The course is open for running any time with the exception on the winter, when it is groomed for cross country skiing.
The Birkie Trail Run Half Marathon course starts and finishes on a 1.5 mile out-and-back on the Birkie Ridge Spur Trail with a single counter clockwise loop in the middle. The heart of the loop is on the Birkie Trail which is a wide and grass-covered trail built for cross country skiing. The profile is famous for its relentless terrain changes. The ups and downs, though relatively short in height difference, are steep, many in excess of 20%. There are no huge, mountainous climbs, but the many small steep climbs add up to a lot of vertical. There is a three mile section of singletrack which features a dirt surface that is relatively smooth with occasional stones and roots. This section includes the second longest climb on the course, but it is significantly less steep than the climbs on the Birkie Ridge Trail
and Birkie Trail.
