My girlfriend is awesome! In preparation for our upcoming Colorado backpacking trip, we did some endurance training or what I like to call LSD (Long, Slow Distance) hiking. We walked along Braes Bayou on a very hot, humid day. My GPS odometer read 15.5 miles, but the track file only captured 15.1. Anyways, my girlfriend completed the hike in good shape. I was proud of her since this was her all-time longest hike to date.
