Gulf Coast Series - Day 3

Set your sights on the picturesque shores of Gulfport, Mississippi, for the Gulf Coast Series - Day 3, happening on Wednesday, March 18, 2026. This esteemed event, part of the Mainly Marathons Gulf Coast Series, welcomes runners to choose their challenge from marathon (26.2M), half marathon (13.1M), 10K, and 5K distances. Renowned for its vibrant and friendly community, the series attracts passionate runners who appreciate the flexibility to participate in a single race or tackle multiple events across the region.

The course itself promises a fast and flat road experience, often featuring an out-and-back layout with repeats within a scenic state park, ensuring little to no elevation change. Runners can anticipate picturesque scenery, with many reviews highlighting runs "along the beach" and unobstructed coastal views. Typical race day conditions in mid-March offer ideal running weather, with comfortable highs around 72°F and lows near 53°F, and only a 13% chance of precipitation.

What truly sets the Gulf Coast Series apart is its commitment to runner support and a welcoming atmosphere. Thanks to a unique multi-loop course design, a single, comprehensive "aid station" acts as a refueling hub, offering an impressive array of refreshments. Expect everything from fruit, jelly beans, and sandwiches to water, Gatorade, and even hot coffee, all powered by their dedicated "Loony Lunchbox" mobile kitchen. The series also prides itself on a "no time limits" policy, award-winning medals, and a supportive "Loony Community," ensuring that every participant can achieve their goals in an encouraging environment. Finishers in races longer than a half marathon even receive a custom metal-stamped nameplate.
