The famous Laugavegur trail. 34 miles / 6,000 ft of climbing through ancient lava flows, rivers, snow fields, thermal vents, rhyolite mtns and just about everything epic Iceland has to offer. I always try to fit the trek into my summer galavants. This was my second time doing it in a day, nothing like a long walk in the mtns. The @breitling endurance pro kept me on time with 12 hours total time, what a day.
