Welcome to Ironbourne

The organisers of the award winning Eastbourne Triathlon present the UK's newest (and probably fastest) long distance triathlon.

Swim Routes

The swim start is set to be one of the most iconic starts on the triathlon calendar, with a jump off the end of Eastbourne's historic pier!

Middle Distance

The run will be 2 laps of a fast and mostly flat 10.5km seafront route.



When and Where?

The swim will start from the end of Eastbourne Pier at 6am on Sunday 18th July 2021. Bike check-in, registration and race briefing will be at the Western Lawns on the Saturday.

What are the cut-off times?

We will be using the same cut off times used at most long distance events:
Swim: 2 hours 20 minutes + a further 10 minutes from the swim cut off to start the bike.
Bike: 10 hours 30 minutes (after you cross the swim start timing mat) + a further 10 minutes from the bike cut off to start the run. Run: 17 hours (after you cross the swim start timing mat).

I'm nervous about that swim start… how high is the jump?

Don't worry! There's a platform at the end of the pier that will only be a foot or two above water level. It's not a big jump.

Are the roads closed for the bike route?

No, the roads will be open to traffic. Unfortunately, the cost of closing roads means that only the very big branded races can afford to close roads.

What are the roads like?

The bike consists of a 12 mile section out of Eastbourne, followed by twice around a 40 mile loop and then a final 20 miles section back to Eastbourne. The first section and the first half of the loop is on fairly big roads including some sections of duel carriageway coming out of Eastbourne, however these sections will be quiet on a Sunday morning. The second part of the route is on quiet country lanes followed by the final section back to Eastbourne via Beachy Head.
