Lace up for a vibrant St. Paddy's Day celebration with purpose at the 4th Annual Run the Rainbow for CHILDREN'S, set to take place on Saturday, March 21, 2026, in Jackson, MS. This inspiring event offers a full spectrum of distances, including a 26.2M marathon, 13.1M half marathon, 10K, and 5K, ensuring a challenge for every runner and walker. As typical race day conditions in March bring comfortable highs around 73F and lows around 50F, with a modest 17% chance of precipitation, you can anticipate enjoyable weather to hit the streets of Mississippi's capital city.

The Run the Rainbow course, starting and finishing at the lively Hal & Mal's in downtown Jackson, is known for its rolling hills, particularly through the charming neighborhoods of Belhaven, Eastover, Fondren, and Woodland Hills. While the 5K route features 52 meters of elevation gain and the 10K has 100 meters, runners tackling the longer distances can expect a challenging yet scenic journey that winds through historic areas and past the University of Mississippi Medical Center campus, offering a glimpse of the Kathy and Joe Sanderson Tower at Children's of Mississippi. Participants have praised the great and plentiful aid stations, well-stocked with Gatorade and gels, and the enthusiastic on-course support from volunteers.

What truly sets Run the Rainbow apart is its unwavering commitment to Children's of Mississippi, the state's only children's hospital, with all proceeds directly benefiting this vital cause. Runners often find a touching moment along a stretch of road adorned with pictures of honoree children, a powerful reminder of the impact of their efforts. Beyond the rewarding cause, the race culminates in an amazing St. Paddy's after-party at Hal & Mal's, complete with live music and a celebratory drink ticket. Finisher medals are awarded to all participants, with many runners highlighting their impressive size and unique design. This event is cherished for its "HUGE spirit" and the vibrant, community-focused atmosphere it fosters.
