Lace up your running shoes for the scenic St. Patrick's Day Half Marathon, 12K, and 5K on March 14, 2026, in Boulder City, Nevada. This renowned event offers an unforgettable running experience amidst the breathtaking beauty of the Lake Mead National Recreation Area, just 18 miles from Las Vegas. Runners will traverse the historic Railroad Trail, known for its unique journey through six old train tunnels that once transported concrete for the Hoover Dam. The course provides stunning vistas of Lake Mead and the surrounding desert landscape, making for a truly memorable race day.

The Half Marathon course begins at the Historic Railroad Trailhead, featuring an initial out-and-back segment before leading runners through the iconic tunnels towards a turnaround point near the Hoover Dam. While described by some as "Fast and Flat," the course does present a few hills, with the loop near Hoover Dam noted as a challenging, steeper section with some rocky terrain. Runners can expect well-organized support with aid stations providing water and Gatorade, along with friendly and enthusiastic volunteers. A unique touch to the race is often a bagpiper playing as runners enter the first tunnel, adding to the festive atmosphere. Typical race day conditions in mid-March boast pleasant highs around 72°F and lows around 51°F, with a minimal 1% chance of precipitation, creating ideal running weather.

Whether you're tackling the full 13.1 miles, the 12K, or the 5K, this St. Patrick's Day celebration promises a historic and scenic adventure. Participants often praise the well-organized nature of the event and the impressive finisher medals, making it a highly anticipated race for locals and visitors alike.
