Rockledge Rumble Trail Run

Rockledge Rumble Trail Run takes place in Grapevine, Texas, on November 14, 2026, in the Dallas-Fort Worth area. Three trail distances are staggered across the morning: the 50K (31 miles) at 7:00 AM, the 30K (18.6 miles) at 7:30 AM and the 15K (9.3 miles) at 8:00 AM.

The name gives you a clue: the trails around Grapevine are rocky and rooty, with plenty of short, sharp climbs even though total elevation stays modest. That makes the 15K a good first trail race for road runners, the 30K a solid intermediate challenge, and the 50K a manageable first ultra with mid-November temperatures that are typically friendlier than the Texas summer. Build over 12 to 16 weeks with weekly long runs on technical ground, add some strength work for ankles and hips, and practice picking your feet up on tired legs to avoid the late-race trips that rocky courses punish.
