CUP-FREE RACING: We are very excited to introduce our support for Cup-Free Racing in this year’s race, and we encourage you to choose to race Cup-Free. It’s easy, it’s fast, and it’s already happening at major road races including the BolderBoulder, the Madison Marathon, the Estes Park Marathon, and hundreds more marathons and half-marathons across the country. Carry the personal hydration device of your choice (hand held bottles, hydration belts, or the revolutionary new HydraPouch personal hydrator), and fill it in about one second from HydraPour coolers at every aid station. Click here to learn more about Cup-Free Racing, and get 10% off your entire HydraPouch purchase. We’ll still have pre-filled cups available at our aid stations (this year), but we hope you’ll help us take this big step towards eliminating cups by choosing to race Cup-Free.
