The Active Joe

The Active Joe provides fun, friendly, and affordable opportunities for people to get active, with most activities centered around the Dallas-Fort Worth metroplex in Texas. Producing several races during the year, they’re best known for the New Years Double event, which includes double marathons that many Texas ultrarunners use in their training for winter ultramarathons.

It all began in 1991 on a bike. Original Buff® Headwear was developed by Joan Rojas, a textile manufacturer, who struck gold one day while riding his motorcycle on the desolate Catalan roads of Spain. An avid biker since the 1970s, Rojas found that while he was out riding with his friends, he needed extra protection from the elements. In the two decades since, Buff® has become an international, multi-sport phenomenon. Our seamless multifunctional headwear protects athletes on the windiest Alpine slopes, the hottest deserts, and on plenty of rivers, lakes, roads and trails in between. Today, you can buy a huge lineup of Buff® products in more than 70 different countries and we’re still growing.
