The Lone Star 100 is a rugged, unforgiving mountain race located in the Southernmost tip of the Rocky Mountains in El Paso, Texas. This is a true Texas mountain race. The races will start at around 5,000' altitude and climb to 7,192'. Most of the trail is low desert with runnable terrain and some easy, technical segments. The climb to the North Franklin Peak is a combination of steep climbing and switchbacks.

And be prepared. It might get chilly out there.

The 2019 Version of this race will coincide with 'The Franklins 200M/200K" 

100 Miler

100M will be 3 loops of 33.70 miles with approximately 21,000 feet of gain and descent. The loops will be run the counter clockwise rotation. 


100k will be 2 loops of 31.8 miles with approximately 13,500 feet of gain and descent. The loops will be run the counter clockwise rotation. Relay teams for the 100k are 2 people. 

We did a course preview at Austin Trail Running Company. Check it out! 

Greg Luffey wrote a great write up on the Franklin Mountains Sky Race. This is about 95% of the course. The only difference is we don't go up Aztec Caves.  Instead, we go to Upper Sunset to climb to Mundys. We also don't use the Ridgeline Trail to get to the gap, we use Cottonwood.
