Consider a one week trip in nature, with bikes. Daily routes are to be about 60km with 2000m total elevation change per day (climb, then descend). The group is of 2-5 people. Weather is summer (maybe down to 5 centigrade at night, not sure about rain).
My question is how can we pack smart, so that we can sleep on the trail.
For the bike a multi-tool, tube patches, 1 extra tube, quicklink, pump and chain lube. Anything else?
For food: about 3.5kg of food per rider, or half of that if we pass through mountain huts. Options.
Now, the real question is about sleeping gear. Sleeping bags are bulky and heavy. Here probably the smart move is to get a summer down bag. But what about the sleeping mat? Those are light but very bulky. I am afraid that tying one of the standard foam ones to the backpack will not only create air drag on the descents, but will also catch on vegetation adjacent to the trail. Unfortunately, they are also quite essential.
Any ideas how can we pull this off? How do we carry functional sleeping equipment and still not be too encumbered to ride?
