The course is approximately 7 miles long, with the first mile and a half on a paved/gravel country road, and the remaining 5.5 miles on mostly rugged trails, just like it was when Lewis and Clark came through here.  The trail portion is relatively rough but suited for cross-country running.  There are two railroad crossings.  The last ¼ mile of the course encompasses two water crossings.  The first water crossing goes under the railroad bridge (as stated above).  Tie your shoes tight because the mud can be knee deep!  The second water crossing is the Gallatin River.  Be prepared for water up to waist deep at each crossing.  A safety rope will be secured across the river.  Bring an extra change of clothes for the awards ceremony and refreshments.
