Redding Spy Rock Loop Challenge invites runners to explore scenic trails and steep elevation changes during the crisp autumn season. This free event serves as an excellent warm-up for upcoming fall and winter races, offering both experienced trail runners and casual participants a chance to conquer challenging terrain. The loop route encompasses approximately 8 miles with roughly 1,000 feet of ascent and descent per lap.

This event provides an ideal setting for runners looking to build endurance and stamina in preparation for summer races ahead. Participants are encouraged to complete their chosen distance anytime during March but must submit a GPX or Strava link by the end of the day on the 28th via email at stinktaterbug10@gmail.com. This event is designed to cater to runners who appreciate scenic routes and challenging elevation changes, making it an unforgettable adventure in the heart of Redding's natural beauty.
