TSC Mysteries: Why is a Swimming Mile only 1650 Yards?

This is the first installment in a series of articles to research and unravel the mysteries of swimming.  These mysteries range from serious to silly, but always in good fun, and will hopefully help to satisfy your inner swim-nerd. If you have any good mysteries (or bad ones, we’re not picky!) please send them our way via the “submit content” page, and we’ll see if we can figure them out!

When is a mile not really a mile? When it’s measured in a pool.

Today’s question was inspired by an email I received from a guy named Paul Arvin. He is a life-long swimmer, having swum in high school, taught swimming in Malaysia, and done underwater photography for the World Wildlife Fund. He wondered why the 1650 yard freestyle is known as a “mile” when in fact it is 110 yards short of an actual mile (for those not familiar with feet and yards, a true mile is 1760 yards). It’s something I’ve always wondered, but have always just written off some strange misnomer that had something to do with the mathematical evil that is the Imperial system of weights and measures.

But no longer will I accept that as an excuse. So I set off across the internet and swimming community to discover  why we call 1650 yards a mile.

The first person I spoke with was Glenn Schroeder, a former age-group swim coach in Nevada.

TSC: Glenn, why are there only 1650 yards in a swimming mile?

Glenn: It probably has to do with those neat lap counters they use. If they went to 1750 yards, they’d have to add a 7 to the 10’s digit

TSC: But which is older, lap counters or the 1650?

Glenn: You got me there.

TSC:  And why not go to a  1700. That would still only require a 6.

Glenn: Because “1700” sounds too long.

I didn’t buy it, so I moved on. I started looking through results of old Olympics, and discovered that only one Olympics ever was swum in yards, which were the 1904 Olympics in St. Louis. The 1904 games included a mile swim that was a true mile. Unfortunately, the 1904 Olympics were swum in an artifical lake, rather than a pool, and as such was no help.

But if open-water swimming has a true mile (they still do today), then why can’t pool swimming get any closer? A 1750 or 1800 yard swim would be much closer. A key clue comes in looking through historical swimming records, such as these pool records from the North Sydney Olympic Pool.

Swimming pools in the United States, Australia, and the UK were often built in 55 yard distances in the early and middle part of the 20th century. Similar to 440-yard tracks, 55 yard pools were used because races could be made in convenient, even proportions of  a mile (880 yard half mile, 1760 yard mile, etc.). Looking through the records above, you’ll notice that there is both a record for the 1760 freestyle and the 1650 freestyle. That’s because, for a long time, the official mile distance in the United States was 1760 yards.

But then things changed.

The AAU (predecessors to USA-Swimming) relented and changed their long course meets from 55-yards to 50-meters in order to better prepare their swimmers for the Olympics. But the United States held firm with it’s short course pool at 25 yards, instead of the international meters. Large organizations training Olympians could afford the expense of converting their pools to 50 meters (which is about a foot short of a 55 yard pool) or building new ones, but to the tens of thousands of neighborhood and high school pools, this cost would’ve been prohibitive.

Henry Taylor of the UK, who was the first Olympic winner of the 1500m swim in 1908.

In international swimming, beginning with the 1908 Olympics (which were actually swum in a massive 100m pool built inside of a track oval), the 1500m freestyle was a logical standard distance event. At 1.5 kilometers, it made sense to the other 95% of the world that uses the metric system, and sporting fans were already familiar with the 1500m run that was a standard distance in the more familiar track & field discipline.

Once the United States switched to a system of 50-meter long course and 25-yard short course pools, they had to find a way to keep the two systems as similar as possible, so that when it’s athletes did travel to international competitions, they weren’t at too much of a disadvantage.

And this is where the 1650 freestyle came from. The closest emulation of a 1500m swim in a 25-yard pool is the 1650 freestyle (to be precise, 1500m=1640 yards, 1 foot, and 3.12 inches, give or take), so the AAU likely decided to replace the true old-fashioned mile with a newer, more worldly distance. People were so used to calling this distance the “mile” that the name lived on. So there you have it. It was that crazy Imperial system after all.

[Update: We got a great suggestion from one of our readers that the 66 lap swim was a result of Phillips 66's major USA-Swimming sponsorship. Although it was an intriguing and amusing idea, from a marketing standpoint, the 1650 is not really a glamor event.

Our research shows that the Phillips 66 sponsorship of American Swimming started in 1973, whereas the earliest incarnation of a 1650 we can find is in 1959 in Australia. But that's the kind of creativity we like here at the Swimmers Circle Mysteries!]

Now, as to whether USA-Swimming, the NFHS, and the NCAA should switch from 25 yards to 25 meter short course swimming is a whole different discussion for a different time. But for now, chalk this one up as a mystery solved.

    So you swim a standard 1500m, but call it 1650yds even though it’s nearer 1640yds and then pretend it’s a mile. That’s hilarious!

      In a nutshell, yep! The real question is whether we right it off to crazy Americans, or crazy swimmers whose brains have been eaten away by all of the chlorine!

    I actually wondered the same thing many years ago and I was told (don’t know if there is any validity to this, but it sure does sound believable) that Phillips 66 was the major swim sponsor and they went with 66 laps to tie in with the company name, very smooth advertising, the phillips 66 mile…….hmmmmm? what do ya think??

      Ha! That’s a hell of a theory! Phillips started sponsoring USA-Swimming in 1973, however, and we know that the 1650 yard swim started popping up at least as early as 1959 in Australia, so probably no conspiracy. But great thinking!

    I’m surprised that everyone challenges the 1650 short course mile, but not the 1500 long course mile! If we wanted to be closer to a mile in the US, we’d do a 1600 long course mile, and a 1750 short course mile. It’s either got something to do with the metric to standard conversion, or the fact that you have to do so many flipturns that it equals out compared to open water distances.

    [...] per yard is 1650 yards, or 66 lengths of a 25 yard pool.  There is a good explanation for this on The Swimmers Circle [...]

    [...] explanation for this was not easy. The most “thorough” answer I could find seems to be this blog post, but reading and re-reading it, there is information missing that makes it almost impossible to [...]

    My Y requires 72 lengths instead of the 66 for each mile, if you are tracking for their 100 mile club. Or 200 mile club.
