Duo Marathon

An accessible and friendly relay format

Combining a sporting challenge and a fun event, the Duo Marathon is a very popular and accessible format which enables two runners to complete the Marathon route in relay. The race will take place on Sunday 27th May 2018.

If you are the first runner in your relay team, you will get off to an unforgettable start, crossing the line with 4,000 other marathon runners. You will then hand over to your team mate in Cherrueix at the 20.5k mark, where you will receive your medal, a T-shirt and refreshments. You can then go to the finish line either using the free shuttle buses which will be running from near the handover area or make your own way there.

If you are the second runner in your relay team, you will finish opposite Mont Saint-Michel, buyed by the thousands of spectators who line the last few kilometres. Free shuttle buses will take you to Cherrueix from the start in Cancale on the Sunday morning. There will be a left luggage area for your bags at the relay zone.
