The Course


Rio Del Lago 100 begins at beautiful Beal's Point, at Folsom Lake State Recreation Area in the Sierra-Nevada Foothills. With Folsom Lake as the sparkling backdrop you'll traverse through 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 3 of The Best trail races in Northern California: American River 50, Sierra Nevada Endurance Runs and Way Too Cool 50K.

The 100 mile course is 99% trails and consists of two loops. Runners will begin their 100 mile journey on the pavement levee out of Beal's Point (following the AR50 course). After 1/4 mile on the pavement levee, runners will turn left on to the 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 cross the entrance road to the park and continue on the Pioneer Express Trail towards Granite Bay Horse Assembly where the 1st of the courses many Aid Stations is located. Runners leave Granite Bay Horse Assembly 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 rather passing over the sand bars that miners would pan gold from, but there ARE Aid Stations at each). The route continues to Power Plant, Avery's Pond, Dowdin's Post, and arrives at the base of Cardiac Hill. Runners will take a deep breath and then ascend up the brutal Cardiac Hill to the winding flume trail crossing Maidu Rd., before arriving at the Auburn Dam Overlook. Exiting the Overlook, runners descend on the Western States Trail to the notable 101 year old No Hands Bridge.

From No Hands Bridge, runners will traverse the Western States trail and wind their way to the Cool Fire Station. Upon exiting the Fire Station, runners will then be treated to the Way Too Cool course. Runners will tread the Haul Road for 1.25 miles before heading left on to the single track trails. These next 8 miles (Olmstead Loop) are some of the most scenic and beautiful terrain our trails offer with breathtaking views of the American River Canyon. Runners will traverse the Secret Trail on this section and loop around back to the Cool Fire Station. Cut-off time is 5:00pm. Runners will make the Olmstead Loop again before leaving Cool.

From Cool, the trail will follow the Western States trail back to No Hands Bridge and the 50 mile mark! This part of the race follows the Sierra Nevada Endurance marathon route. Runners will re-trace their footsteps back to the Auburn Overlook (running DOWN Cardiac Hill, take that!) where Pacers are now able to join in the fun. From there, runners follow the trails back to Beal's Point to arrive at mile 78. Runners see their crew and can be joined by another Pacer (if that is part of their race day plan!) Cut-off time is 4:30am. (If you're one of the lucky folks running after midnight, be on the look out for our glowing pinwheels. If you find one, pick it up and carry it to the finish line for a very cool sponsor prize!)

For the final loop, runners will retrace part of the first loop by leaving Beal's Point and running to Horseshoe Bar. This will be the turnaround for the last loop. Runners will go back to Beal's to cross the finish line and celebrate!

  • Pacers do not need to check in prior to running, but, need to clearly identify themselves at every aid station.
  • Pacers should be well conditioned to travel the distance with their runner.
  • Pacers are responsible for their own transportation to and from their starting location. Race management will not organize or facilitate any shuttle.
  • Pacers may eat and drink from the aid station tables. Pacers must enter and exit with their runner. No "muling" is allowed. "Muling" is when a pacer carries any supplies (drinks, food, clothing, etc) for the runner outside of the aid station area.

Any unclaimed drop bags on race evening will be donated to charity on Monday following the race. We will NOT mail drop bags after the event. Thank you for your cooperation and understanding with our updated policy. Race management works very hard to expedite drop bag retrieval in a timely manner. However, we ask for your patience. All drop bags on course will not be returned to Beal's Point (finish line) until the aid station is officially closed. If you need your bag sooner, please make arrangements to retrieve. Thanks for your understanding and assistance with these guidelines.

Crew Driving Instructions

Excellent areas from which to view runners are Beal's Point, Granite Bay Horse Assembly, Rattlesnake Bar, Overlook, No Hands Bridge and the Cool Fire Station.

Park fees: Rio Del Lago travels through the California State Parks – Gold Fields District and the Auburn State Recreation Area.

All crewing and viewing areas are located in the California State Parks District and require a ($12) fee per vehicle unless you have a Golden Poppy Pass. If you frequently patron the Rio Del Lago trails (also home to AR50, Sierra Nevada and Way Too Cool), please consider supporting the CA State Parks and purchase a Golden Poppy Pass.

Crews are responsible for paying the day use fees ($12) for entrance in to the State Parks. If there is not a ranger present at the kiosk in to the parks, you are still responsible for self-payment through their drop box as you enter the parks. Crews need only to pay one time at a State Parks kiosk, but must show their receipt upon entry to each park at the entrance.

  • Please observe all posted signage and placards by the County and CA State Parks.
  • NorCalUltras will not be responsible for any violations or tickets.
  • Absolutely no crews are allowed at Horseshoe Bar and Dowdin's Post. Crewing at one of these locations can result in runner disqualification.

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...
