The San Luis Obispo Marathon + Half IS A BOSTON QUALIFIER. The staff is happy to announce that its marathon and half marathon courses have been officially certified by USA Track & Field, thus making the San Luis Obispo Marathon a Boston Marathon qualifying event. The event is exceeding its projected registration numbers and the race staff has decided to cap the marathon and half to ensure each participant receives their promised medal and race shirt, as well as a quality experience in the Inaugural running. Registration is filling fast and officials expect the races on Sunday, April 22 to sell out. There is plenty of space in the 5K race that takes place on Saturday, April 21.
