Photo @tylermetcalfe | A traveling cyclist rides towards the towering mountains of Grand Teton National Park in northwest Wyoming. Last year I embarked on a cross-country bike ride from the headquarters of @natgeo in Washington, D.C. to the shores of Olympic National Park in Washington State. The trip took me through ten states, four national parks, and 4290 miles over the course of 107 days. Check out the feature "American Bike Project" at natgeo.com for more.
