On Sunday 24th April the streets of Madrid will be filled with runners participating in the 28th Popular Marathon of Madrid – so bear this in mind if you’re planning to make trips to popular sites – Puerta del Sol, Plaza Mayor and Palacio Real, for example. The event begins at 9.30 am and the starting line is on the Paseo de Recoletos. For more information, take a look at the (poor) official Madrid Marathon website.
