The box. Hot-foiled on the front and down the spine. Each of the four guardians gets its own colour.

The certificate. Issued in the app the moment it records your finish, in Turtle's own colours, with 68 km on it. Shown blank here. Your details are written onto it when you finish.
The turtle is the only one of the four you could actually meet — and that is the point. It is the sacred creature made of ordinary, unglamorous endurance. In East Asian myth the turtle is what you trust to carry something for a very long time: it holds the world up, it outlives the dynasties built on top of it, and it has never once needed to hurry.
The reverse sets a gold ingot on the crest of the waves — wealth the sea does not take back, because the turtle is underneath it. Sixty-eight kilometres in thirty-nine days will not feel dramatic on any single day, and the thirty-nine is chosen: the lesser of the two lucky numbers for wealth, the quiet one. Six weeks later it will be the reason the number moved.
Finished on both sides. Neither face is a stamp of the other.


Every guardian is given a ribbon dyed to the enamel it carries: pine green for the turtle. This is the exact weave, at full width.

Pine green, matched to the turtle's enamel.
A gold key-fret runs the full length of both edges. The same border is on all four ribbons; only the ground changes.
A tone-on-tone weave, visible when the light catches it and quiet when it does not.
Printed the same front and back, so it reads the same whichever way the medal hangs.
