2026 Gulf Coast Series - Day 3 (MS)

Prepare for a memorable running experience at the 2026 Gulf Coast Series - Day 3 (MS), taking place on Wednesday, March 18, 2026, in scenic Gulfport, MS. This event, offering both 10K and 5K distances, is part of the esteemed Mainly Marathons Gulf Coast Series, known for attracting a vibrant community of passionate runners. Participants consistently praise the series' friendly atmosphere and the flexibility it offers, allowing runners to engage in a single event or challenge themselves across multiple states.

Runners can anticipate a fast and flat road course, often featuring an out-and-back layout with repeats within a state park, boasting little to no elevation change. Gulfport's coastal location, with an average elevation around 33-39 feet above sea level, ensures a largely level journey, making it ideal for those chasing personal bests or simply enjoying a comfortable pace. Expect picturesque scenery, with reviews frequently highlighting runs "along the beach" and unobstructed coastal views. Typical race day conditions in mid-March include comfortable highs around 72°F and lows near 53°F, with only a 13% chance of precipitation, creating favorable running weather.

One of the standout features of Mainly Marathons events, including this Gulf Coast Series race, is the exceptional support. Due to the unique multi-loop course design, a single, comprehensive "aid station" provides an impressive array of refreshments. Runners can refuel with everything from fruit, jelly beans, and sandwiches to water, Gatorade, and even hot coffee, thanks to their dedicated "Loony Lunchbox" mobile kitchen. Beyond the generous provisions, the series is celebrated for its "no time limits" policy and award-winning medals, fostering a welcoming "Loony Community" that encourages every participant to achieve their goals. The combination of a scenic, flat course and unparalleled runner support makes the 2026 Gulf Coast Series - Day 3 a must-do event for runners of all levels.
