Rio Del Lago 100 Mile Endurance Run

Folsom to Auburn and Back!

November 6-7, 2021

Welcome Back Rio Runners!

Rio Lago 100-mile Endurance run is returning for to celebrate our 20th Anniversary! This race brings together veterans and novices alike. Whether this is your 1st or 20th Rio 100, we are doing cartwheels to greet you in person on November 6th!

You can expect first class race management from start to finish. Well stocked aid stations, along with drop bag locations are on course. Our enthusiastic volunteers will provide inspiration and motivation on your journey from Folsom to Auburn and back.

As we continue to navigate the COVID galaxy, permit protocols and restrictions require a new look. While we are optimistic by early fall, we will be able to operate as in "normal times" we are uncertain on our final capacity numbers as it relates to crews and pacers (we know we will have them but unsure if locations will be paired down). We will update you as we learn more in early summer. In the mean time, we are confident each of you will channel your inner Luke Skywalker and defeat the dark side.
