Becoming The Iron You
An analysis of training volume for long distance triathletes
Back in May, I spent a fascinating week in the company of the iron men and ladies at Club La Santa, watching them prepare for Ironman® Lanzarote. We volunteered on the day - and spent six surreal hours in T2, rubbing sun cream into triathletes who had just finished biking. After hours of exertion in the hot sun, there were lots of very weary people, with nothing between them and rest, except for the small matter of a 26.2 mile run.
Quite amazingly, it didn't put me off the idea of triathlon - indeed, I came away with the crazy notion of a five year plan to get myself to the point where I too could become a 'long distance triathlete'. It feels far enough away that I might be able to bend reality sufficiently by then to make it physically possible.
The obviously huge consideration is the amount of training needed in order to stand a chance of making it through the day if not unscathed, then with as little scathing as possible. Although most competitors looked a bit tired, there was very little outwardly-expressed doubt as they fuelled up, changed socks, and took a moment to contemplate what lay ahead.
One of the benefits of being the editor of Fetcheveryone is the chance to mine for patterns in thousands of race and training experiences. Now obviously, doing a full distance triathlon is not everyone's cup of tea (I'm gonna need some sugar in mine, and plenty of brandy), but there have been 384 brave attempts recorded on the site over the last dozen years. And of these, 194 are accompanied by a full record of everything that happened in training during the 12 months before the race.
The first thing to ask is "how much training is involved?" - so you can work out whether it's a feasible thing to fit into your life. The result from our triathletes, looking at the average for the entire year is an almost-amazingly neat one hour per day (1h2mins if you must know, or 378 hours in the year). Of course, there's a lot of variation - but 80% of our sample trained between 40 and 94 minutes a day - so an hour seems a fair compromise.
As we've noticed when looking at running, there's a correlation between training volume and outcome. Despite plenty of variation amongst individuals, grouping athletes by their finishing time tends to group them around a training volume too. The sub-13 ironfolks tend to exceed the hour a day average, and the sub-14 crew fall just short.
If you're a pure-play runner who trains at nine minutes a mile, 378 hours would make for a 2,500 mile year, which would put you in rare company indeed (less than a hundred Fetchies in 2015). That sounds pretty tough, but the saving grace for sore knees is that swimming and biking take up a good share of that time. How much? Here's the breakdown in percentage terms, along with some figures for a middle-of-the-pack athlete:
So the typical running requirement is a slightly more manageable 982 miles, if you're willing to pay for it by cycling 2721 miles and swimming 74! Only two triathletes put swimming first. Biking was the most time-consuming, with 131 athletes giving it top billing on their schedules.
Here's a diagram showing how lava formed the island of Lanzarote - or alternatively, it shows all our triathletes, ordered by overall training time from least to most. About 10% get by with less than 300 hours, and at the other end, some are willing to put in well over 500 hours.
Despite the very real possibility that long distance triathletes might be hovering on the edge of insanity, they are not crazy enough to go out and do exactly one hour every day, for the entire year. Even the most rudimentary training plan involves some sort of build up, with a bit of a cutback before the race to help ensure you're itching for it. By splitting the year into 13 four-week blocks, I was able to look at the percentage of training in each, to see the shape of the training year:
One thing we know about triathlon is that it's quite a seasonal sport. Of all the long distance triathlons listed on Fetcheveryone, 84% of them are between June and September. So the shape of the first part of this graph could be a reflection of the triathlon 'season', when most athletes will be competing regularly in the summer months. But then we see a steady build up from about 40 weeks out, with a peak in the penultimate four week period. This peak contributes 11.1% of all the training - and if we plug that figure back into what we found earlier, our mid-pack athlete will peak with a four week block of 42 hours of training. Using the same exchange rates as earlier, that's roughly 8 miles in the water, 300 on the bike, and 110 on foot.
Even the gentler end of that graph, with 5.4% of the training volume, means that the flatlands of ironman training are 20 hour months - and right now, that still feels like more of a mountain. Sure, I've put in a few in the last dozen years - but they are anything but normal. Clearly, there's some way to go - but it's nice to get a flavour of what lies ahead!

Fascinating
if you've got enough time on your hands to look into all this, then you've definitely got enough time to train for IM, you know you want to

Wow. Great stats there Fetch. Your graphs are looking more and more swanky too. If I include cross training (gym, core, bit o swim, bit o bike) I'm c. 1 hour per day (20 hours a month low, 40 hours a month high) and I do a 9 to 5 (well, 8-6) job. My lad is all growed up, unlike yours, so maybe wait until you're in your late 40s?! I have no doubt that if you want to, you can do it!

Fascinating. Pleased that my percentages on each discipline roughly match the averages above (13/54/32 October, 20/51/28 November) at an average of an hour a day. Shame my race isn't until July.

5 years? That's a leisurely stroll to Ironman. You're a bit late for 2017 so aim for 2018.

Great work:)

why 5 years? Why not either next year, or if there is a particular race you want to do that is full, the year after?

It's a saying, more than anything

Breaking it down like that is brilliant. Makes all of us be able to realistically see what we would need to do for one. However 5 years is too long I reckon you could do iron 3 so what you waiting for ?.....

I'm doing too much swimming and not enough biking!

Really interesting as someone considering it for the future. I'd love to see (if the data is there), what the sub 10 guys did, and the sub-11 as well!

Excellent analysis. Now of you could split all that down by age and gender...

Back when it was still a paper magazine you could buy in a shop, iTriathlete Europe/i did a similar breakdown. I seem to remember their cycling proportion was greater (compared to running) - they had a less run-centric emphasis than Fetch, which you'd expect I think.

I've always said that you have a lovely way of getting a message across. Reading the blog in your voice made it even better. I am still adamant that I will never Tri.

If you put together a training plan, I'll import it to my log and train with you. I'm sure I'm not the only one. Let's set up a fetch Ironman training group.

Love the graphs there. Oranj, I don't think the emphasis tags work in comments...I tried it a little while ago with no effect.

As a runner who clocks less than 600 red miles per annum, clocks most of the green miles commuting to work and prefers finding a lake to gain blue miles at a time in the year when I don't turn blue myself
I can confirm that IM completion is totally doable on modest mileage. Actually completing my third IM this year I rather surprised myself with a quick time too 
*when* you do sign up I'd be more than happy to answer any questions you have

This is so interesting, thank you

Just seen this - very, very interesting - thank you
And you could definitely get to a long distance Tri in 2-3 years - or less. I went from being a runner to 1/2 Ironman in 6 months - very do-able. And a whole new world of lovely kit to need - but that's a totally different thread .......

To comment, you need to sign in or sign up!Most of the running rules apply to all the disciplines , don't build up 1 sport too quickly and you will avoid burnout and injury. Consistency and a sensible split between the sports and accept you are not a runner - cycling is king.
It helps a lot if you can do 2 sessions a day too.
If you can swim, bike and run a bit, you should be fine to get round in a half decent time, then you can decide if you want to go back and beat your time, or do something more worthwhile with your life
I'm doing the Tenby long course tri next July.
and yeah why 5 years? And Fraggle is right you so have the time!!
