Join us April 27, 2024 for the 43rd annual Sunflower Marathon, Half Marathon and Relay! This unique course begins at 2180 feet elevation in Mazama and includes well marked deer trails, single track trails, and gravel roads. Stunning views of the Methow River, North Cascades and Chelan Sawtooths abound from flower carpeted meadows and fields. At two points, racers climb to 2600 feet. The finish is at about 1600 feet in Twisp. This course traverses private property that owners generously allow use for this one-day only.


The Marathon course is a marathon-plus length at 26.8 miles. Expect breathtaking scenery and some sustained climbs and descents. Elevation +2,520/-2,350.
