““The Last Hundred Kilometers Once you get to Rome, you will probably want to receive a testimonium, a certificate of completion of the pilgrimage. To get a testimonium, you must prove you have walked or cycled the required distance. Your proof is your credenziali or Pilgrim Passport that has been stamped at each of the places you have stayed. The Opera Romana Pellegrinaggi (ORP) offers testimonia to pilgrims who have walked at least the last 100 kilometers from Montefiascone. If you prefer to receive a testimonium from the Vatican, you must either walk the last 140 kilometers from Acquapendente or cycle the distance from Lucca to Rome, over 400 kilometers.””
