The River Running, called Celduin by the Elves, is a river in Rhovanion.

The river originates beneath Erebor (The Lonely Mountain) and flows south to the Sea of Rhûn. Carnen and the Forest River out of Mirkwood are tributaries of the River Running.

The River Running is a 600–Númenórean mile long river that runs from the Lonely Mountain south through the Long Lake, where it is joined by the Forest River, and thence through the eastern outskirts of Mirkwood, then south east through apparently uninhabited regions of Rhovanion to its confluence with the Carnen and finally in a long south-eastward loop to the great inland Sea of Rhûn, past the land of Dorwinion.
