Hike Difficulty Calculator
I found this formula for rating the difficulty of hikes one day while surfing through Mike's Hikes and thought it would make a useful calculator. Of course these ratings are only an indicator of hike difficulty - every hike has its variables beyond elevation gain and distance including weather, experience/fitness, unique trail conditions, starting/ending elevation, etc.
These equations do not represent the
true difficulties for very short and steep hikes.
According to Mikes Hikes, allow 1 hour for each 1,000 feet of elevation gain, and another hour for every two miles of distance. I would have to agree with Mike when he says "I´ve always found myself hiking faster than this, though."
The equation for novice mode comes from the book Rocky Mountain National Park Dayhiker´s Guide by Jerome Malitz and was developed by Dick Holley.
Rating (Novice) = ( 0.002 x elevation gain [ in feet ] ) + round trip distance [ in miles ]
The equation for expert mode is continuously being modified by Steve thanks to comments received regarding calibration of the constants with respect to difficulty.
Rating (Expert) = ( 0.0005 x elevation gain [ in feet ] ) + round trip distance / 2 [ in miles ]
