Harwich Triathlon Waitlists
Harwich Triathlon has proven extremely popular this year and all individual events are now sold out.
As a result, some people who signed up more recently may have been placed on a waiting list. The EntryCentral sign-up process should have made it clear if you were joining a waitlist, but it’s worth checking the confirmation email you received when entering to be sure. If you’re unsure whether your place is confirmed or you are on the waiting list, feel free to get in touch and we can check for you.
Important: Race Numbers & Number Belts
From this season onward, British Triathlon requires race numbers to be worn at all events. This means all competitors at the Harwich Triathlon will need to display their race number during the race.
To make this easier—particularly in transition—we recommend using a number belt. These simple elastic belts allow you to attach your race number once and then quickly rotate it depending on the discipline (typically on your back during the bike and on your front during the run).
Using a number belt means:
No need to pin numbers onto different pieces of clothing
Quicker and easier transitions
Less chance of damaging your race kit
If you don’t already have one, they’re inexpensive and widely available online. For example, here’s a simple budget option:

Investing in a small item like this can make race morning smoother and help keep your transitions simple and stress-free. 🏊🚴🏃
Olympic Race Sold Out
The Olympic distance race at the Harwich Triathlon has now officially sold out following strong demand from athletes across the region.
This year’s event has proven extremely popular, with entries filling quickly as competitors look forward to racing along the Harwich seafront and surrounding roads. The Olympic distance race will see athletes take on a 1.5km swim, 40km bike and 10km run in what has become one of the highlights of the local triathlon calendar.
Athletes who attempted to enter after the race sold out have been placed on the waiting list via EntryCentral. If any confirmed participants withdraw, places will be offered to athletes on the waiting list in order.
Anyone currently holding a confirmed place but unable to race is encouraged to either transfer their entry to another athlete or withdraw as soon as possible so that the space can be offered to someone waiting.
We would like to thank everyone for their enthusiasm and support. We look forward to welcoming athletes, volunteers and supporters for another fantastic day of racing in Harwich.

Junior Triathlon - Age Category Explanation
To ensure parents of children are clear on how the age categorisation works for the juniors, I've given some detail below on how it's worked-out. The principles of categorising ages in this way are set by British Triathlon.
Age Categories and How Aging Works
Your child’s age for the event is determined by how old they are on the 31st December of the year the race takes place. This means, for example, if your child turns 9 on or before the 31st December 2026, they will automatically be placed in the 9-12 age category, regardless of the fact they maybe 8 on race day. Similarly, if your child turns 13 on or before the 31st December 2026, they will automatically be placed in the 13-15 age category, regardless of their age on the race day.
Why We’re Using EntryCentral for Entries This Year
We’re excited to announce that entries for this year’s Harwich Triathlon will be managed through EntryCentral — a trusted and British Triathlon–approved entry platform.
Why the change?
From 2025, British Triathlon (BTF) requires that all competitors — in both adult and junior races — have a valid Race Pass (previously known as a Day Licence). This is a form of short-term membership that provides essential public liability insurance and ensures every participant is covered under BTF’s national event insurance.
To meet this new requirement, we had two options:
Ask everyone to enter through our own system and then make a second, separate purchase on the BTF website for their Race Pass, or
Use an approved entry platform that’s fully integrated with British Triathlon.
We’ve chosen EntryCentral because it’s one of the official BTF-approved systems — meaning your Race Pass (if needed) can be automatically added to your entry. It’s simpler, quicker, and ensures that all the necessary insurance and affiliation details are handled correctly at the point of entry.
Volunteering
When you toe the start line of a race - whether it’s a local Parkrun, a marathon, or a grueling Ironman — you’re likely focused on your own goals: setting a personal best, conquering the distance, or simply crossing the finish line. But have you ever stopped to consider the incredible effort that goes on behind the scenes to make these events possible? At the heart of every successful race, triathlon, or endurance event lies a dedicated army of volunteers.
Get involved
Organising an event like a triathlon requires a lot of help from a lot of people (often times, in the background). Some of that help is required weeks before and a substantial amount of helps is required on the day of the races. As the popular moniker goes, volunteer marshals are “race makers” - they make the race happen. Without them, these events cannot take place. It’s as simple as that.
So, it’s in that spirit we kindly request anyone who can help out in anyway they can, in the build-up and particularly on the race days of Saturday 7th June and Sunday 8th June, to make themselves known to us.
Thank you!

Safety Tips for Open Water Swimming
Swimming in open water as part of a triathlon can be exhilarating, but it also presents unique challenges compared to swimming in a pool. Understanding sea safety and preparing adequately can make a significant difference to both your performance and your safety. Here are some essential tips and guidance to ensure a safe and successful open-water swim.

A Huge Thank You from the Harwich Triathlon Team!
What a weekend! The Harwich Triathlon 2025 was a roaring success – and that’s down to the incredible people who gave their time, energy, expertise (and sometimes their sanity!) to make it happen.
To everyone who played a part – whether you were marking out the course at 5am, cheering on athletes, baking goodies, or firing up the timing systems – thank you. This event simply wouldn't happen without the dedication of a small army of generous and passionate individuals.

After a fantastic weekend of racing at the Harwich Triathlon, we’ve ended up with a box of items that didn’t make it home with their owners. Whether it was the post-race buzz, the adrenaline of transition, or just the general chaos of a busy weekend, a few shoes, bags, and other bits and bobs have been left behind.
