    Re: What constitutes Round The World (RTW) ?
    From: Bill Lionheart

    So at first I thought that was a strange definition, passing through
    antipodes. But then I thought of some closed path (ie the track of a
    journey that starts and finishes in the same place). Now consider the
    path of the antipodes.  The criteria is simply that these two paths
    must intersect.  It is certainly much easier to explain than mine and
    nice and easy to check.  I wonder if navigators circumnavigating by
    these rules celebrate the first time they cross the antipode of their
    path?
