guide books).
