Killeen Half MaraFUN

Killeen Half MaraFUN is a half marathon (13.1 miles) in Killeen, Texas, on December 19, 2026, starting at 8 a.m. as part of the Centex race series. Runners of every level are welcome, with awards for age groups and for the overall placings. Packets can be collected before the event and same-day registration is available, and there is a four-hour limit on the course.

Four hours is generous for the distance but not unlimited, so it is worth doing the arithmetic before you enter: that cut-off works out at roughly 18 minutes per mile, which a steady run-walk cycle will beat comfortably. If you are aiming at an age-group award instead, a series race like this rewards knowing your competition and running the middle five miles at goal pace rather than reacting to whoever is beside you.
