@Matt_Hutchings Hi Matt! Great that you are starting on Huel - let us know how you find it! As far as the Insanity workout, I’m not sure, but there is a thread for extreme exercise/ ultramarathons Huel for ultra marathon running? and also just found a thread for Insanity Workout Huel with Insanity workout but i don’t think there has been anyone who has tried it yet. Hope that is helpful!
