Apologies from the Editor of Beside The Creek.
I have never heard of this practice until to-day.

The Christus Rex Pilgrimage is a 3 day walk from Ballarat to Bendigo,covering over 90 kilometres. This route takes us from one great cathedral – St. Patricks, Ballarat – to another splendid cathedral – Sacred Heart, Bendigo. Over the 3 days we walk through the picturesque and serene countryside and forests of Victoria, through the towns of Creswick, Smeaton, Newstead and Lockwood. Along the route we engage in prayers and song – rosaries, litanies, hymns and medieval pilgrim songs that unite all in fellowship. Daily Mass in the extraordinary form (1962) is celebrated every day in local churches, except on the Saturday where Solemn Mass is celebrated in the woodlands of Campbelltown at a woodlands site; sacred polyphony and Gregorian chant are a part of each Mass. There are many opportunities for confession and spiritual guidance from the priests who join us on the pilgrimage.
