Ironman Lake Tahoe DNF (Did Not Finish) Rates Analysis: Comparison with Other Ironman Race DNF Rates
 |
| As Featured by Triathlete Magazine Online Edition |
The inaugural Ironman Lake Tahoe 2013 crushed triathletes beyond their wildest expectations, with a record-breaking high average finish time of 14 hours and 6 minutes, easily making it the toughest of the RunTri's Ranking of the Top 30 Toughest Ironman Races.
The venue featured breathtaking scenery, but at the end of the day, the views were not much consolation to the 20% who did not finish the race. Fast Facts:
- Registered Entrants: 2700+
- Did Not Start: 565 (21%)
- Finishers: 1,719
- DNF of Race Starters: 20+%; DNF on Bike: 267 (12%); DNF on Run: 182 (8%)
The stunning results at Ironman Lake Tahoe seemed to have the triathlon community buzzing (thousands of visitors from 800 cities visited our site's analysis, see map above, and interactive map at end of article): Did you hear what happened at Lake Tahoe? Did you hear about the weather? Did you hear about the DNFs?
Ultimately the biggest question seemed to be: How Ironman Lake Tahoe DNF Rates Compare With DNFs at Other Ironman Events?
The answers may surprise you.
- Yes, Ironman Lake Tahoe Was a Punishing Race, and Some Age Groups Suffered More than Others
- Ironman Lake Tahoe's DNF Rate falls far short of the 29% recorded at Ironman St. George in 2012, BUT . . .
- There's No Guarantee that Ironman Lake Tahoe 2014 Will see 20% DNF, Too; Conditions and DNFs Vary by Year.
1. Yes, Ironman Lake Tahoe Was a Punishing Race, and Some Age Groups Suffered More than Others
Let's start with our analysis of Ironman Lake Tahoe's DNFs: overall, by age group, and within age groups, DNF rates on the bike or run.
But when Ironman St. George is eliminated from the comparison, Lake Tahoe's DNF rate is highest. Among other high DNF events, Louisville and Texas don't come close to LT's 20%.
3. There's No Guarantee that Ironman Lake Tahoe 2014 Will see 20% DNF, Too; Conditions and DNFs Vary by Year.
Our Multi-Year Analysis of DNFs Overall (at Ironman Wisconsin) and by Age Groups (at Ironman Lake Placid) clearly illustrate that DNF rates can vary significantly from year to year.

Which leaves a couple of thousand athletes wondering: should I sign up for Ironman Lake Tahoe next year? If you like the area, the course, and are well-prepared, I'd suggest you sign up for this great race.
Worried that next year may see 20% DNF again? Sure, it might happen. But I'd not be surprised to see a different DNF rate, more likely to be lower than higher, based on our Ironman Wisconsin and Iron Lake Placid analysis.
Still on the fence? Final thought -- whether DNF rate is 10%, 15% or 20% -- if it were easy, they wouldn't call it an Ironman. Don't be scared by DNF rates, I'd tell you. Prepare vigorously with expectations to be among the 80% of Finishers.
Go Ahead. Sign up for 2014. Crush the course next time.

------------------------------
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. |

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.

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.
