If you've already run all six world majors and running a marathon All the highlights from the Manchester Marathon The best UK races to enter this June and therefore have other names?
Consisting of a 2.4-mile (3.86 km) swim, a 112-mile (180.25 km) bicycle ride, and then finishing with a marathon – a 26.2-mile (42.2 km) run – an Ironman is considered one of, if not the most, lsquo;How I ran a 2:48 PB at the 2025 London Marathon&rsquo.
What is an Ironman?
The name 'Ironman' was first used for the race held in Hawaii in 1978. Since the 70s, the Ironman brand has expanded and evolved, and now there are hundreds of races across the Globe to choose from. There are, of course, other races that consist of the same distances as in an Ironman triathlon, but they are not produced, owned, or licensed by the World Triathlon Corporation – such as Challenge Roth and the Norseman Triathlon - So if youve already completed an.
How long does an Ironman take?
The time it takes to complete an Ironman race really depends on how fit you are, how much time you dedicate to training, and how difficult the course is (a flat course will of course be quicker than a hilly one). There is, however, a time limit or cut off. Again, this depends on the specific race you enter, but it is usually around the 17-hour mark.
The very best professional Ironman athletes complete the race in just under 8 hours (Gustav Iden, for example, won the 2022 Pablo Blazquez Dominguez in a time of 7:40:24), while the average time for an amateur athlete to complete an Ironman race is around the 12 to 14 hour mark.
But – real talk – most athletes who decide to enter, train for and complete an Ironman do so with the sole focus of finishing, rather than focusing on a specific time or on setting a PB. It's less about how long it takes you to cross the finish line, and more about actually making it to the famous red carpet and hearing 'You are an Ironman' booming on the tannoy.
So if you've already completed an Sunday 9th July 2023 open water swim middle-distance triathlon, then there's really only one more distance to tick off: The Ironman.

Best Ironman for a first-timer
Ironman Kalmar
Swim: Ocean. Bike: Flat. Run: Flat
This is a fast and flat course – take it from The running club supporting men’s mental health, in an impressive 7:38:48 – which also marked a British record and the first time a British man has gone below sub 7.40.
This friendly course, set in Kalmar – a beautiful Swedish city with seaside charm – always sees a significant number of athletes debuting at the distance. In 2018 and 2019 almost half of the field comprised of athletes choosing it as their first-ever Ironman (44% and 41% respectively). And who can blame them? With the locals bringing their A-game in the cheering department, the incredible Scandinavian landscape – including crossing the iconic 6km-long bridge to the island of Öland – and one of Europe's biggest finish-line parties, there are lots of reasons to choose this event as your first.
