A great area for running in Athens. Combine the pedestrian-only streets that line the base of the Acropolis, and then head up the hill. Can be combined with Philopappou Hill, which has 2-3 miles of paths.
The stadium dates back to the 4th century BC and was the site of the first 'modern' Olympic Games in 1896. It's a treat to run on the dirt track inside the stadium, or up and down the marble stairs. Across from National Gardens.
Tour the site of the 2004 Olympic Games! Combination of perimeter road around the complex, and some interior paths. See the Olympic stadium, Velodrome, Aquatic Center. Area is 10km northeast of Athens. Video Excerpts!
A great tour of Boston's Back Bay. Includes the Commonwealth Ave. Mall, Public Garden, State House, and a jaunt along the river. Captures so much of Boston in one run!
