Half Ironman With A Full-Time Job: A Realistic 70.3 Schedule

The most common reason people give me for not signing up to a half Ironman is time. Not fitness, not the swim, not the distance. Time.

It's a fair objection, because most 70.3 plans you find online were written for people whose Tuesday afternoon is free. Twenty hour weeks. Double sessions with a nap in between. Read one of those with a full calendar and a job, and the sensible conclusion is that the race isn't for you.

I've built this race around a full working week for years now, and I want to be straight about what that actually takes. It is not effortless and it is not a hack. But 8 to 12 hours a week, held for sixteen weeks, gets you to a 70.3 start line properly prepared. That's roughly the time most people spend on a series they're half watching.

Here's how those hours actually distribute.

The week

Six endurance sessions and three strength sessions, across six training days. Two of those days are doubles, which is the part that makes the whole thing fit.

Monday. Strength, 45 to 60 minutes. Starting the week with a lift means you hit it fresh, and it protects the session busy people always drop first.

Tuesday. Double. Swim, 45 minutes, and bike, 60 to 75 minutes. The swim is technique and intervals, the bike is quality work. Split them across the day if that suits you better, one before work and one after.

Wednesday. Double. Strength, 45 minutes, and run, 45 to 60 minutes. Threshold or tempo on the run, depending on the phase.

Thursday. Swim, 45 minutes. A single session, deliberately, because Tuesday and Wednesday were long days.

Friday. Strength, 45 minutes. Short, and easy to move if the week has gone sideways.

Saturday. The long ride, 2 to 3.5 hours, building across the block. This is your one genuinely large time commitment, and it sits on the day most people can protect it.

Sunday. Long run, 60 to 100 minutes. Then done.

That's it. Six of the nine sessions are an hour or less. The two doubles carry the midweek load, and the whole thing hinges on one weekend morning you defend properly.

The bricks come later. In the second half of the block, once the base is there, you start running off the bike so that race day isn't the first time your legs feel that. It's a specific sensation and it is worth rehearsing.

What makes it work

The short sessions are not filler. The instinct when time is tight is to skip the 45 minute swim and save yourself for the long ride. Do that for a few weeks and your swim falls apart, which costs you far more on race day than the ride you protected. Frequency beats duration in the disciplines where technique matters.

Strength stays in. This is where most time-crunched triathletes cut first, and it's the wrong cut. Three lifts a week is what keeps you durable enough to absorb the running volume without breaking down in week eleven. The athletes who get injured mid-build are almost never the ones who lifted.

The plan is written in advance. When you're tired and busy, the decision of what to do today is itself a cost. Having the session already sitting in TrainingPeaks removes that entirely. You open the app and execute. No negotiating with yourself at 6am.

Not every week is the biggest week. Sixteen weeks isn't sixteen weeks of climbing. There are lighter weeks built in, and a taper at the end. The people who burn out are usually the ones who treated every week as a test.

Being honest about the trade

You will get up early. Some weeks the schedule will collide with work, and you'll move a session or lose one, and that has to be fine. One missed session in a sixteen week block is noise. Four missed weeks is a different story.

What I've found is that the structure itself does most of the work. Not motivation, not discipline in the abstract. Just knowing exactly what today's session is, and that it fits into something.

That's the whole idea behind how we programme. Every session has a job. Strength holds the endurance together. The endurance builds across months rather than weeks. Nothing is random, because random is what falls apart the moment your week gets difficult.

If you want the sixteen weeks already laid out, that's exactly what the Triathlon 70.3 Hybrid Athlete plan is: swim, bike, run and strength in one progression, with brick workouts, race pace sessions and a proper taper, delivered through TrainingPeaks. Built for people training 8 to 12 hours a week, because that's the constraint most of us are actually working with.

You can see how we structure it before you decide.
