Sion's account of his successful UTMB adventure really is "what they don't tell you, " and now I don't feel so bad that I may never get the chance to run UTMB. But, I am very impressed by Sion's accomplishment. Congratulations, and thank you for this video.

[Ohjeezno]

This is great! These are the stories we don't hear from Kilian or Jim as frontrunners. I so much appreciate you guys. Keep pushing, keep going! Excellent recap video 🥰

Love the pure honesty, I was about 30 mins behind you and walked with you for a little time just outside of Champex Lac. As such I can back up your claims, crazy race :) Congrats on the finish, you showed courage !

Huge congratulations!!!! I hiked/ran it in six days and at the end couldn’t imagine doing it nonstop! What an accomplishment! Thank you for the debrief ❤️👊

[brettruns]

Some great insights into the race that I’ve not heard before. That double pole overtake manoeuvre is classic 😂

[HeidiKimber-gbbq]

What an adventure you had! Thanks for giving us an idea of what UTMB is really like.

Skipping the staircase through the garden was a really shit, unsportsmanlike, rude, disrespectful move imo. That’s how local people end up not wanting these events near them

[AaronRobinson]

I really enjoyed this. You have an engaging style and it’s great to see the race being dissected like this. More please. I did the MdS 10 years ago so going back to watch your experience.

Big thanks! This is one of the best and most candid review of the UTMB experience. Its so real as though we were in it ourselves. Congratulations!

The bench nap / phone on the face story is so rad

Great job and great video

Great video mate, well done completing UTMB! Interesting to hear your experience with the French on the trail. My brother did CCC and suffered extreme dehydration, basically collapsed on the track. Dozens and dozens of people went past and not a single person stopped to ask if he was okay. Eventually the first person to stop was a fellow Aussie who sorted him out with some salt tablets - I think that says a lot. I'm glad you were able to persevere, that's a bucket list achievement 🙂

Awesome insight into a wild 43 hours. Congrats Sion on getting through it considering your ankle and the hallucinations. You put in the hours, the kms, the climbs, the hikes - you deserved to get over the finish line. Loved the series. We need words however regarding your form at 5:39, 14:46 and 21:00. You can't cheat, push people out of the way, then fart in their face 😂 He's gone native.

I’ve known @sion for only 6 months and one thing I found immediately is he puts 100% into everything! What an amazing review. People spend 10k+, sacrifice time with family, significant leave from work every year to do this race, so it’s actually extremely helpful having an honest review. Tash, the edit and music was superb you should be just as proud as Sion for this series. Please do more insane things Sion, and Tash, please make videos about them! Haha

The YouTube algorithm led me here. Congrats, mate, on your adventure at UTMB 2024—that was my 5th TDS! You should give La Diagonale des Fous a go. It’s a whole other level of French ultra-trail experience—pure and one of a kind. Peace and blessings

[braddomek]

You’re a one of a kind human that’s for sure! Candid and inspirational, amazing work.

[MatthewEatonBri]

Incredibly honest and detailed review! Thanks for all the insights!

[bhaveman]

Great insights into what is like to be a middle of the pack runner. Thank you for this. ❤
I have the honor to start this year and your story will help me in preparing what to expect.
