Course information

The 26.2 mile course blends points of interest within the City of Thunder Bay with the natural beauty of Lake Superior.  The course combines urban, park, and residential settings into a unique experience for the race participants – along with many opportunities for spectators to see their favorite athletes. Miles with the Giant 2015 is a Boston qualifier.

Full marathon participants will enjoy the best that Thunder Bay has to offer in both the South and North of the city.  Their route will take them south first, through the Lakehead University and Confederation College campuses to Chapples Park/Golf Course before turning North on Balmoral Street where they will retrace their steps through the campuses before joining  half marathon, 10K and 5K participants on the north section of the course.

The north course section around Boulevard Lake Park and Centennial Park includes tranquil forested areas, beautiful lake views, and terrain to challenge all levels of participants.  Runners will also be treated to a spectacular view of the Sleeping Giant on their sprint to the finish in the Festival Area of Prince Arthur's Landing.

The course elevation profile is available here.

Half marathon participants run the complete North Course (turning right at Park Ave & Court Street)

10K participants follow the North Course (turning right at Park Ave & Court Street) to Boulevard Lake where they turn around and retrace their steps back to Prince Arthur's Landing.  Watch for the Red 10K turn-around flag!


Participants in the marathon and half-marathon will receive finisher medals upon crossing the finish line.   Participants in the 10K will receive a finisher's ribbon upon crossing the finish line.

All marathon participants must be able to finish the event in six hours.  The city permits issued to the Thunder Bay Marathon-Miles with the Giant do not allow the roads to remain closed beyond this time limit - participants must cross the finish line by 2:00pm in order to be considered “official finishers”. This means maintaining an average pace of 13:44 minute per mile.  The race course will be opened to traffic on a rolling schedule as participants make their way to the finish.  In order to ensure safety, participants who reach the 35 km mark after 1:00pm will be required to withdraw.
