they're not very long. they're 33mi and 23mi respectively. but they're also 4,200 and 3,300 feet vertical respectively. many of the popular gravel races are all day long affairs. these are mostly offroad, a little bit of everything. down in the desert, up in the pines, elevation ranges from 3,300' above sea level to 7,000'. are these too short to be worth the while?
