This year, due to land ownership issues with our usual venue, the race will be held at the beautiful Dinosaur Valley State Park in Glen Rose, Texas. 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.
(Details on how the venue change came about are here... The last two years the race took place at the highest point in the city of Dallas, Prayer Mountain, which is home to the Mountain Creek Church. The church owns the Big Cedar Wilderness Trail, which is maintained by the Dallas Off-Road Bike Association.)
The course is a one-way traffic 16.67-mile loop.
100 Mile: 6x 16.67-mile loops.
50 Mile: 3x 16.67-mile loops.
50K: 2x 16.67-mile loops.
Half Marathon: 1x a shortened 13.1-mile loop.

Mileage is not for contestation. You will cover at least the distance you signed up for.
Here is an elevation profile from data available on Google Earth. This shows the profile for ONE 16.67-mile loop. Therefore, we anticipate the 100 miler will be about 9,600 feet of gain/loss. Click on the picture to see a larger version of the profile.
Here is the elevation profile for the half marathon:
We've been really unlucky two years in a row. The first year, 2014, was a mudfest of constant rain. This resulted in a 20% finish rate in the 100 miler, the 50 miler having to be canceled, and an unusually low finish rate for a 50K.
In 2015, 17 hours into the 100 miler, the entire race had to be cancelled. Storms came through Friday into Friday night, and what wasn't forecasted to happen, they just sat on top of us as we approached midnight. This led to significant flash flooding on the course, which has the highest point in Dallas but also has quite a few valleys and hollows. Runners reported chest deep water. We held the race for an hour to see if the storms would move through and when they didn't and we had more reports of bridges being out and snakes moving out on the trails in the higher elevations to escape drowning, we were forced to cancel all the events.
But third time's a charm! We are hopeful for great weather as castastrophic weather like that is very unusual.
In having to move our venue in 2016 for reasons out of our control, we have chosen a venue that is able to handle rain better than a lot of area trails. However, there are limits that any trail can handle. Because this is a State Park, the park personnel have the right to cancel the race before or during the event if they believe everyone's safety will be in jeopardy. We appreciate they are watching out for us, we understand the tough decision, and we hope the weather isn't extreme so they don't have to make that tough decision!
This is not an exhaustive list but some hazards to watch out for on the trail:
- Snakes - we've had a cold snap recently, so we hope they will have headed to hibernate. There are copperheads spotted in the spring, summer, and fall.
- Bobcats and coyotes - we don't expect them to give anyone any trouble, but they do live in these woods.
- Cactus - Be careful going off trail to use the bathroom.
- River crossings - there are two per race loop, as well as 750 feet along and through a creek that empties into the river. We think it makes this course even more unique and cool. You will get your feet wet in both crossings. In rainy conditions, it may be calf deep. You need to pick your footing carefully on the rock shelves and rocky river floor. Take caution, especially in the middle of the night.
- Slickrock - it's fine unless it rains and then it lives up to its name. Watch your footing.
- Loose rocky terrain
As a state park, they have established a grid of trails through their land. It is each participant's responsibility to watch carefully for course markings. We will be using a combination of
- bright pink contractor tape flagging, with reflective tape on the ends to capture the light of your headlamp in the dark, that will be clothespinned to tree branches and bushes.
- bright pink stake flags for major field sections that don't have bushes to attach ribbons to
- arrow signs (left, right, straight)
In spots where there's an intersection, just follow the flagging for the correct route to take if there are no arrow signs specifically. Flagging will be visible from where you are standing in the intersection.
Confidence flagging: For trail sections where there's no possible logical offshoot of a trail that you could take other than the one you are on, you may go as far as a half mile without flagging.
If you ever get to a spot where you are completely unsure of where you are, backtrack on the path you took until you get to course markers. If you become utterly and completely lost, never ever go off trail. Sit down where you are and wait until someone gets to you.
Ultimately, you are responsible for knowing the course.
