I've been weightlifting for the last 2 1/2 years and built a pretty solid physique. Currently I'm 27M 5'10 185 lbs and around 15-16% body fat. I'm kinda getting burnt out of weightlifting and looking for something new. I have a few friends who are getting into marathons/triathlons. Id like to start running and maybe do a marathon next year but I kind of find it hard to believe that I won't lose a bunch of muscle mass running that much. Most of the influencers I've seen who do run marathons etc seem to be juiced or lifting 10+ years before getting into hybrid training. What are you guys experiences for those who have transitioned from body building to hybrid training? I'm a big fan of Jeff Nippard. Are there any good recommendations of influencers for hybrid training that are natural and explain the science behind it?

TLDR

Transitioning from body building scared of losing muscle mass. Looking for other people's experiences who have transitioned. Also any good recommendations of influencers for hybrid training that are natural and explain the science behind it?

Joseph Smith clearly was sealed to multiple wives but are there any sources that show he had sex with any of them? Ideally the sources would be credible and something the church would normally recognize.
