Kona 2018 Resources

Here is a list of resources for Kona 2018 (race on Saturday, October 13th):

Some posts from other Triathlon media:

  • Tim Heming’s discussion for the British “220 Triathlon” magazine about his Top 10 Kona Predictions for the Men and Women
  • Australian Triathlete’s preview of the Kona contenders and the expected timelines
  • Triathlete USA also has a set of Kona previews: “Can anyone beat Daniela Ryf?” and “Will Patrick Lange Repeat?
  • Talbot Cox has a whole series of videos, e.g. on Sebastian Kienle, Lionel Sanders or Daniela Ryf
  • The schedule for “Breakfast with Bob” (starting Monday) can be found here. (If you have a chance to watch it live, by all means do so – most of the Pros are really friendly and still relaxed.)
  • Ironman will do live shows Tuesday to Friday at 8am Hawaiian time (2pm ET) on their Facebook channel ( That’s also where the race will be shown on Saturday.
  • Talbot Cox has a series of videos in his “Kona 2018” series on YouTube.
  • The Ironwomen podcast has interviews with most of the female Pros on their Facebook page. They will also do live coverage of the race on Saturday focused on the female race.
  • WitsupLogoWitsup and Stef Hanson have a YouTube playlist “Kona Chatter 2018” with the top female Pros.

I’ll add to this list as soon as my friends and I release more information closer to the race!

Announcing the Kona 2017 Rating Report

2017 TitlePage Kona Report 700px

For the 2017 Ironman World Championships in Kona I have released a 120+-page Rating Report with tons of information:

  • Detailed results and analysis of last year’s race
  • Information about the Kona course, top Kona finishers and the current course records
  • The Kona 2017 start list and my predictions and odds for the Pro athletes
  • How the race may unfold and what to watch for when the race is going on
  • Details about each Pro including their input and a lot of photos they have supplied

The Report is available for free, but it would be great if you can support my work before Kona and during the year by donating an amount of your choice, for example the list price of a regular tri magazine (around 7$).

The Kona Rating Report is the ideal information to have when following the Ironman Kona coverage!

Here’s what a couple other triathletes have said about the Report:

Race Posts – Explaining the Types and Data

TriRating’s main feature is data about Ironman-distance races and my analysis of these results. This post describes the different types of race posts and the data in them.

Entry List

This is usually my first post about a specific race. A couple of weeks out there is information about which Professionals have registered for a race. At this point, the list is not final yet – there are still some more athletes that can register, and some athletes that registered may withdraw before race day.

Here’s a sample screenshot:


The list shows the Pros that have entered a race, ordered by their bib number (when already available), their KPR points (if it’s an Ironman® race) or their last name.

The following details are shown:

  • Name: The full name of the athletes (first name and last name )
  • Nation: The nationality of the athlete (sometimes different from the official lists that often show where the athletes is currently residing)
  • KPR points: The total Kona Qualifying points the athlete has accumulated at the time I publish the entry list
  • KPR races: The number of Ironman and 70.3 races that the athlete’s KPR points are coming from. For example, “3+1” for Harry Wiltshire means that he already has three Ironman races and one 70.3 race in his total. (Remember that only up to four races – up to three IMs and up to two 70.3s – can contribute to an athlete’s total.) The points in brackets show the lowest scoring race from each category, so “(235/500)” for Harry mean that his worst IM score is 235 points, and his worst 70.3 score is 500 points – these are scores that could get bumped from the total when he tries to add another race to his total.
Depending on the information available, the Entry List may also show
  • Bib number
  • Age of the athlete on race day
I won’t be publishing entry lists for all races, as not all races make this information available in a timely fashion. Ironman is usually posting Entry Lists roughly four weeks out from a race.


After a race has been closed for entry by Professionals, a start list is posted by the race organizer, typically two weeks before a race. Late entries are possible but pretty rare, late withdrawals are much more common. Also, athletes often register for a number of races within a short time, giving them a back-up race in case something happens in the first race they target.

