Each December, we look back on the stories that resonated most in the past 365 days.

As we look back on the past year, one thing is for certain – 2019 was one hell of a year for triathlon. In only 365 days, we saw everything from jaw-dropping performances to insane new gear set to change the way we swim, bike, and run. 

Before we turn our attention to 2020 and all the big stories ahead (Olympics! Super League radness! New Ironman and 70.3 courses!), here’s a look back at our most popular stories of 2019.

#20: Ask Chris: What’s The Best Triathlon Watch?

In this breakdown by gear editor Chris Foster, we showcase some the best triathlon watches in a wide range of prices—whether you want ultra simple, like the Timex Ironman, or something that could potentially drive your Tesla remotely (with a future software update, of course).

#19: Want to Race the Fastest Ironman Courses? You’ll Have to Travel.

When it comes to long-course race planning, course selection is everything – which may explain why so many triathletes google “easy Ironman courses” or “fastest Ironman course.” We compiled the fastest (and slowest) average finishing times at Ironman and 70.3 races, and the top races were surprising to many readers. 

#18: Opinion: The Triathletes in the Tokyo Test Event Deserved to Get DQ’d

At the Tokyo test event for the 2020 Olympic Triathlon, Brits Jessica Learmonth and Georgia Taylor-Brown dominated the women’s race and crossed the finish line together, holding hands. Though the gesture was lauded as a sign of sportsmanship, the ITU disqualified the athletes for violating a “contrived tie situation” rule. In this op-ed, columnist Kelly O’Mara explains why the ITU was right to enforce the rule.

Researchers have spent hundreds of hours trying to understand what is causing deaths in triathlon swims. Now, now beginning to better understand one possible reason why: SIPE, or Swimming Induced Pulmonary Edema.

#16: Cervelo Unveils New P3x

In a move that surprised many, Cervelo unveiled not one, but two new bikes in 2019. The P5x and P3x were exciting developments for the ever-popular tri bike brand.

#15: This Endurance-Focused Strength Routine Takes Only 30 Minutes

There are only so many hours in the day, and honestly? We’d rather ride our bikes than hit the gym. Still, it’s no secret that strength work is critical for triathletes. That’s why it came as no surprise that this quick strength session was a hit with our readers – the shorter the workout, the quicker we can get back to swim-bike-run.

#14: Midsole Cleat Placement: Should All Triathletes Be Doing It?

In the same way that tri bikes are set up differently than cycling time-trial bikes, it might be time to rethink other aspects of the traditional cycling setup with an unconventional modification—mounting your cycling shoes’ cleats right in the middle of your feet (or as far back as you can), not under the ball of the foot.

#13: How I Used the Rower to Train for an Ultraman

In this article, Jack Nunn shared how and why he did 80 percent of his Ultraman training on a rowing machine. This got a lot of clicks and a lot of comments on social media, both from purists who were upset about circumventing traditional swim-bike-run plans and curious triathletes who wanted to know where they could buy a rower.

#9: Why I Quit Masters Swimming

This essay by Marshall Ellis, in which he describes his Masters swim experience as “lost without a map in Dante’s circles of hell,” was both loved and loathed by readers, who fiercely debated the role of Masters swimming groups in the training plan of triathletes.

#8: Lucy Charles-Barclay is Rewriting the Rules of Ironman Racing

“Gone are the days when the swim was simply the prelude to a bike-run battle,” writes contributor Brad Culp, “now the race truly starts at the cannon, thanks to Lucy Charles-Barclay.”

#7: The Best Triathlon Gear of 2019

Our annual triathlete Buyer’s Guide featured 170 items, but only 21 earned the designation of “Best in Class.” It’s a distinction we don’t make randomly – to compile the Buyer’s Guide, editors and contributors undertake hours of swim-bike-run testing (it’s a tough job, but we’re happy to do it).

#6: 6 Things Triathlon Coaches Secretly Hate

Do you ever wonder if you’re pissing off your coach? These coaches say you probably are – and it’s likely because of one of these offenses. Perhaps this might inspire a new year’s resolution or two?

#5: 5 of the Best Iron-Distance Races for First-Timers
