We Attempted An Ironman Without Food & This Is What Happened!

Published 2022-09-18
Can you complete an Iron-distance triathlon completely fasted, only being allowed fluids? We’ve experimented with various different fuelling sources on the GTN channel over the years, but this could be the ultimate challenge! Could Heather or James complete it?

    What other insane challenges would you like to see us take on?
  • @travismcgarry
    There’s a reason Heather was an Olympian… elite mental strength. My new mantra when in a dark place during training and racing “Be more like Heather” 💪🤯
  • @CarrieCole09
    Whoa, Heather! Absolutely amazing! You are such an inspiration. Sure you are fast and physically accomplished, but the mental toughness is astonishing. Heroic!!!👏👏👏
  • @agenthoini
    28:57 "keep going at a really low intensity" aka she ran 33k at my 5k pace (after having already been out there for 7 hours without fuel) 😂
  • @stephenneal23
    Heather just showed that difference between a professional and an olympian. You're a beast!
  • @rgh622
    I have no words... I'm sitting here watching Heather do her unfueled Ironman whilst I eat a hearty meal and I couldn't believe what I was seeing! I cannot imagine that kind of fortitude. You're an inspiration!
  • WOW! I'm speechless. The empath in me was crying when James called it quits followed up by Heather being terribly cold and miserable. Ive raced been freezing and could only imagine how they were feeling being cold/ wet/ and no fuel. Heather absolutely crushed it! I was rooting for her to just keep moving but I'm so incredibly in awe that she made it with 9km to go! wow!
  • @ocbyn
    Heather is my new hero and I have no interest in doing a triathlon, but loved the warts and all approach to this. Good to show the honesty.
  • @esoteric404
    damn. don't know what else to day. great job Heather. the mental strength you need to go 10 hours at that pacing w/out any caloric intake is unreal. truly inspiring
  • I don't normally comment on anything, but what an amazing effort from Heather! Truly inspirational!
  • Heather & James well done on doing this challenge. Total respect for you both.
  • Been watching GTN for years, you all continue to educate and entertain. From newbie to experienced triathlete, GTN has been the staple show for triathletes.👍🏽
  • @ab0s3r
    Heather is such a freaking monster. Heads off to her big time!! Very impressive
  • @btmzi55
    Amazing! Cold and rain on the bike is the worst even with proper fueling. What an effort. Fascinating that Heather was even able to start the run then actually felt better as the fat burning really kicked in. Well done both of you, especially Heather!
  • Incredible work from you both, especially for Heather’s mental fortitude battling through the run, just incredible
  • Before I even watch this, I know heather will be absolutely fine. I’ve seen too many endurance YouTube videos and she has been on the move for 5 hours and casually announces she has only had 1 jelly baby!
  • @SendingStache
    Some serious grit from both Mark and Heather! That being said, this is the coolest video ever from GTN and I’ve been loving your content for a long time! Heather was insanely inspirational - that was sooo awesome! What a beast!