Here’s a sample seeding (from the female race at IM New Zealand 2017):


This list shows many more details than an entry list:

  • Rank: The expected place of this athlete based on everyone’s previous results (and every athlete on the start list starting and finishing the race) and their corresponding expected time (see below).
  • Bib: The bib number as assigned by the race (if the information in available)
  • Name: The full name of the athlete (first name and last name)
  • Nation: The nationality of the athlete (sometimes different from the official lists that often show where the athletes is currently residing)
  • Expected Time: The time I expect an athlete to finish on the course of the race, based on the athlete’s previous results and how fast or how slow the course is, also favoring results from the course.
    The background color shows who are the fastest athletes (dark red – expected time within 12 minutes of the projected winner) and who are close (lighter red – expected time within 25 minutes).
  • Rating: The weighted average of an athlete’s previous performances. This is more stable than the expected time (i.e. older results are not discounted quite as much) and course-neutral. For example, Yvonne Van Vlerken has a better rating than Meredith Kessler, but as Meredith has performed extremely well in Taupo, her expected time is the fastest.
  • Expected Swim, Bike and Run: Similar to the Expected Time, but broken down for each of the legs and the athlete’s strengths and weaknesses. Again, the background color is used to show the expected fastest athletes in each of the legs.
  • Consistency: The consistency shows how often an athlete has performed to the expected times. The first number (e.g. “60%” for Meredith) indicates how often the athlete was close to the expected time (roughly within 20 minutes), the second number (“+10%”) how often she was faster and the third number (“-30%”) how often she had a sub-par race (including DNFs). The last number, shown in brackets (“(26)”) shows the total number of IM-distance races an athlete has started. You can find a longer discussion of the consistency in this post.
  • Overall: The place the athlete has in the overall rankings. Numbers shown in brackets (e.g. “(52)” for Emma Bilham) indicate where an athlete would be ranked, but that he/she does not currently have a valid rating (requiring one finish within the last year and at least three finishes).

Result Analysis

Once the race has been completed, I publish the results with my analysis of how the athlete performed, usually within a day or two after the race has been held.

Here’s an example from the female race at Challenge Wanaka 2017:


The following details are listed:

  • Rank: The position the athlete finished in the professional race.
  • Name: The full name of the athlete, depending on how the athlete has performed relative to the expected time and the conditions on race, the name is shown in red (more than 3 minutes slower), in green (more than three minutes faster) or black (within three minutes of the expected time).
  • Nation: The nationality of the athlete
  • Swim, Bike and Run: The times for the swim, bike and run legs, again colored according to how well the athlete performed on race day. The background color is used to indicate who had the fastest time in each leg (dark green) and who was close (lighter green).
  • Time: The “clock time” of an athlete’s finish at this race. A “DNF” indicates that the athlete didn’t finish the race, the splits are given as far as the athlete has completed the race.
  • Diff to expected: The difference of the total time of an athlete compared to the expected time (based on the conditions on race day).
  • Prize Money: The prize money the athlete has earned for his finish in the race.

2017 KPR Observer Now Available

2017 Title ThumbI have just released the 2017 edition of the KPR Observer, following Kona qualifying for the Professional athletes.

The Kona Pro Ranking (or KPR for short) is the system used to determine which Professional triathletes qualify for the Ironman World Championships in Kona. The 2017 KPR Observer consists of an Initial Information Package about the KPR and ongoing updates during the season.

The Initial Information Package (delivered at the time of purchase) contains:

  • a description of how the KPR works in qualifying Pros for Kona
  • changes to the 2017 rules and their implications
  • base projections for the men’s and women’s cutoff
  • graphs and descriptions of the current KPR standings

During the season, there will be at least six EMail Updates (and probably ten) about the KPR Standings, who is already in, who is close to qualifying, how many slots are still open and updated estimates of where the cutoffs will occur.

To give you a short glimpse of the material in the KPR Observer, here is a look at the women’s and men’s KPR rankings at the end of the 2016 racing season:

If you want to qualify as a Pro, coach a Pro athlete, write about professional Ironman racing or are otherwise interested in the KPR, this is must-read information! The time you’ll save with the KPR Observer is easily worth the price of 29$ for the full season.

(If you are a Professional athlete looking to qualify for Kona, please send an email to to receive information about a complimentary copy.)
