North American Ironman DNF Rates: Finishers and DNF by Race
The average triathlete spend months, if not years, preparing to compete in an Ironman Triathlon, to finish the 2.4 mile swim, 112 mile bike ride and 26.2 mile marathon in less than 17 hours. In a typical North American Ironman, nearly 95% of those who start will ultimately finish the race. And it's interesting to note that even with a world-class field, Kona has a 7% DNF rate.
In 2010, two races deviated from this norm. The Inaugural Ironman St. George was far tougher than expected, leading to a 14% DNF on a very difficult course (we estimate 18% in 2011). In extreme heat, Ironman Louisville Kentucky had 16% DNF, though in previous years, the rate has been in the 5% to 7% range.

Toughest/Easiest Ironman Triathlon 26.2 Mile Marathon: Comparing 25 Run Courses
The idea of running 26.2 miles after finishing a 2.4-mile swim and 112-mile bike ride is daunting, to say the least. Trying to identify which race appears to have an easier or tougher marathon is a little easier. Above are average times for the most recent marathons in 25 of the world's leading Ironman triathlons. [Also see Average Ironman Bike Course Splits and Average Ironman Finish Times]
The wild card to consider when looking at these times: the degree of difficulty on the bike course. A 5+ hour marathon on the St. George course probably has a lot to do with it's toughest 7-hour bike ride. China's course features the toughest marathon; however, the race will be on a new course in 2011.
Austria and New Zealand have comparable, relatively easier bike courses, and as a result, legs may be fresher to run faster marathons. More interesting is to note that Florida, Arizona and Lake Placid marathons are nearly identical. Madison as the toughest marathon? Having raced 8 of these events personally, I'd agree.

Ironman Texas 2013 Results Analysis
See 2014 Results: Ironman Texas 2014 Results Analysis
------------------------------
Triathletes who have finished Ironman Texas in the past will tell you it's one of the tougher races on the Ironman calendar, and the 2013 event more than proved the point. Nearly 2900 athletes registered to compete, and after 13% DNS, and a remarkable 17%, or 408, DNF, the remaining 2,046 finishers took an average 13 hours and 40 minutes to complete the race. The result was 22 minutes longer than the 13:18 average finish time in 2012 and more than an hour slower than the average time to finish an Ironman:12:35. The main differences between Ironman Texas 2012 and 2013 were an additional 11 minutes on the bike, and a marathon took an additional 18 minutes -- 5 hours and 35 minutes.

| Typically we see the bike split consume 50% of an Ironman finish time, with 35% spent on the run. Not this year: 46% on the bike, and a staggering 41% on the run. |
These DNF rates are not too dissimilar than those at Ironman St. George 2012: 19%
 |
| Athletes whose bike/run time landed in the upper left hand corner -- they went after a faster bike split, left too much energy on the bike course, and suffered mightily on the run. The share of athletes in that upper left hand corner is among the highest we've observed. At the same time, note the lower right hand corner; that space is reserved for those who held back on the bike, with extra energy to run a better marathon. |

Ironman South Africa Results Analysis
How tough were conditions at Ironman South Africa this year? Short answer: second slowest average Ironman finish times we've ever seen, 13:43. Only Ironman St. George has proved tougher in our Top 25 Toughest Ironman Rankings. But this year's Ironman South Africa was a one-time aberration; in 2011, the average finish time was 12:53, more typical of IM SA results.
What made the 2012 race 50 minutes slower? To begin, the swim -- which came close to being canceled -- resulted in an average split of 1:33. It's by far the slowest we've ever seen in an Ironman, a full 10+ minutes higher than the typical average. And things didn't get any easier on the bike course, where triathletes averaged 7 hours to complete the 112 mile bike course. After facing crushing difficulty on the swim and bike courses, competitors finally caught a break, settling into a relatively normal 4:53 marathon.
Those who finished battled through a decidedly tough day that forced about 9% of swimmers to DNF after the swim, and another 4% DNF after the bike. Those who made it across the line did more than just finish an Ironman. They battled through one of the toughest races they'll ever compete in, they never gave up, and proved that overcoming nearly impossible obstacles -- unforgiving conditions -- is truly possible.

