Run Against the Tides - Cape Cod's Toughest Ultra. Push your physical and mental capacities to the limit by running against the tides in this grueling solo and self-supported 50-mile ultra. Be back in time to enjoy lobster rolls with your friends and fellow runners at the Sea Meadow Inn in Cape Cod, MA!

The RATT50 Ultra challenge is a true test for the strategic and clever runner. It's not your average David Goggins-style all-out effort; it requires a blend of navigation skills, tactical thinking, and a touch of engineering mindset to conquer the course and potentially break the FKT record.

You'll need to synchronize with the tidal oscillation, navigating five choke points where timing and careful planning are everything. This run demands not only strength but also a strategic approach to effectively tackle the ever-shifting all-sand terrain and use the tides to your advantage.

This route connects the North Atlantic Ocean with Cape Cod Bay, and since both coasts are East and West facing, the Runner is also rewarded with watching an ocean sunrise and sunset on the same day. This route is a true hidden gem that can be used as a weekend training spot for accomplished NYC and Boston ultra-runners and a perfect ultra destination for anyone who dreams of running an ultra solo and unsupported.
