Should you ever have the opportunity to visit ancient Corinth, there is an out-of-the way, seldom-seen-by-tourists place that makes what Paul wrote to the Corinthians more meaningful.  Remember Paul's comments that those who run in a race should run in such a way as to gain the prize?   If your guide really knows his geography, he will take you to the place near the Corinthian canal where the Isthmian games were held every two years.
