→‎Distances, Ascents, Descents and Walking Times
This trail description contains plenty of numbers for distances, altitudes, ascents, descents and even walking times. All these numbers are based on the "cleaned" GPS track without our occasional seek and search detours. Also all altitudes, ascents and descents are based on a digital map with a quite precise altitude profile.
These numbers are therefore also free of accumulated "GPS noise" and "barometric altimeter noise" that increase the measured distances, ascents and descents when recording the track by GPS while hiking. So, don't be surprised if your GPS will always indicate longer distances, more ascents and descents even if you stay on the trail. A deviation of 10% is typical.

So, don't be surprised if your GPS will always indicate longer distances, more ascents and decents even if you stay on the trail. A deviation of 10% is typical.  The walking times provided here are estimated moving times without any breaks and rests. When evalutating evaluating our GPS records I was surprised that we did not move nearly one third of the time between leaving the camp in the morning and stopping again in the evening. It did not appear to us that we make such long breaks but the GPS record does not lie. So a walking time of 6 hours means more or less a 9 hour hiking day adding normal breaks for eating, taking pictures, verifying the route, chating with the locals on the trail or harvesting some piñones. 
The estimated walking time is calculated purely based on distances, ascents and descents. I opted to use such a calculation because it removes the unnecessary seek and search detours and the factor of having a good day or a bad day. I developed and verified this calculation method based on all our GPS records and was surprised myself that such a simplified calculation provides quite reliable estimates. The calculated times correspond closely with our actual walking time. If applied to our actual GPS records the average deviation per day is 15 minutes and never more than 50 minutes.
These factors resulted in the smallest average deviation to our actual moving time recorded by GPS. I'm would not consider us as fast hikers , therefore the Walking Times walking times calculated with based on out hiking speed are rather conservative.

The altitude profiles for each section were constructed keeping the same scale, as follows:
