Hi,

one thing I figured out and thought worth to share.
To have a gain of 800 to 1000 height meters means for me, in my region, 6-8 times going up with weight and down with out (to keep my knees healthy). BUT HOW TO GET NEW WEIGHT IN REPETITIONS? HOW TO BE MOST TIME EFFECTIVE?

I now use a carrying tool (“hook a bike” – I do not have any commercial interests!) for my most heavy MTB (15kg) on a backpack filled (1.8kg) with 4L water-weight. Such I go up by (18-23% steep) carrying all for around 20min and quickly down (2min) using my bike – the only issue is to have a trail not being too small due to the MTB carry (~1.5m width)
