From this point to Fort Collins, CO you will traverse the “high plains” of the U.S. The services between major towns will be few if any, so carry lots of water and always phone ahead to ensure that a needed service or overnight lodging is open and available.
Fort Collins is a great place to take a layover day. It’s a college town (Colorado State University), it’s a platinum rated bike-friendly city, and it has over a dozen bike shops. Before leaving town, be sure to carry a good supply of groceries for the next two days’ ride up the Poudre River canyon and over the Continental Divide. There are only a couple of convenience stores between Fort Collins and Walden, CO.
At Walden, CO you join the original TransAmerica bike route headed west!
