I consider myself a medium-lightweight hiker.
(no selfmade gear yet, but expensive lightweight gear, no double gear, no spare clothes)
I did an adventure walk based on Ryan's journey's (based on the calory diet calculation) in Tasmania:
49 kg (over 100 lbs) at the start but i walked for 47 days climbing 19 mountains, covering about 800miles maybe more.
i did not have many sponsors or time to built gear as i prepared everything in 1 month !!!
