We are in the early hours of a marathon dayhike over the four peaks of New Hampshire’s Northern Presidential Range, but they are treating it like a short, interval-training workout.
Powered by the blindly stratospheric self-confidence of athletic teenage boys, they do this repeatedly as we hike a trail paved with rocks the size of bowling balls and dorm-room refrigerators. Like two spooked deer, Marco and Liam bound ahead of us on the trail, pause to wait for us to catch up, and then sprint ahead again.
