For John Clark’s (JC) full bio revisit season 3 episode 4: https://www.buzzsprout.com/2437656/episodes/16363345

We sit down with JC to unpack his first winter ultramarathon finish at the Iditarod Trail Invitational 350, where dragging a gear sled through Alaska’s deep cold turns basic tasks like eating and navigation into real risk. We also talk through the behind-the-scenes prep, the gear, and the small decisions that add up over ten relentless days. 

• what makes the Iditarod Trail Invitational so dangerous and so compelling 
• hauling a 50 to 55 pound sled across lakes, rivers, and mountain passes 
• gear failures leading to frostbite
• how the ITI qualifier camp teaches wet-gear survival and vapor barriers 
• gear iteration under extreme cold including sleeping systems and face coverage 
• early navigation mistakes and why staying on the packed route matters 
• Rainy Pass rescues and the winter ultra culture of helping others 
• the mental grind after the pass with long gaps between aid and sleep 
• the final push with shiver bivies and trail naps 
• what JC would change before trying the race again
