Travelog is formed from "travel" (from Old French *travailler*, meaning to work or toil) and "-log" (from Greek *logos*, meaning word or discourse). The word "travelog" refers to a narrative or account of one's travels, essentially a discourse about the work or experiences encountered while traveling.
Think of 'travel' as the experiences you have while 'toiling' or working through your journey, and '-log' as a word or account of those experiences.
