A loaf of Runnin’ Bread (possibly a corruption of Run-in Bread) appears to be a typical loaf of a mundane bread (e.g. white, wheat, sourdough, rye, etc. – though white is the most common variant). Although typically found in loaf form, up to a dozen of the first slices of the bread (1d12) will carry its enchantment.

When the loaf or one of its enchanted slices is held by the mouth, the character (and their party) are empowered to run at twice their normal movement rate; however during this movement their chance of random encounters and of being and inflicting surprise are also doubled. If the mouth-borne bread was toasted first these values are instead trebled.
