The Superior Street construction project is causing a temporarily modified race course for runners of Grandma's Marathon and the Garry Bjorklund Half Marathon.

Both Grandma's Marathon and the Garry Bjorklund Half Marathon have historically followed the same course, running along the Lake Superior shoreline and then through downtown Duluth before finishing in Canal Park.

The majority of the course will stay the same, with the rerouting taking place during Mile 11 of the half marathon and Mile 24 of the marathon.

According to Grandma's Marathon:

As race participants make their way through downtown Duluth, they will continue along Superior Street until they cross 4th Avenue East. They will then make a left turn off of Superior Street and proceed down to Michigan Street where they will have the opportunity to experience a unique section of downtown for the subsequent nine blocks. Participants will travel west on Michigan Street until they reach 5th Avenue West near the Mile 25 mark to reconnect with the original course that guides them to the iconic finish line.

The reroute will be in effect for the 2018-2020 race seasons and is contingent on the phases of the City of Duluth’s reconstruction plan.

The course has been measured and certified by USA Track and Field, and the modification has virtually no impact on the start or finish line locations. The Mile 25 aid station will be located near the corner of 5th Avenue West and Michigan Street.

Keep in mind that spectators will have have limited access to the rerouted section of the course along Michigan Street and it is recommended to plan out viewing strategies in advance to accommodate the change.

Below is a map indication the temporary course modification.
