Don’t scrimp on sunscreen.
Basal cell carcinoma, a form of skin cancer, is more common in people who spend long periods outdoors, such as runners. (The risk is 43 per cent higher among outdoor workers.) You will need a teaspoon’s worth of sunscreen per limb, according to sun-protection and skin-cancerprevention experts Sunsmart. Put it on before donning your kit to avoid missing bits, and allow time for it to be absorbed.
