Big Cedar Endurance Run was the first 100 mile trailrunning event in North Texas! In our 4th year, we have moved venues and renamed the race the Dinosaur Valley Endurance Run!

This course has rolling and sustained ascents and descents, although none are terribly steep. The loops take you through varied terrain, from double track trails in fields to single track in wooded areas. There is a mix of packed dirt, smaller rocks, larger rocks, slick rock, and some roots. There are also two river crossings per race loop. This course really has a little of everything, which includes its views. There are amazing overlooks on this course where you can see for miles.


The course is a one-way traffic 16.67-mile loop.
100 Mile: 6 x 16.67-mile loops.
100K: 4 x 16.67-mile loops.
50K: 2 x 16.67-mile loops.
Half Marathon: 1 x a shortened 13.1-mile loop.

Local time: 8:26 AM
