Fitting in aerobic training amid full weightlifting schedule

Most of the weight lifting talk I see is about fitting in weights to improve cycling performance. My dilemma is that I want to be aerobically viable for racing in Cat3, but secondary to my supertotal training (Squat, Bench, Deadlift, Snatch, and Cleans). I raced in the past and have wanted to come back to competition for a while, but have also recently built a home gym where I can dig into the lifts that I also love.

My current lifting program is 4 days/week. I’m having trouble imagining how I consistently pull off 5-10 hours of riding simultaneously, especially during build phases. I think what could work is if I pull back on the lifting during the build and specialty phases. But I guess, starting from lifting 4 days/week, are there ideas out there on how to fit in medium aerobic volume?

For strength and endurance concurrent/hybrid training I’ve heard good things about Alex Viada, he has a website/ coaching company Complete Human Performance. I’ve never done their programs but maybe check out some of his writings and podcast appearances for some ideas.
