Note regarding 15K and 5K courses and preview videos:
The start line is moving down the hill you see in the first few seconds of the video. Because of this, a short out-and-back section of trail will be added to the 15K (not shown in the video). We may reroute another short part of the 15K too, but it's a very small section.
The start line change's impact on the 5K is that it shortens the course to 3.1 miles, making it an actual 5K (vs the 3.3M that is was)! You'll thank us later.
