It's true! The Fartlet Running Podcast is back! Josh returns from his tropical getaway to the Big Island of Hawaii, and boy, does he have stories. From dodging molten lava flows to bonding with chill sea turtles who clearly have better swimming form than he does, Josh's vacation recap is equal parts adventure and humidity.

Meanwhile, poor Coach Blu stayed behind in the land of smog and sorrow, bravely battling Utah's infamous winter inversion while trying not to cough up a lung. Tune in as the duo compares "volcanic air vs. toxic air", debates whether sea turtles could qualify for Boston, and discovers that sometimes the most dangerous run is just trying to breathe at home.

Grab your headphones, your inhaler, and maybe a lei, this episode's hotter than a lava field and twice as gassy.
