Cape Cod Marathon Weekend
presented by Shipwrecked 
The Cape Cod Marathon Weekend is produced by the Falmouth Running Club, a non-profit running club. Race weekend includes a Marathon, a Marathon Relay, a Half Marathon, as well as a 5k! The Clam Chowdah Challenge is for those who would like to tackle both the Marathon and the Half Marathon in the same weekend for a total of 39.3 miles. The Lobstah Challenge is a fun event for those that want to run the Half Marathon and the 5k in the same weekend! Staged in early October at the start of fall foliage, these gorgeous courses run along Vineyard Sound and along beautiful coastal roads on the Cape. Please note: our courses are OPEN to traffic but are well monitored by police, flaggers and volunteers.
The Cape Cod Marathon Weekend does not allow, support or encourage the buying, selling or trading of bib numbers for any of our races, for any reason. Running with someone else's name & information or as a Bandit causes chaos and can be potentially dangerous in the event of a medical emergency.
