“The majority of people are having a rough time,” said Jan Frodeno when we interviewed him after his finish at the 2023 men’s Ironman World Championship in Nice. Frodeno truthfully captured how difficult it is to race any professional Ironman race, much less one held in a brand-new venue for the World Championships that is as demanding as any race course ever seen.
The Nice Men’s Ironman World Championship began with 55 athletes who were lucky enough to qualify, with 46 of those athletes initially set to start. Then, due to many of the same reasons that most of us age-groupers experience – illness, injury, issues with gear – six athletes weren’t able to compete (including pre-race favorite Daniel Baekegard). That left just 40 athletes left to toe the start line and clear all the incoming hurdles ahead in Nice: the mountains, the heat, the deep competition, and perhaps the biggest one: Lady Luck herself.
Last year’s Kona race saw a 14% DNF rate from the 51 professional men who toed the line. Before that, in the only other occasion where the World Champs was outside of Kona – St. George – it was a staggering 29%. This year, with all 8,000 feet of elevation gain on the bike accounted for, eight athletes, or 20% of the field were left to make the dreaded black and white Instagram post, sharing their pain of not making it to the end.
Make no mistake: It is a remarkable, brave, and life-consuming achievement just to make it to the start line of the World Championships. But just like we all have bad days at the office, every professional athlete has an off day at some point – oftentimes to no fault of their own. It just happened to be that day in Nice for these eight athletes.
Ironman World Championships 2023 Race Recaps:
Following a career-best performance at the PTO Asian Open in Singapore and a second place ahead of the great Jan Frodeno at Ironman Hamburg, Belgium’s Pieter Heemeryck seemed poised for a breakthrough World Championship result. It was surprising, then, to see him falter in Nice, especially considering his strength across the three disciplines.

Hogenhaug was atop the all-new BMC Speedmachine released at this year’s event, designed in conjunction with Red Bull’s F1 team with hopes of being the fastest TT bike ever. He certainly put in the effort on the bike, but – as we see all too often – he paid for it on the run. His run was looking solid, holding around 6 minutes per mile, but perhaps that was too fast following the extra time on the bike (around an hour more than this athlete is used to thanks to the climbing). Like a few other names on this list, the day ended during the marathon, brutally close to the finish line.
Another powerhouse on the bike found himself on the wrong side of the mountain as the race heated up. With a slower time than the Kiwi would have hoped to complete the 112-mile loop, Phillips fell out of contention, only for things to get worse on the run. Despite exiting T2 at a good pace, he disappeared off the course abruptly after the eight mile mark. It has been a successful year for Phillips with six top-five results this year including two wins, but this setback following his DNF at the Asian Open will be tough to swallow. Thankfully, it’s about that time for the Southern-Hemisphere athletes to call their seasons complete, and he will most likely head home for some much needed R&R.

The Ironman Brazil runner-up this year survived the Nice climbs – barely. He had one of the slowest times for the bike course, suffering for an arduous five and a half hours. The 37 year-old Olympian decided to pull the plug after that effort. (Could you imagine surviving racing up those mountains for that long and trying to race a marathon afterwards?) Colluci will surely be back for more, as his career best-performance as was at Challenge Roth just last year, suggesting there is still plenty more to see from Colluci.
One special shout-out needs to a legend of the sport: 42-year-old Olympian Brent McMahon of Canada, who – despite being listed on the PTO as a DNF – clung on with all of his might to finish the marathon after 11 agonizing hours out on the course. After what he called “the toughest, longest day” of his career, he proudly displayed the finisher’s shirt in his Instagram story.
