IRONMAN World Championship 2019

THE DETAILS (Everything you need to know…)

The 2019 IRONMAN World Championship, as in previous years, will be available – free of charge – to follow via live video, text and online timing/tracker updates.

We have compiled here – with DETAILED UK TIMINGS to make it easy for many of our readers – an extended and comprehensive schedule of key race events to provide approximate times of some of the notable moments during the coverage. You can now plan your viewing around important things like dinner or a few pints at the local… but still know what time to get back to see the marathon start!

*** These times have been fully updated ahead of the 2019 race ***

The 2018 races (MEN | WOMEN) saw all-time course records courtesy of fine racing in very favourable conditions. In addition to that, comprehensive changes have been made to the start times for both Pro and Age-Group athletes, to help reduce athlete density on the bike course.

All of that has been factored into our detailed and revised schedule of events below.


Live (internet-based) TV coverage of the 2019 IRONMAN World Championship for global viewers will be available on Facebook Watch via

Race day live coverage is due to begin from around 6:10 a.m. local time (5:10 p.m. UK time) –  on Saturday 13th October, in the lead up to the start of the Pro races at 6:25 a.m. local time (5:25 p.m. UK time).

In addition, a ‘live body marking show” will also be broadcast from approx. 4:25 a.m. to 5:40 a.m. local time (3:25 p.m. to 4:40 p.m. UK time), again building up towards the start of the race with some pre-race chat with some of the Pro athletes.


Depending on your equipment, you can watch the IRONMAN ‘Facebook’ broadcasts directly on your TV – potentially without the need for a computer / tablet.

If you have a Samsung Smart TV for example and a good internet connection, then you can download the Facebook Watch TV App and watch in full widescreen. I’ve used this many times and, for the vast majority of the time, it has worked fantastically. Streaming devices such as Apple TV of Chromecast will also work well in this regard.

For more details on compatible devices and TVs and/or how to stream, then THIS ARTICLE is a great place to start to understand what to do.

FACEBOOK VIDEO LINKS (There are several…)

Yes, one (slightly…) frustrating part of the Facebook streaming process, is that because of restrictions on live video length, you will have switch video streams during the race. This applies whether you are watching on your computer / laptop / tablet through the Facebook page, or directly on your TV through Facebook Watch.

Here are those links:


The best way to keep up to date with tracking athletes – Professional and Age-Group – is by downloading the (free) IRONMAN Tracker app. The app provides timing information, leaderboards and allows you to set notifications for athletes you want to follow, which will update as they pass through what is likely to be approximately 30 timing points on the course. It really does work a treat.

If you don’t have it already, you can download in via the iTunes App Store or via Google Play.
