The beginning of Magnolia Rd. is very steep, averaging over 9% for the first few miles, with some sections nearing 20%. Your bicycle will need good climbing gears. The gravel section of Magnolia (miles 11-18) is in excellent condition. The first aid station is near mile 20 in Nederland at Tin Shed Sports.
