The 7-Hour Triathlon Week: What to Keep and What to Cut

Sunday night, and you're already bargaining a 7-hour triathlon week away. Tuesday is a trainer at 6 a.m. if you sleep. Thursday's run lives only if the noon call moves. Saturday is the one block longer than an hour, a birthday party stapled on the back.

The week holds when every piece lands. Plenty of weeks, one piece doesn't.

For Olympic distance, this is the shape I want in those hours. Two sessions with real intensity. One bike or one run long enough to leave a trace. Everything else easy enough that those three still happen. Six medium workouts will make you tired. They will not make you faster.

Stephen Seiler calls that medium place a black hole. On That Triathlon Show he describes the 45-minute run that starts near threshold and stays there. Easy days creep up. Hard days sink to meet them. You never get fresh, so the hard day was never hard.

Grey. All week.

I see athletes call this discipline. The junk was the pace. Tuesday, Thursday, Saturday. Same trap.

He has said a polarised split still showed up around eight hours a week, even around five. Most minutes below the first lactate threshold. A smaller share above the second. He calls the hard share zone 3. A five-zone watch uses zone 3 for the middle. Wrong target.

His fix for six one-hour days is blunt. Give one hour away. Make a single session two hours. Take the day off. That stretched easy ride does a job six rushed ones never reach. He still wants one real hard session. The point is to stop the slide into the middle.

What should a 7-hour triathlon week include?

Mikael Eriksson is warier of the slogan. On the follow-up episode he half-agrees with a listener who said a strict polarised split doesn't scale to six-to-ten-hour weeks. Keep lots of easy work and a smaller slice that hurts. Near seven hours, he would allow about 80 percent easy, rather than 90.

Six and a half hours is 390 minutes. Ninety percent easy leaves about 40 minutes above easy. Eighty percent leaves about 80. I'd keep the harder minutes in that gap, nearer an hour than a token 15. Hear "mostly easy" and delete the hard part, and you didn't follow the rule. You dodged it.

With Friday included, the middle of those ranges is a little over six hours. A seventh hour goes on Saturday or a second swim. It does not become a third hard day.

Monday is rest. You bought it by letting Saturday get long.

Tuesday is the bike, about an hour. Twelve easy minutes, then four repeats of six minutes hard with three easy minutes between them, then spin down. That's 24 hard minutes. Stop when the stroke gets messy, with a rep still left.

Wednesday is 40 to 45 minutes in the water, about 1,800 to 2,200 metres if that's your range. Steady swimming, then eight fast 50s. Cut the steady metres if you're fading. Keep the 50s.

Thursday is 40 to 45 minutes of running, easy enough for full sentences. Four strides of about 20 seconds only if the legs feel ordinary. How slow an easy triathlon run should feel is a separate argument, the one in this piece. If you can't talk, this isn't Thursday.

Friday is an easy bike of 40 to 50 minutes, or a second swim if the pool is simpler. Bad sleep or a brutal day means you skip it. That's allowed.

Saturday is the bike, two hours to about two hours 15. Put 20 to 30 minutes steady in the second hour, short phrases only. The rest stays easy. On that easy portion, heart rate at 15 minutes should look like heart rate at 60. Seiler uses the match to check you're under the first threshold. If it climbs hard, you started too hot.

Sunday is an easy run of 45 to 50 minutes. Next week the long session is a 75 to 90 minute run, and the bike shrinks. A Q&A on that show treats the alternation as the piece to protect on six to eight hours for a first Olympic. Weekday scraps don't replace it.

How many hard sessions fit in seven hours?

About two, and rotate them. Bike with swim one week. Bike with run the next. A fast swim can sit beside a hard bike. A hard run beside it will not be as kind.

Short reps beat a threshold sit inside a 45 to 60 minute window. Ten to twenty hard minutes still leave a warm-up. Forty-five minutes at threshold is the whole slot, and nothing easy remains.

Seiler's classic is four repeats of about eight minutes near 90 percent of max heart rate. With a real warm-up it spills past 45 minutes. It fits Tuesday. It does not fit the school-run gap. I'd rather ride four by six minutes cleanly than relabel a sloppy tempo as threshold.

When a hard run lands in the same week as those bike reps, drop the steady minutes. Saturday stays easy. Two hard days already spend the non-easy minutes.

What do you drop when the week collapses?

The steady chunk goes first. Then the second interval session becomes easy. Then Friday vanishes. The long session shrinks before it dies. Ninety minutes still counts.

Skip the makeup. Missed Tuesday reps do not move to Sunday after the long ride. The week doesn't owe you intensity. You'll just be sore on Monday.

Life stress is already a load. The hours are short because of work and kids, and the body still gets the bill. If Tuesday arrives and you're cooked, the interval bike becomes an easy spin. Leave Thursday's run alone.

Spare easy days come out of the sport you already own. Natasha Van Der Merwe coached a strong swimmer in his 50s to a low-nine Ironman on 10 to 12 hours. Two swims or four, much the same result, she said on That Triathlon Show. Dodge the pool because the bag is annoying, and his result isn't yours. A swim that limits you stays after Friday dies.

Conrad Goeringer puts a floor near six hours, and eight to ten as a solid span from sprint through 70.3. Ironman, in that conversation, sits nearer ten, with some race weeks around 14. His article makes the life version plain. He pictures a parent on 70-hour weeks racing sprint or Olympic from seven honest hours. Seven is a real Olympic week. It is thin if you want a deep 70.3 on the clock.

He wants more touches than this sample gives. Three rides, four runs, two swims, each one short. Put a two-hour Saturday under that and the other sessions average about 30 minutes, commute included. I'd rather finish six. If running is the weakness, keep the easy jogs and downgrade the hard run. A trainer belongs in the same conversation. Weekday rides die once you add the search for a safe road, so he treats a trainer as basic kit.

A printed sheet still thinks you rode the reps. RacePal feeds sleep and HRV into the next day and eases off when you're already behind. On seven hours there is no spare session to burn.

Questions athletes actually ask

Can you train for an Olympic triathlon on seven hours a week?

Yes, if the aim is to race that distance and get fitter across a season. You will not match a talented athlete training double the hours. Sprint and Olympic are where seven hours gives up the least. A 70.3 you care about on the clock wants nearer eight to ten.

Does a polarised split still matter at seven hours?

It matters because the failure here is a whole week in the middle. Near 80 percent easy is a fairer target than a strict 90 when the hours are short. Count minutes. In Seiler's model, zone 3 is the hard work, not the tempo band on a five-zone watch.

Should you skip the swim when the week gets tight?

Drop a spare easy session in the sport you already own. If the swim limits you, keep one swim ahead of a third easy bike. A strong swimmer can live on two short swims. A weak swimmer cannot live on zero.

What if the only open window is 45 minutes?

Use it. Ten to fifteen minutes of hard bike work inside that window is a session. A half-effort shuffle for the whole 45 turns the week grey. If you're cooked, make it truly easy and go home. Walking the last minute is fine.

Before Monday, write three lines where you'll see them. Long session. Hard bike. Easy days, with the word easy on the page. If the party cuts Saturday to 90 minutes, you still trained. The week fails when every slot turns medium and you call that discipline.
