I Tried Jakob Ingebrigsten’s Toughest Training Day

Mark has tackled some wild challenges recently—running a full marathon in crocs, attempting a sub-4-minute mile (downhill), and even training like Alex Yee. But now, he’s pushing himself even further. 💪 Mark takes on one of the toughest workouts out there: the legendary double-threshold session (aka "Norwegian Method") used by Olympic champion and world record holder Jakob Ingebrigtsen. This intense training session truly puts Mark to the test—will he conquer it or crumble? 🏃‍♂️🔥 Join this channel to get access to perks: https://www.youtube.com/@gtn/join 00:00 Taking on Jakob Ingebrigsten's workout 00:29 Who is Jakob Ingebrigsten and what's his training? 01:51 First session - On the treadmill 02:31 Lactate testing is key 03:25 The lactate threshold reps underway 07:14 What is the Norwegian Method? 08:42 The track workout 11:20 First set completed 11:47 Start of the second set 14:00 Conclusion and thoughts of the Norwegian Method 16:10 Using lactate measurements Useful Links Join GTN YouTube Memberships 👉 https://gtn.io/JoinGTNmemberships Subscribe so you don’t miss a thing 👉 https://gtn.io/subscribe Submit your Photo and Video to us 👉 https://gtn.io/UPLOAD Check out the GTN Shop 👉 https://gtn.io/TeamKit GTN Training Plans 👉 https://gtn.io/qonrQw Insurance: Viewers in the USA and UK can explore Insurance products 👉 https://gtn.io/insurance Would you ever try a double threshold session? 👀 Watch more on GTN... 📹 Why Even Beginner Runners Should Vary Their Run Pace 👉 https://youtu.be/5H4fgmTpB48 📹 Watch our Editor’s Choice Playlist 👉 https://gtn.io/editorschoice 📹 Watch our weekly show, The GTN Show 👉 https://gtn.io/GTNshowPlaylist Photos: © Triathlon / Getty Images 🎵 Music - licensed by Epidemic Sound 🎵 Chopper - Damma Beatz Curb Your Angst - Glass House No Novelties - Johan Glossner Parrot Tongue - Rymdklang Soundtracks Sidewalk Shimmy - Guustavv Mash - Wildflowers Hit'n Switch - Damma Beatz The Turn (Instrumental Version) - Martin Hall #gtn #triathlon #swimbikerun #swim #bike #run #thresholdtraining #lactate #anaerobic #aerobicfitness #workout #runworkout #olympicrunner #worldchampion The Global Triathlon Network (GTN) is the world's biggest triathlon YouTube channel, with new videos every day!
