This is the original marathon from the town of Marathon to the Olympic Stadium in Athens. When you are done, have your picture taken with the Parthenon in the background. For a really special experience, join Apostolos Tours and join a running group lead by Jeff Galloway. He's trained over 170,000 runners and because of his advice I finished the marathon well before I expected and with a nice recovery. Take the full 11 day tour and they'll keep you busy every day with wonderful tours and even a 3-island day trip. They did not scrimp. We all agreed that we had definately gotten our money's worth. Visit apostolostours.com and check it out. You won't be sorry!
