The Rohring Course is a 5K loop with 45-50 feet of ascent / descent per lap. 75% of the course is dirt or DG trail. The balance includes some bike path blacktop, sidewalk and concrete. There is grass surrounding a portion of the sidewalk and concrete, so you can use that if you wish. The course traverses the boundary of a golf course, and the inside of a city park. It crosses a parking lot driveway ( where you will park your car near the start / finish ) and one residential street. We recommend gaiters. We will serve typical ULTRA fare at our venue. Water, Electrolyte Replacement Fluid, Sugary and Salty Snacks, PBJ sandwiches and other old-school food will be aplenty. If you need some special, scientifically-formulated, performance-enhancing, mind-altering gooey or pasty stuff to fuel your engine... feel free to bring it and share with your friends.
