laugavegur trail solo mission

Hello, I am a 24 y/o male who attended the gym 5 days a week, fit, with no health issues.

I am looking to embark on the trail alone from May 20-27. This will be my first time doing something like this. I have hiked through Yellowstone and the grand Tetons and Colorado mountains in snowy conditions, however it was not backpacking.

I would be eternally grateful if someone could fill me in on the details of the trail (ie distance between huts, steep evelation, danger, wildlife), the difficulty of the trail and and essentials that may be missed in backpacking guides on the internet.

Am I unwise for doing this alone as well? It seems it is something I need to complete on my own accord. Any advice or wise words would be very helpful. Please tell me if I’m being an overzealous American or if this is something feasible for me
