Shaded loops through Rome's most beautiful park. Flat gravel paths, Pincio Terrace views over Piazza del Popolo, and the Galleria Borghese at the north end.

From the Colosseum along Via dei Fori Imperiali, past the Circus Maximus, down to the Tiber, and back along the river. Ancient Rome at dawn.

Head south on the ancient Appian Way — original Roman cobblestones, umbrella pines, and aqueduct ruins. One of the most historic runs in the world.
