The big thing is how it all fits in to what you're doing. I can only let you know what I do from my perspective.
I do my lifting at night, because my kid likes to train with me. He is working towards being a nationally competitive athlete in the under 10 category (yes, he is working toward it, his goal - my bank would prefer he'd rather just have fun and rock locally but he's pretty good so we run with it). He does his thing, I do mine. It's a bonding thing. I do my conditioning on my lunch at work. I choose to walk 2.2 miles on squat/dead days, and do sprints / bomb around on a 20" bmx race bike for typically about 3.2 miles, or go for a jog at 2.2 miles, on the pressing days / off days, depending on how I feel and where in the season we are. The sport is a year-long season. If we're in the thick of it (summer, big races weekly), I dial back jogging and accessory work when lifting, and focus more on sprints. If it's between "A" races (i.e., there is a week off of the big ones), I ramp up accessory work and do some jogging in addition to the sprints just for that low-key work. If I'm burnt up, I chill out a bit, if I'm feeling spunky, I put the accessory work back in.
YMMV, but I study when the clan is asleep, so I have to manage fatigue, training, ability to focus on my work during the day, and keep up with everything else.
