The Madrid Marathon is one of 27 races that form part of the Rock n Roll Series, of which 21 are held in the United States and Canada and six in Europe.

"We are all exposed to a barbarity of this kind, which is impossible to predict and difficult to control," added Jimenez, who praised authorizes and medical staff on hand in Boston for their swift reaction.

"A marathon and especially a popular marathon is a sporting celebration. It shows better than anything the effort, hopes and courage of thousands of people who battle themselves to finish the race."

"Sport should serve to unite people and go beyond ideologies and nationalism. More than ever we are with Boston today," said Blanco, who added that the Madrid 2020 candidacy would pay a homage to the Boston victims on April 28.
