TLDR: Marathon training plans are written for people with time. I don’t have time. I have three kids, a full-time job, a wife who also works, and a hockey league that doesn’t care about my long run schedule. What I figured out is that you only need three runs a week to make this work. Protect those three. Be flexible with everything else. Finish the race.
Nobody warned me that signing up for a marathon with three kids would turn my entire household into a military logistics operation. My wife didn’t sign up for this either, technically, but here we are. She’s been unbelievably patient about the 5:30am alarms and the Saturday mornings I disappear for two hours. I try not to push my luck.
I’ve done this once now. Going in I had no idea what I was doing. Coming out of it I had a system. This post is about the system.
What I Was Working With
I want to give you the actual picture before we get into the approach, because “marathon training with a busy schedule” means something different when it’s abstract versus when it’s my specific Tuesday night.
My Tuesday night in week 9 of training looked like this: I had a tempo run on the schedule, my youngest had a fever all day, and I had a work call that ran 30 minutes long. The tempo run didn’t happen. I did 40 minutes easy on the treadmill at 9pm after everyone was in bed and called it a win.
That’s the real version. Not “I optimized my schedule and found a training window.” I salvaged what I could and moved on.
My training background coming in was decent but not running-specific. I’d been lifting five days a week for a few years, so I had a solid base of general fitness and leg strength. I’d run two half marathons and was consistently getting in 20 to 25 miles a week in the months before I started the full plan. The lifting helps and hurts in equal measure. My legs are stronger than most marathon runners’, which means I can handle load, but I also carry more muscle than is aerodynamically ideal for 26.2 miles and my recovery is slower.
The schedule constraints were the real variable. I work from home, which sounds like it should help, but it mostly means my “training windows” are also when my kids expect me to be available. Three daughters. Wife works full time. No grandparents nearby. The idea of a two-hour midweek training run is genuinely hilarious.
The Only Three Runs That Actually Matter
Here’s the thing about marathon training plans that nobody tells you up front: most of the runs on the plan are not critical. The easy recovery runs, the maintenance miles, the “just spin your legs” sessions — those are the runs that exist to pad your weekly mileage. They matter, sure. But they’re not the runs that get you to the finish line.
The three runs that actually matter are the long run, one quality workout per week, and one easy run that keeps your aerobic engine ticking between the other two.
Everything else is bonus. That reframe changed everything for me.
Once I understood that, I stopped agonizing over missed runs mid-week. I had three non-negotiables. Everything else was opportunistic. Some weeks I hit five or six runs. Some weeks I hit three. The three always happened.
The long run was Saturday morning. Out the door by 5:45am, back before 8am, everybody still asleep or at least contained. My wife knew this was sacred. I knew I had exactly that window and if I missed it for a non-emergency reason it would be a real problem. It’s been rescheduled twice in two training cycles. Once for a family thing that was genuinely unavoidable. Once because I had a stomach bug and trying to run 18 miles with a stomach bug is an objectively bad idea. Both times it moved to Sunday morning, same deal.
The quality run happened on my lunch break. I work from home and I have a treadmill in my garage, which makes this possible in a way it might not be for everyone. I have about 45 minutes. A 30 to 35 minute tempo run fits in that window comfortably. I’m not doing 10-mile tempo efforts. I’m doing 4 miles at threshold pace and getting back to my desk before my afternoon meetings start. That’s enough. The workout is the stimulus. You don’t need it to be long to be effective.
The easy run was the most portable. Before anyone woke up, after the kids went to bed, doubled up with a lunch run on a lighter day. Easy pace is the great equalizer because your body can absorb easy miles at basically any time of day without needing a lot of recovery. I’ve run at 4:30am more times than I’d like to admit. I’ve also run at 9:45pm. Both work. Neither is fun. Moving on.
