Coming May 5, 2013. Starting in Brittany and finishing in Normandy, the 16th annual Mont Saint-Michel Bay Marathon is one of the few marathons where you can actually see the finish line from the start. It typically welcomes 5,000 runners from all over world, and is one of the few runs on an iconic UNESCO world heritage site. In the days leading up to the marathon there will also be a 10K race in nearby Saint Malo as well as other activities. By the way, you can also run the marathon as a 2 person relay team.
