According to Google map it would take approx 15 days, depending on how many miles a day you walk. Google has directions too. Are you walking for a charity or for the heck of it? Good luck to you either way!!
As Zoya mentions, Google can estimate travel time by walking. However, it probably doesn t take into account rest time, sleep, etc. 2.6 miles/hour is a good estimate.. unless of course you re on a roadway w/no sidewalk or shoulder. Considering food, shelter, and sanitary needs, it would likely be less expensive to fly.