Here’s roughly what the mileage looked like across the 16 weeks:
| Phase | Weeks | Long Run | Quality | Easy | Weekly Total |
|---|---|---|---|---|---|
| Base | 1 to 4 | 10 to 12 mi | 4 to 5 mi tempo | 8 to 10 mi | 22 to 27 mi |
| Build | 5 to 10 | 14 to 18 mi | 5 to 6 mi intervals | 10 to 14 mi | 29 to 38 mi |
| Peak | 11 to 14 | 18 to 20 mi | 6 mi tempo | 12 to 16 mi | 36 to 42 mi |
| Taper | 15 to 16 | 12 mi down to 8 | 4 mi | 8 to 10 mi | 24 to 30 mi |
I didn’t hit every number every week. I hit most of them most weeks. That was enough.
The Treadmill Saved Me and I’m Not Embarrassed About It
I used to have opinions about treadmill running. Those opinions are gone now. Three kids will do that.
The treadmill in my garage is the single most useful piece of equipment I own as a parent who runs. Bad weather? Treadmill. Kid home sick and I can’t leave the house? Treadmill. 4:30am and I don’t want to run through my neighborhood in the dark? Treadmill.
The knock on treadmill running is that it’s boring and biomechanically different from road running. Both true. Neither matters enough to skip a training run over. I put on a podcast, set the incline to 1%, and get it done. Miles are miles. The only run that didn’t happen is the one you skipped.
The Things That Went Wrong
Week 11 I was running peak mileage, lifting five days a week, and playing hockey. My legs felt like wet concrete by Thursday of that week. I ran my 18-miler on Saturday on legs that hadn’t fully recovered from anything in ten days. It was a grind.
The right call was to drop the hockey game and reduce lifting volume during peak training weeks. I knew that. I made the wrong call anyway because I didn’t want to miss hockey. I paid for it through weeks 12 and 13 with legs that never quite felt fresh. The performance wasn’t ruined but it was blunted. In my second cycle I dropped hockey during peak weeks without thinking twice about it. Problem solved.
The other thing I got wrong was nutrition, specifically race-day fueling. I didn’t start practicing with gels until week 12 of 16. That’s way too late. Your stomach has to learn to process fuel while you’re running at race effort. It does not figure this out on its own. I had a rough miles 18 to 22 in my first marathon largely because my gut wasn’t trained for what I was asking it to do. In my second cycle I started gel practice in week 6, every single long run, no exceptions. That part of the race was a completely different experience.
Also: the taper is going to make you feel terrible and you’re going to be convinced you’ve lost all your fitness. You haven’t. Week 15 I was tired, irritable, and sure I’d somehow gotten slower in the last 14 weeks. I hadn’t. Every runner I’ve talked to describes the exact same thing. Trust the taper. Don’t add miles back in because you feel weird. The taper is doing what it’s supposed to do.
What It Cost and What It Was Worth
Long runs eat Saturday mornings. That’s real money in a household with three young kids, and I want to be honest about it because most marathon training posts skip this part.
There were weeks during peak training where I was physically present Saturday afternoon but mentally just empty. My wife called me out on it once, gently but directly, and I’m glad she did. I had to get better about actually showing up after the run, not just physically occupying the same house. That meant not spending Saturday afternoon on the couch recovering. It meant genuinely being there for whatever the kids had going on.
Build recovery into your family calendar, not just your training calendar. If Saturday is a long run day, make Saturday afternoon good for them. That’s the deal.
What it was worth: I crossed the finish line of my first marathon in 4:26:48. Not fast. Exactly what I was quietly hoping for without saying it out loud. Not injured. Not depleted.
How to Actually Start
If you’re reading this with a full family schedule and wondering if this is even possible, here’s what I’d tell you.
Build your base before you start the plan. Six to eight weeks of consistent running, three times a week, easy effort, building toward 20 to 25 miles a week. Starting a 16-week marathon plan undertrained with a packed schedule is how you get injured or burn out by week 8. Get the base first.
Then pick your three runs and put them on the family calendar. Not your personal calendar. The family one. Talk to your partner before week one, not during week nine when you’re asking to disappear every Saturday morning. Get actual buy-in. This doesn’t work as a solo project you’re quietly managing around everyone else.
The long run slot is sacred. Everything else moves around it.
Try This First
This week, figure out when your three windows are. Not your ideal windows. Your actual ones. Where is there 30 to 45 minutes three times in your real schedule this week?
Write them down. Get up early for at least one of them. See if you can do it three weeks in a row.
If you can, you can train for a marathon.
