The Hallowrock 10K/5K/1M

The Hallowrock 10K/5K/1M is held in Las Vegas, Nevada, on October 25, 2026. Three trail formats are offered: a 10K, a 5K, and a 1-mile fun run/walk (1.6 km). Start times were not published at the time of writing. The Halloween-adjacent date gives the event a festive feel, and the range of distances means the whole family can find something to run or walk.

Desert trails around Las Vegas are usually dry and rocky, and late October brings pleasant temperatures for racing. The 10K is a good target if you want a hard trail effort without heavy preparation: eight weeks of regular running with a weekly session on dirt will prepare you well. The 5K is ideal for a first trail race, and the 1-mile fun run/walk is untimed in spirit, suited to kids and to anyone who simply wants to take part. Wear shoes with some grip and carry water, even for the shorter distances.
