Flat Branch Ultra, Columbia, Missouri - February 20, 2027
The Flat Branch Ultra is a trail running event organized by Ha Ha Racing Events in Columbia, Missouri. The race uses rails to trails corridors and features flat, fast USATF certified courses for both distances. The start and finish are at Martin Luther King Jr. Memorial Park.
Distances:
- 50K
- 25K
The USATF certified 50K follows the MKT Trail onto the Katy Trail toward Rocheport, running along the Missouri River and beneath bluffs. The route is an out-and-back that joins the Katy Trail about 7.5 miles from the start. A notable landmark on the 50K is the nearly 400-year-old Burr Oak at about 8.5 miles. The 50K course is eligible for Missouri 50K state records. In 2026 several single-age state records were set and two overall Missouri 50K state records were recorded with times of 3:15:06 (men) and 3:26:47 (women); a nonresident later logged 3:01:32 and is listed separately under state record rules.
The new-for-2027 USATF certified 25K is an out-and-back run primarily on the MKT Trail and turns before the Burr Oak, sharing the same start and finish area as the 50K.
Field size is limited to 125 total entries. Aid stations, drop bag service for the 50K, finisher awards, overall awards, posted race photographs, a no refund policy, and a requirement to sign a USATF waiver at packet pickup are part of the event details.
