In this paper we focus on the Lebesgue property of Banach spaces. A real Banach space X is said to have the Lebesgue property if any Riemann integrable function from [0, 1] into X is continuous almost everywhere on [0, 1]. We obtain a partial characterization of the Lebesgue property, showing that it has connections with the asymptotic geometry of the space involved.
