Solution

Good start...

tell application "Google Chrome"
    if not (exists window 1) then reopen
    set myBMFolder to bookmark folder "Start My Day" of bookmark folder "My Day" of bookmark folder "Bookmarks Bar"
    set bmURLs to URL of bookmark items of myBMFolder
    repeat with aUrl in bmURLs
        open location aUrl
    end repeat
end tell
