I've seen numerous questions and discussions around how far and how long backpacking with "X' load. This is intended really as an information sharing for those who have paid attention to weight and milage. In reality, there is no right or wrong answers. It really is "hike your own hike" and probably as you hike along .you will go longer and further as long as you don't injure yourself. Here are my general guidelines ... it is not that far off of a lot of working out principles. Also, as note, you can do a lot of distance ..if you need to , but it might not be comfortable and may leave you regretting doing such.
In general I feel the following
- A person can do 3X normal milage with a lightish load for a couple days .. for instance , if you feel ok hiking 7 miles in the mountains in a day you can "probably" do around 20 miles a day in similar terrain for a couple days ....if you start early and don't allow yourself time to get stiff lounging around camp. Unfortunately , much of this recovery and stiffness is probably age dependent. This is not super far off from say working out ..if you can squat X amount you can probably do 3X the reps spread over day for a little bit of time.
- Likewise ... if you can hike "X" amount as a max amount of mileage ..say 20 miles is reasonable ..that is a hard out in the terrain ..you can probably do 50 - 65 percent with a light pack and work up after to the "max" milage in a few days. So ..if you can throw a day pack on and go 20 miles .. reasonable 20 -25 lb backpacking weight is 10 -13 miles and probably working up to near 20 miles per day in 5 -7 days.
Adding more weight ..somewhat depends on how well trained you are. Going to 35 lbs is probably not that big of a deal ..going to 50 lbs is much more of a big deal and that probably requires some training. I hesitate to talk about backpacking and training together ..partially because you should be having fun (of course fun is subjective). However, there is really no way around the fact that our bodies .. can acclimate pretty quickly to conditions. If you don't carry weight ..well it acclimates ..if you do train with weight well ..it acclimates.
Personally .. more weight untrained ..and this is just a wild ass guess ..I'd probably take adding 20 percent of my body weight (35 - 40 lbs) added to say my 25 lb light pack weight (total 65 lbs ) and cut it in half for any sort of duration (5 -6.5 miles) . Of course I "could" do a lot more miles for one day and maybe two .. but to do it day over day the lower milage would probably work fine and then I would work up over 5 - 7 days.
Our bodies are amazing and the acclimate quickly .. but over stressing them can quickly leave you sitting out for a day or two. Anyway, this is really intended as a discussion starting point. I look forward to you sharing your experiences in an effort to help provide guidance to others.
