The 2018 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 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!

Live Streaming (TV) Coverage:

Live (internet-based) TV coverage of the 2018 IRONMAN World Championship for global viewers will be available on Facebook Watch via

Race day live coverage is due to begin from at 6:10 a.m. local time (5:10 p.m. UK time) on Saturday 13th October, building up to the start of the Pro races at 6:35 a.m. local time (5:35 p.m. UK time).

In addition, a ‘live body marking show” will also be broadcast from 4:40 a.m. to 5:40 a.m. local time (3:40 p.m. to 4:40 p.m. UK time), hosted by Greg Welch, Paula Newby-Fraser, Michael Lovato and Paul Kaye, again building up towards the start of the race.

IRONMAN World Championship 2018

“Producing this year’s event is Amaury Sport Organisation (A.S.O.), a best-in-class television production company that is highly experienced in Live coverage of endurance sports events such as the Tour de France to audiences around the world. The live-action will include more cameras than ever before and aerial imagery that will put viewers into the heart of the race, showcasing the amazing beauty and grueling conditions that the island of Hawai’i is known for.”

Live Tracking and Results:

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.
