King Half Marathon

King 7-miler and Half Marathon - Memphis, TN

The King 7 Miler and Half Marathon is a trail running event on the Wolf River Trails in Memphis, Tennessee, organized by Mamba Trail Runners and scheduled for August 15, 2026. The course uses the same trail system as the Mamba 100 and runs primarily on smooth, flowing singletrack that is mostly flat and highly runnable.

Distances offered:

• 13.1 miles Half Marathon
• 7 miles 7 Miler

The Half Marathon follows the full Mamba loop with a shortened section to create the official 13.1 mile distance; the full loop is 14 miles. Aid stations are placed on course, with one station in the early miles and additional stations in the later miles (approximately mile 8 to 9 range). The Start/Finish area includes a fully stocked aid station with food, cooling towels, fans, and ice-cold water.

This is a cupless race; participants should bring a handheld bottle, hydration vest, or other personal hydration. Course marking uses orange ground flags; runners should follow flags positioned on the right side, though two course sections have flags on both sides near the bridge areas. Packet pickup is available the day before at the Wolf River Refuge Trailhead and on race morning. Parking is at the Wolf River Refuge Trailhead with overflow parking on the grass behind the lot.

All participants receive a custom finisher medal. Awards recognize the Top 3 overall male and female finishers and age group winners for both distances. There are no refunds or roll over credits. Summer weather in Memphis can be hot, humid, and stormy; organizers may postpone or cancel the event for safety. Visit the organization's website for the most recent information.
