"I took this to show the trailer and gear we were hauling. We were using BOB trailers, designed specifically for mountain biking. It was a very effective way to carry our stuff, but they dramatically change the way the bike feels. They probably weighed 50 pounds (23 kilograms) each; the photo gear alone weighed 15 pounds (7 kilograms).

"I used a selective focus [to take this photo], so you don't really look down, instead you look at Shidan and the trailer. The trailers were a big part of our effort, a big added challenge. We definitely felt that doing it in two days was hard because we had to haul more weight and travel more miles over such a short period of time."
