Redding, United States · Sunday 17 January 2027
Located in northern California along the Sacramento River, Redding sits in a region known for its outdoor recreation and natural beauty. The area offers runners a chance to experience the Sierra Nevada foothills and the diverse terrain that makes northern California such a compelling destination for endurance athletes. The landscape transitions between open ridges, forested sections, and river valleys, giving the race a varied character that keeps your attention over 26.2 miles. The course itself is a trail marathon with moderately rolling hills that demand respect without being punishing. You'll gain 219 meters of elevation spread across the full distance, which means the climbing is never relentless but rather distributed in a way that keeps you honest throughout. The elevation runs between 147 and 318 meters above sea level, so you're working at a reasonable altitude. The terrain includes a notable tunnel that runners pass through multiple times across different sections of the course, which serves as both a navigational landmark and a bit of character that distinguishes this race from standard road marathons. This is the kind of course that rewards steady pacing and trail-running fitness rather than pure speed. Race day takes place in January, which offers mild winter weather typical of the region. The Boston Qualifier designation indicates this is a competitive field, and the race organizers provide relay options for those who want to participate differently. Aid stations, course markings, and spectator areas are established along the route, with bib pickup coordinated ahead of time. This is a well-organized event that attracts serious runners looking for a qualifying opportunity without traveling to the East Coast during the peak racing season.

Redding Marathon is a trail race, meaning the course includes unpaved surfaces such as dirt, gravel, or forest paths. Trail surfaces are inherently slower than road courses due to uneven footing, technical sections, and often steeper gradients. Trail-specific shoes with good grip are recommended, and runners should expect a finish time 10-20% slower than their equivalent road marathon time.
