With family, I have completed bike trips across Florida, Georgia, Tennessee and the Natchez Trace. These trips, as well as other outdoor adventures, pose a challenge I seem to thrive on. There's a chance I won't make it - 3,000 miles is a long way. Undertaking arduous challenges where the outcomes aren't assured, or perhaps even when it is unlikely, teaches the most valuable of lessons. That's as true for research on the important questions of our times as it is for bicycle treks.
Life is short - run as much as possible.