Unfinished Business in Boston: Projecting Non-Finishers' Finish Times
It's about time. Literally. It's about declaring projected finish times for the thousands of Boston Marathon runners who were not allowed to finish after the terrible tragedy suspended the race.
Three weeks have passed since the tragedy, and yet there is no resolution for those thousands who have every right to declare themselves Boston Finishers, given the circumstances of the day. Time for closure. Time to define your projected finish time. The BAA's resolution isn't ready yet, which is reasonable, given the myriad of other issues they face.
Until then, it's time to step up with projected finish times, and we've taken on the assignment (unofficially). We ran the numbers, slicing and dicing the data every which way (see notes on Methodology, below), and after hours and hours of detailed analysis, I'll get to the punchline.
Projecting Your Boston Marathon 2013 Finish Time
What might your finish time have been? It may be as simple as this:
- If you were stopped after 35k, your effective finish time may = 35k time multiplied by 1.23
- If you had crossed the 40k, your effective finish time could = 40k time multiplied by 1.06
But: One exception will be the runners who went out too fast, too early, and had hit the wall, slowing to a crawl. See our Correlation Between First and Second Half Split Times to gauge if you fit in that group.
Will the BAA's resolution be different? It very well could be. We don't know what direction they will go. But one thing is clear: our analysis here is unofficial; BAA's will be the official resolution.
Methodology
Background: our perspective on this topic comes from several dimensions. We know the course intimately; 13 consecutive Boston finishes. We've been presenting in-depth coverage of the Boston Marathon for years, see www.RaceBoston.com. We've developed and posted dozens of analytics and diagnostics about Boston; see our Stats/Results/Analysis archive for more than 200 posts analyzing top marathon and triathlon events. We're not new to projecting finish times based on incomplete data; see many examples in our Race Statistics/Results Analysis archives. Most recently, we projected finish times of the new Ironman 70.3 St. George within 1% of actual.]
We noted the multipliers above were 'deceptively simple' because it took a great deal of work to confidently calculate the appropriate value.
Our approach is illustrated in an example of our analysis of all Illinois finishers in the 50-54 age group. This included 53 men, 19 women. We did extensive analysis of this sampling of runners, tabulating their 5k splits from start to finish, comparing an contrasting splits from sub-3 hour finishers to 4+ hour runners, from Boston re-qualifiers to those who, well, didn't come close to requalifying.
See data below, from drill-down detail for each finisher, up to average splits as a percent of total, which we used to calculate the 35k and 40k multipliers.

Kona Qualifying Times Analysis 2010-2011
Our current, comprehensive Kona Qualifying Times Analysis for 25 Ironman races defined the minimum finishing times to qualify for the 2010 Ironman World Championship.
We're updating the analysis for the 2010-2011 season, and will be featuring qualifying times by race here, as results become available. We're also comparing qualifying times by race and age group, year-over-year.
The results are not surprising. Each year it seems the challenge to qualify for Kona becomes more difficult. Two reasons: more competition and fewer slots per race in many cases.
We've compared Kona qualifying times for many of the major Ironman races -- France, Florida, St. George, Western Australia, New Zealand and Wisconsin, Cozumel -- by age group. Harder? Yes, in most cases. But look closely: Cozumel's race was dramatically faster overall in 2010, as were the qualifying times, and sometimes the last slot rolls far deeper than you might expect. Note the M30-34 time at Ironman Austria in 2010, for example.

Number of Annual Ironman Triathlon Finishers
By Raymond Britt -- In the last twelve months, more than 41,000 triathletes finished 25 Ironman Triathlons. Each finisher met the daunting challenge of a 2.4 mile swim, a 112 mile bike and a 26.2 mile marathon. Of the finishers, nearly 1600 qualified to compete in the 2010 Ironman Triathlon World Championship.
If you add non-Ironman branded Ironman distance races to the mix, such as Challenge Roth, we estimate a global total of 50,000 finishers. While there is no such thing as an easy Ironman, some were clearly more difficult than others. Our data shows between 5% and 7% DNF rates for most events. Ironman St. George and Louisville, however, posed extraordinary difficulty in 2010; each had DNF rates around 15%. See RunTri's Ranking of 25 Toughest Ironman Races for details.

Entering an Ironman Race: When is a Race Sold Out?
For races in the US in 2010, about 3000 was the limit. But the definition of 'Sold Out' has increased remarkably over the years (with the exception of 2008). And Canada's on its way to 3400 for 2011.
Many of the most popular Ironman races in North America are deemed 'Sold Out' the same day registration opens. How many entrants can register for 'General Entry'? How many additional Foundation Entries? The numbers aren't made public, but we've done the analysis. Our estimate: roughly 2700 General, 300 Foundation Entries, around 3000 total. Canada is the exception for 2011, so far.
Combined General + Foundation Entries seem to increase by 100 to 200 athletes each year. In 2005, races were Sold Out with about 2200 to 2400 entrants. By 2010, up to 3000 total entries in a race seemed to be the limit for most races.
Toughest/Easiest Ironman Swim Course: Comparing 25 Ironman Races
There are fantastic swim courses on the worldwide ironman circuit. Among my favorites are Kona, New Zealand and Florida. I've completed the Ironman swim in 29 races, and while I'm not a great swimmer, my swim times have sometimes varied from course to course more than expected.
So I did an analysis of 100,000 Ironman finishers to try to answer the question: Is it possible that the degree of difficulty swimming 2.4 miles differs by location?
The data says yes, if you assume that all swim courses are measured reasonably accurately. Here's how they compare on average. Then continue reading: there's much more to the story.

The data says yes, if you assume that all swim courses are measured reasonably accurately. Here's how they compare on average. Then continue reading: there's much more to the story.
Factors that impact average swim times can range from a very tight swimming venue, very rough open water, or speedy currents. And these factors can have dramatic impacts.
In the slightly dated chart above (newer one to be posted soon) comparing 25 Ironman swims, Cozumel is shown as one of the fastest at an average 1:08 split. However, at Ironman Cozumel 2012, the average time was 1:28:59, see chart below. Reports from Cozumel swimmers indicated a particularly challenge last section of the swim, and some athletes described their times as 10-15 minutes slower than they expected.
And swimmers at the Ironman US Championship 2012 in New York City cruised with the current to an average 51 minute swim split.
