As soon as most people sign up to an event, the first question on their mind will be “What’s a good IRONMAN time?”. They want a target to work towards, and often want to avoid feeling embarrassed.
Before we kick off I want to reassure you something. Any finish is a good IRONMAN time. You will have successfully swam 3.8KM in open water, cycled for 180KM and ran a marathon at the end. That’s incredible, and any finish is a good result.
However, this doesn’t answer your question. If you want a good finish time, what does that look like? Let’s break it down by discipline.
What is a good IRONMAN swim time?
The swim is the discipline which strikes fear into the heart of most triathletes. Some will blitz round the 3.8KM in under an hour while others will come very close to, or miss the 2:20 cutoff.
The average IRONMAN swim time is somewhere between 1:20 and 1:30. With good coaching and enough training, most people are capable of going under 90 minutes. Those who are older or who have disabilities might take longer, but the 2:20 cutoff is very generous, you just need to commit to your training.
Swimming over 90 minutes is not a failure by any means, an IRONMAN is a very long day, and an extra 10-15 minutes on the swim is nothing to be ashamed of. Remember, every IRONMAN finish is impressive.
What is a good time for the IRONMAN bike?
Over the 70.23 distance, the three hour mark is a solid target to aim for over the bike, which will require you to average 30KPH. For a fit cyclist this won’t be overly challenging to hold on the flat, but to average this over the entirety of the 90KM including corners and hills is fairly impressive.
Over the IRONMAN, should we be aiming for six hours then? I would say seven hours is a more realistic target. Remember, we still have a marathon to run at the end of the ride! If you come in under seven hours that’s an enormous boost, but coming in over seven hours is certainly nothing to be ashamed of, especially over hillier courses.
What is a good time for the IRONMAN marathon?
The soundtrack of an IRONMAN marathon is the beeping of Garmin watches telling athletes they are running below their pace target. They set themselves a target which they planned to hold over the marathon, but everything is falling apart on them now.
It could be that they pushed too hard on the bike, it could be they just don’t have the aerobic fitness, or they are suffering from digestive distress. There is a multitude of reasons things can, and probably will go wrong for you on the run.
The IRONMAN marathon is a war of attrition, and even if you are an experienced marathon runner, it will push you to your limit, mentally and physically.
It’s a fairly modest finish time by marathon standards, but I would say four hours is a good IRONMAN marathon time.
Adding it all up
This is an incredibly rough calculation, but if we take a 90 minute swim, seven hour bike and four hour marathon, and add on 15 minutes for transitions, that gives us a time of 12:45.
Personally, I would say that anything between 12-14 hours is a good finish time for an IRONMAN. Under 12 is good, and under 10 is elite.
This isn’t to say that anything over 14 hours is embarrassing by any means. You still finished an IRONMAN, but people love a target to aim for, so ducking under 14 hours can be a goal worth pursuing.
This doesn’t take into account the course, your age, potential disability, weather conditions or any other number of variables. If you want to find what a good time for a specific course is, I recommend you look at the results from previous editions of your event (or a similar event) to see what the average finish time was for athletes in your age group, and set yourself a target based off of that.
There is one thing I can guarantee though, you won’t be able to put in a time you’re proud of without a structured approach.
