Come join us for the first ever FOLSOM 100-mile ultramarathon circumnavigating Folsom Lake! The Folsom 100 will start from Granite Bay state recreation area in the five percent parking lot at 5:00 am on May 6th, 2023. Runners will have 34 hours to complete the 100-mile loop around Folsom Lake. You will be starting from Granite Bay and traveling through, Loomis, Auburn, Cool, Salmon Falls, El Dorado Hills, Folsom Point and back to Granite Bay! We have combined large sections of our other races (Meat Grinder, Snowberry, Red Dragon, and Dead Truck) into this one EPIC route! The views around Folsom Lake and river canyons are stunning as you work your way through this incredible course. There will be a 54-mile race that will end at the Skunk Hallow Parking lot in Pilot Hill. Parking is very limited here and drop off/pick up is advised. There will be no shuttle this year. There is also a 100-mile 2-person relay! Grab a friend or loved one and both earn a buckle! The switch out will take place at the Skunk Hallow Parking lot in Pilot Hill.  Sign up fast and earn your buckle! We have now added a 20-mile distance to this year's event. This will start at Granite Bay and Finish at ADO. This is our second year and hope to show everyone that signs up a great time!
