The Roman Geira, a roman path built in the year 75ad connected Bracara Augusta to Asturica Augusta in Spain.The Roman mile (mille passus, lit. "thousand-pace"; abbr. m.p.; also mille passuum[n 2] and mille) consisted of a thousand paces of two steps each. The ancient Romans, marching their armies through uncharted territory, would often push a carved stick in the ground after each 1000 paces. Well fed and harshly driven Roman legionaries in good weather thus created longer miles. (Wikipedia)
