Suffer from too-tight boots or traverse-induced thigh burn? Moles’ feet carried in a pocket are said to be a charm against cramp. It’s the wackiest cramp cure we’ve heard and comes from What’s What, the Encyclopedia of Pointless Information (£9.99, Metro). Apparently moles’ forefeet are said to cure aching arms while the hind feet are supposed to be good for painful legs.

If you’re after a little less freaky solution, stash a can of V8 vegetable juice in your pack and drink it when cramp comes on. The juice will rehydrate you and the sodium and potassium contained inside will replace lost salt and minerals, a loss of which may exacerbate cramp.
