When i did my first one in 2006 i really enjoyed it, i did suffered from the dreaded blisters on both feet and that kind of got me down but after i got home i sat their and told myself wow what have i just done, i went on about it for the next 10 years till i did another in 2016. I can understand the 48% of people would only do one because that is what i sometimes say to myself, ( It wont be the same experience as the first one) how wrong could i be. I can also understand why people want to keep doing it. For me its the people you meet from all walks of life, the stories, the sing songs in the bothys to the peace and quite and the harsh weather you can encounter. Sometimes work and family commitments get in the way but once you have been given the green light you get the TGO fever and thats a great feeling..
