The Austin Distance Challenge is a series of the most prestigious local running events starting in the fall and leading up to the Austin Marathon & Half Marathon in February. The races increase in distance as the series progresses, making the series a natural component of many Austin runners’ training. In its 20th year, the Distance Challenge is hosted by the Austin Runners Club (a 42 year old local nonprofit) and raises funds for our beneficiary charity, which will once again be The Trail Foundation, an organization that protects and enhances the Ann and Roy Butler (Town Lake) Trail.
