On their website, the Haspa Marathon Hamburg organisers express their deep compassion with the families of the victims and the injured runners and spectators in Boston. It is a sad day for the sports and for all marathon runners, they write.
Furthermore, they assure that they are in close dialogue with the City authorities to check and if necessary adjust the security concept for the upcoming event. The marathon will take place at the planned date, Sunday 21 of April.
