How fit do you need to be to hike the Gubeikou section of the wall

Jinshanling is more energy consuming compared with Gubeikou and it takes about 1.5-4 hours based on different hiking routes. Gubeikou is no much difference in time consuming. So 2 seperate days are enough for these two sites. As for how slow you can hike along them, it depends on your chosen route; if you are going to hike for a short section, you can hike slowly. Have fun~
