Join ALS Therapy Development Institute's Ragnar for Research program to experience the Ragnar Texas Trail on Oct. 18-19, 2019.

   The Ragnar Relay held about an hour outside of San Antonio at Flat Rock Ranch in hill country, offers trail runs full of expansive views, Texas live oak, rolling hills, granite boulders and prickly pear cacti. 

Our teams of eight fearless runners fundraise for the ALS Therapy Development Institute (ALS TDI) and race through some of the most spectacular scenery in the U.S.  As a team member, you will also party the day away at Ragnar Village, and at night, rest your legs next to the campfire, chow down on s’mores and relax with your team. At the end of it all, you will have cheered, celebrated, wore crazy costumes, and conquered challenges together in this epic two day, one night adventure.
