Think you know Ironman racing? Predict races at im-betting.com

Just a quick post to let you know about an exciting new project I’m starting:

Luke Dragstra and I are teaming up to bring you im-betting.com. Before a big Ironman race, you can submit your bets, and the best bets will win some cool prices. Here are some more details:

  • The first race you can submit bets will be IM Melbourne on March 24th. We’re also targeting IM Germany, possibly some more summer races and of course Kona.
  • You submit the top 10 for the men and the top 6 for the women.
  • You’ll earn points if you pick the right winner, athletes on the podium and within the top 10 or top 6.
  • We plan to have prices for the overall winner, the best men’s and women’s picks and a random drawing.
  • Luke has already managed to get a Carbon Wheelset from Planet X and some cool tri clothing from Magic Sportfood for the Melbourne picks.
  • Submitting a bet is free, so this is a great chance to win an attractive price.

I’m busy implementing the bet submission page, but you can already leave your email on im-betting.com and we’ll notify once you can submit your bets. IM Melbourne is shaping up to have a great field, so you should start thinking about your picks as soon as possible. Of course I’ll continue to provide my statistical predictions for the race, so readers of trirating.com should have an advantage!

IM New Zealand 2013 – Analyzing Results

My focus of the first big weekend of Triathlon racing was on IM New Zealand, even if it happened in the middle of the night for me. (The other races in Abu Dhabi and ‘Escape from Alcatraz’ sounded great as well, but I’m mainly interested in IM-distance racing.)

Conditions on race day were typical for New Zealand, the adjustment of 3:30 was in line with the newest course rating of 4:07.

Male Race Results

The big question for the men’s race was if Cameron Brown could hold on to his 10-time winning streak of full Ironman races in New Zealand. (The only times he was beaten was when the race had to be shortened.) He delivered a solid performance, even if he was more than ten minutes slower than his predicted time. The title stayed in New Zealand – with Ironman rookie Bevan Docherty winning with a  course-record performance. (Not only did he better Cam’s overall record but also Torbjorn Sindballe’s bike record.) He’s joining the ranks of recent IM-rookie-winners – Andy Starykowicz in Florida, Nils Frommhold in Arizona and Ivan Rana in Cozumel. Seems that the top IM rankings will change a bit this year!

Second place was captured by Marko Albert with a smart race that allowed him to post an even better run split than Cam Brown. (I almost feel that Cam was holding a bit back for Melbourne when it was clear that he wouldn’t be able to improve on his third place. Something for a more detailed analysis!)

Female Race Results

On the women’s side, Meredith Kessler “defended” her 2012 title. (She said herself that her win in the shortened 2012 had a little asterisk to it, and now she captured the title for real.) Second place Gina Crawford was able to claw a few minutes back on the run, but Meredith was leading the race by eight minutes after the bike. Candice Hammond posted the fastest run split of the day and placed third.

IM New Zealand 2013 – How the race might unfold

At the end of last year I extended my ratings to the individual disciplines, so you get a better picture of where each athlete’s strengths and weaknesses are. This also allows me to get a more detailed look at how the race might unfold. I think that the graphs give you good picture of what a “typical” race between these athletes is going to look like – and I hope that you will also be able to quickly spot if an athlete is doing much better (or worse) than what could be expected. Of course, there is still a lot of room left for speculation: Is athlete A going too fast on the bike (so he will blow up on the run – think Marino in Kona)? Athlete B is a great runner, but can she can afford to give up that much time on the bike (for example, Rinnie)?

A (little) qualifier: Of course, this is just based on “pure” numbers. This does not take “race dynamics” into account. I’m pretty sure that there will be little groups during the swim and bike and that the athletes in these groups will finish closer together than the pure numbers indicate. Also, there is no (statistically valid) way that I can predict the performance of the new IM athletes – therefore they are not included in the graphs. Especially the performance of Bevan Docherty is offering a lot of room for speculation.

Men’s Race

With the above qualifiers, here’s how I think the men’s race is probably going to unfold:

IMNZ Men Prediction

The graph shows how much behind the race leader each athlete is going to be. (A lot of inspiration come from Russel Cox’s post-race posts showing how a race did unfold using the IMLive data, e.g. for Arizona 2012 or Cozumel 2012.)

Here are a few highlights:

  • Marko Albert will probably lead after the swim. Terenzo and Balazs Csoke won’t be too far behind, maybe they will form a group to properly distance Cam Brown who will be 2-3 minutes behind. All the other Pros will be around 10 minutes back.
  • The field will take about 60k on the bike to sort things out. Cam will probably take the lead by then – but again race dynamics might come into play and Terenzo and others may try to stay with him.
  • Of the top athletes after the bike Balazs has the slowest run rating (3:27, and therefore will probably loose a few spots). But his run results have been pretty mixed and his last run was a 3:07 in Austria), so he may be able to surprise. Other than that, the run could turn out to be pretty boring – the graph shows that only the race for 3rd place may be close.

Women’s Race

Here’s the corresponding graph for the women’s race in New Zealand:

IMNZWomen2013

The women’s field is much smaller, but it will probably be a bit more exciting towards the end:

  • Meredith Kessler will lead after the swim and is probably going to extend her lead over Gina Crawford on the bike.
  • Gina is the best runner in the field, based on the numbers she will take the lead just before the 30k mark. However, with a projected winning margin of just around two minutes anything can happen on race day.
  • Carrie Lester and Candice Hammond won’t be too far behind, so if Gina and/or Meredith run into problems, they’ll be ready. Even with the smaller women’s field, I still have four athletes within 10 minutes!

IM New Zealand 2013 – Predictions (Updated)

Update: I goofed up importing the participants, so I missed a few athletes. The most notable athlete is Meredith Kessler, who clearly changes the women’s race. Sorry, MBK!

TOP 3 from 2011

Last year, the race couldn’t occur as planned: On Saturday it was impossible to have a race, so the race haas to be moved to Sunday and shortened to a 70.3. This race was won by Marino Vanhoenacker and Meredith Kessler.

Here are the results from the last “full” Ironman in New Zealand from 2011:

Winning Odds

Male Race Participants

Based on his previous results, Cam Brown is the clear favorite, but the question “Is he to old to win another one?” always comes up for him in Taupo. For fun, here is a “different” photo of Brown, Cameron:

BrownCameron

Cam’s biggest threats come from two countrymen Terenzo Bozzone (back from injury and a DNS in Auckland after smashing into a car door) and Bevan Docherty (moving up from ITU and starting in his first full Ironman):

  • Cameron Brown: 62% (1-1)
  • Terenzo Bozzone: 14% (6-1)
  • Courtney Ogden: 8% (12-1)
  • Marko Albert: 7% (13-1)
  • Scott Defilippis: 6% (15-1)

Female Race Participants

Now that I’m correctly including Meredith Kessler, the women’s race is much closer. Gina Crawford is still my top pick, her rating is a little bit better, and she is a previous winner in New Zealand. It’ll be an exciting run in Taupo:

  • Gina Crawford: 44% (1-1)
  • Meredith Kessler: 39% (2-1)
  • Carrie Lester: 13% (7-1)
  • Candice Hammond: 3% (29-1)
