Description:

Rio Del Lago 100 Miler begins at beautiful Beal’s Point, Folsom Lake State Recreation Area in the Sierra-Nevada Foothills. With Folsom Lake as the sparkling back drop, you’ll traverse oak woodland and meadows, over bridges and creeks, up and down switchbacks and along the most spectacular trails in the area. This scenic 100-mile foot race combines two of The Best trail races in Northern California: American River 50 and Way Too Cool 50K. The 100-mile course includes a variety of terrains that novice and veteran runners alike will enjoy.

Runners climb Hazel Bluff on single-track trail, then go right back down the other side where the course turns left and meet up with the Middleridge Trail. It’s good to be in the middle of Middleridge Trail. You can sing ABBA’s greatest hits, or if you’re not feeling that rowdy, try getting everyone to join you in a round of that Row, Row, Row Your Boat song. That one resonates at mile 70 or so. After winding through the Middleridge trail, the course joins at Sunset and Main Street by the Shadow Glen Stable area which eventually meets back with the paved bike trail at Black Miners Bar. From there, the course gradually ascends past the Rainbow Bridge and back towards Beal’s Point where you will see your crew for the first time!

The course will wind down under the Powerhouse and on Leidesdorff Street in Old Historic Folsom. The course remains on the south side of Lake Natoma on the American River Parkway through Willow Creek and then to the Aquatic Center. At the Aquatic Center, the course crosses the bridge up to the Nimbus Bluffs.After reaching Beal's Point, runners will enjoy single track trails and head north on the path worn by gold miners in search of riches: The Pioneer Express Trail, near the entrance of the Granite Bay State Park. Runners will continue to Granite Beach on the north side of Folsom Lake.

Runners leave Granite Beach and continue north towards Twin Rocks and Auburn, CA. Runners will pass through Horseshoe Bar and Rattlesnake Bar. No, we aren’t talking about stopping at local pubs, but trails above the sand bars where miners would pan for gold, but there ARE Aid Stations at each, which is kind of like finding gold. The route continues to Power Plant, Avery's Pond, Dowdin's Post, and arrives at the base of Cardiac Hill. We did ask the park officials to lower the top of the hill for you, but they stubbornly refused, so you have to climb the whole thing. Take a deep breath and then ascend Last Gasp to the Auburn Dam Overlook. (NOTE: Pay attention to the route you’re following because you’ll be coming back down this stretch in the dark and you’ll be tired. We mark the route with this in mind, but runners still need to pay attention.) Exiting the Overlook, runners descend on the Western States Trail to the historic No Hands Bridge (109 years old but doesn’t look a day over 90!) If you get wobbly about heights, don’t look over the rail, just run to the aid station on the other side of the bridge.

Trekking poles are NOW allowed from the Auburn Dam Overlook (mile 44.25) until the finish line!!!

From No Hands Bridge, runners will cross Highway 49 at Lower Quarry. The Rio course now joins forces with the iconic Way Too Cool 50K course. You will run along the scenic Quarry Road continuing through Main Bar. You will make your way to Auburn Lake Trails, Goat Hill and descend to the Upper Highway 49 crossing. From Upper Highway 49, you will follow the WS trail to the Cool Fire Station. From Cool, the course heads out Haul Road for about 1.5 miles on the paved road before making a right-hand turn, rejoining the trail and making your way back towards No Hands Bridge.

From No Hands Bridge, runners will re-trace their footsteps to the Auburn Overlook (running DOWN Last Gasp, take that!) and back onto the trails through Cardiac, Rattlesnake Bar, and Horseshoe Bar. Back through the Meat Grinder to Twin Rocks, back to Beal’s Point to cross the finish line and celebrate! And when we say celebrate, we here at NCU headquarters mean EAT DONUTS. Flop yourself down on the grass and contemplate how good it is to be alive, to have donuts, to have however many toenails you still have, to live in a world where donuts were invented, to be among people who know exactly how you feel at this moment!

Rio 50K Endurance Run

We are excited to continue the highly popular Rio Del Lago 50K! This is a lightning-fast course. (Hint: if you are looking to set a PR, sign up today!) The 50K will start at Beal’s Point with the 100 milers at 5 A.M. Both race distances will run together until Twin Rocks (just past Granite Beach) and the 50K’ers will turn around and retrace your steps back to Beal’s Point. The course traverses the American River Parkway, the infamous Johnny Cash Trail and breath-taking views of the Nimbus Bluffs. We’re not bluffing!!! The terrain combines both pavement and trail (way more trail than pavement!!!) for novices and veterans alike. This course is perfect for those seeking their 1st ultra and those wanting to set a new 50K personal record.

Tips for Crewing
Ultra runners really like a little extra TLC that can only come from friends and family. That's where Crew Teams come in to play. If you have agreed to be part of a Crew you are in for a great time! Here are some tips and pointers to make your crew experience as enjoyable as a gig like this could possibly be.

GUIDELINES FOR A SUCCESSFUL RDL - To be able to successfully run and complete Rio Del Lago 100 Miler, it is HIGHLY recommended that you have completed at least one 50 miler run (whether it be a race or in training) before October 25, 2026. And it is also suggested that you finish your run within an official time from any other event. For example, American River 50 has a 14 hour limit. This is in addition to your normal training. We are recommending this to help you get to the finish line. Remember, this is a 100 miler and will tax your body tremendously! Good luck!!
