Course Details
We don't have the course available on Strava. A GPS watch won't stay accurately connected to satellites in the tunnels and will give inaccurate estimates of elevation changes and distance. The Athlete Guide has very detailed course descriptions for both the Half Marathon and 4 Mile, including:
- Step by step descriptions of elevation changes
- Elevation chart
- Descriptions of the tunnels and views
- Course marking signs
- Aid Station Chart
The course has rolling hills, but nothing steep or intimidating. On the way out, many runners say it feels almost flat until they notice they’ve been gradually climbing. The rises are gentle and blend into the terrain, so you’re never facing anything that feels dramatic. The bonus: the return trip has more downhill, and that’s when you really see how subtle the climb was on the way out.
For both distances, expect occasional broken or uneven pavement, especially inside the dark tunnels where visibility is lower. We clean the tunnels thoroughly before race day, but we encourage all participants to stay alert and watch their footing.
