It's time to wind back the clock to a venue that dates back to the 90's, back when baggy jeans were still in style! The Boulder Reservoir, last raced in 2018, is known for one thing and one thing only - the beaches of pain. Get ready for some sand bursting, punchy little climbs, along with some sweeping high speed recovery sections!
