Discover the joy of community running at the Renton parkrun on March 21, 2026, a free, timed 5K event held every Saturday in Renton, WA. This welcoming gathering invites participants of all abilities to walk, jog, or run along the scenic Cedar River Trail. The course is a precisely measured 5000m out-and-back route, predominantly paved and offering picturesque views of the Cedar River, with some sections immersing you in a lush, almost rainforest-like setting with abundant trees. While generally flat, the course does present minor elevation changes, making it suitable for both personal best seekers and those simply enjoying a Saturday morning outing.

Anticipate pleasant, mild conditions for late March, with typical highs around 55F and lows around 40F, accompanied by a low 15% chance of precipitation, perfect for an invigorating start to your weekend. The start and finish are conveniently located a few hundred feet beyond a bollard on the trail, accessible from the parking area near the I-405 overpass. While aid stations are not typical for this informal 5K, the focus is on self-supported enjoyment and community spirit.

Renton parkrun stands out for its inclusive, volunteer-led atmosphere, which has fostered a friendly environment since its launch in November 2017. Participants often appreciate the encouraging messages sometimes chalked on the path and the opportunity to greet fellow runners on the out-and-back course. After completing your 5K, extend the camaraderie by joining others for a post-parkrun coffee at Common Ground Coffee & Cupcakes in Downtown Renton.
