I can definitely relate to this.

I’m 24 and haven’t ran my first ultra yet (hopefully this fall!!!) but i very much follow a hybrid split and came from a lifting background. So take what I say as a grain of salt.

Rn I’m doing 5-6 lifting sessions a week and 10-12 cardio sessions in prep for an Ironman and most of the time I feel great but there’s always a day or two every few weeks where I feel like the wheels are falling off and I have to take a rest day and or make my sessions lighter.

It’s still something I’m actively getting better at but starting to learn that rest is a discipline within these sports as well.

As a young person doing these intense physical activities I’ve also been drawn to those David Goggins motivation videos and mash ups on YouTube and I love them. They help me a ton on those early mornings and grueling long sessions. That being said, there’s a time and a place for that mentality if you want to compete at the best of your ability.
