Welcome to my Blog

Capturing memories from around the world. Like marathons on every continent, climbing the world’s highest peaks, backpacking over 75 countries, an Ironman triathlon, multiday hikes, whitewater kayaking, bike touring, and lots of challenges in between. This is my story, and everything I've learned along the way.
