Course notes for 2021, Ft. Stockton to Sanderson and return.

* Please note that these course notes are based on the 2017 race.

You will notice that there are no mileage markers listed on our course notes. When we did the survey, the mileage markers were being re-done as part of the continued maintenance on U.S. 285. There is a real possibility that they won’t be in place until after the race. It is highly recommended that you do your own survey and note reference markers that work for you.

Please remember that the Big Bend Open Road Race is called “One of the Most Exciting Open Road Races In the World” for a reason. In the last 50 miles leading to Sanderson there are 59 turns, some blind, a great many elevation changes, and two lanes that turn into four lanes that turn back into two lanes. These are Texas roads – wide and smooth with wide shoulders. There is an old saying in open road racing, “keep it between the white lines”. Good advice.

Enjoy!
