 Old school friend of mine did a 4 year man-powered adventure

Epic isn't it!

 And he did it wearing 1980s era shoes 

 What shoes or sneakers he were wearing? I want those. 

 Forest Gump would proud of that achievement 🧡 

 ha sweet... i've done a few thousand km walks over the years, but 15k miles is epic

i found after about 400km you really need to rest tho
