The 70.3 North Carolina Triathlon returns to Wilmington on October 17, 2026 — and if you're racing, spectating, or simply commuting that weekend, you need to know exactly which roads will be closed and when.
What to Expect on Race Weekend
Wilmington will host one of the region's premier long-distance triathlon events, drawing thousands of athletes for a 1.2-mile swim, 56-mile bike leg, and 13.1-mile run through the city and surrounding areas. Road closures begin as early as October 15 and extend through the evening of race day, October 17. Planning your route in advance will save you significant time and frustration.
"Closures span multiple days — from pre-race setup on October 15 all the way through the final finishers crossing the line on October 17 at 8 p.m."
Pre-Race Day Road Closures
Preparations begin two days before the gun goes off. Starting October 15 at 8 a.m. and running through October 17 at 8 p.m., Water Street from Market Street to Princess Street and Princess Street from Water Street toward Front Street will be closed to through traffic. These closures allow crews to set up transition zones, timing equipment, and athlete corrals safely.
On October 16, an additional closure takes effect: Hanover Street between North Front Street and North Second Street closes at 8 a.m. and remains closed through October 17 at 8 p.m. Residents and businesses in the affected blocks should plan alternate access routes well ahead of time.
Race Day Bike Course Closures
The bike course generates the most extensive closures of the day. Starting as early as 5:15 a.m. on October 17, athletes will take over Causeway Drive and all roads intersecting Eastwood Road and Martin Luther King Jr. Parkway in the eastbound direction. Several ramps and exits along I-140 and U.S. 421 will also be restricted during peak race hours. Most bike-course closures lift by 2 p.m., once the final cyclists have cleared the course.
If you regularly commute via these corridors, consider leaving significantly earlier than normal or identifying a parallel route before race morning. Local traffic apps may not reflect real-time closure status, so check official city and race communications the night before.
Race Day Run Course Closures
The run leg winds through downtown Wilmington and carries the longest closure window of the entire event. From 3 a.m. through 8 p.m. on October 17, expect closures on N. 2nd Street, Brunswick Street, Hanover Street, and multiple sections of Front Street. The early start time for these closures reflects the logistical work required to mark the course, position aid stations, and ensure athlete safety before the first runners arrive.
Downtown businesses, hotels, and parking structures in these corridors should communicate alternate access instructions to their guests and customers ahead of race weekend.
"The run course closures begin at 3 a.m. — plan any downtown trips the night before or after 8 p.m. on race day."
Where to Find Official Race Information
For the most current closure details, detour maps, and athlete information, visit the official race organizer's website and the City of Wilmington's transportation notices. Conditions can change in the weeks leading up to race day, so bookmark both sources and check them again the week of October 13.
