From the organizer

Organizer's website

On behalf of the President and Members of Tonbridge Lions Club I would like to welcome you to the Tonbridge Triathlon. We have held the triathlon for 25 years and have raised over 200,000. This year we hope to raise over 13,000. All the proceeds go to local charities and causes who are grateful for your support.

Our aim is, as always, to provide an event that is enjoyed by the competitors and spectators alike while raising money for local charities. On behalf of this year's charities, we would like to thank you for your support and hope that you and your supporters have a great day.

Course Details


This is in the indoor heated swimming pool, water temperature is above 22C, therefore, wet suits are forbidden. It is illegal to use calf and arm compression items or any other device that aids propulsion. Please report at the swim start at least 5 minutes before your estimated start time. Your race start time is detailed in these instructions and on the website.

Spectators are allowed to watch from the sidelines in the swimming pool.

You will be swimming 3 to a lane and will be called forward in race number order or as spaces become available. If you find someone in the lane is faster than you please let them pass at the lane end (you can catch them on the bike route).

Should there be space in the pool and you wish to start earlier than your allotted time, please ask the Race Director in charge of the pool and he will do his best to accommodate you.

If you are either a particularly fast or slow swimmer please advise the starters who will do their best to place you with others of similar ability.

You will be given a coloured swim hat to wear, this helps the lap counters. You will be shown a board when you have 2 laps remaining.

The BTF Race Referee will be the final arbiter in the event of a dispute concerning the number of lengths completed. Any queries should be raised after the completion of the run discipline. Such complaint to be in writing and to be submitted no later than 20 minutes after completion.

When exiting the pool you must remove the swim cap and leave it in the pool area before making you way to the exit. Transition is some way from the pool and you may wish to have suitable footwear available OUTSIDE the pool exit. No outside footwear is permitted in the pool area.


To further ensure your safety on the cycle route we have been fortunate to obtain a road closure notice on Carters Hill, Underriver, to traffic travelling in the opposing direction to the race.

You must still ride in a safe and considerate manner and be able to stop in the distance you see to be clear. Despite the road closure order traffic may still get onto the road and travel in the direction opposing the race.

During the cycle discipline you must obey the normal rules of the road and the Highway Code. Any failure to follow the instruction given by a race official, marshal or Police Officer, riding dangerously is unacceptable and will not be condoned. Exhibiting behaviour likely to bring the sport into disrepute etc. could result in injury and jeopardise future events.

Your cycle helmet must be worn and fully fastened before your bike is un-racked and must remain so until it is re-racked at the conclusion of the cycle discipline.No HELMET – No RACE! It is your responsibility to ensure that your bike is in a roadworthy condition.

Be aware that the roads are open to the public and care should be exercised when completing the cycle discipline. The roads may have potholes due to the winter weather etc.

On the downhill section at Carter's Hill, marshals have been issued with yellow warning flags. Please note: if a yellow flag is being waved, you MUST SLOW DOWN.


The course will be the same as last year with the entire run route being within Tonbridge School grounds. It is a flat course on a grass surface for the main part.

Standard competitors will run down to the playing field from Transition and complete FOUR laps of the field, then complete one lap of the running track, finishing on the outside in front of the sports centre.

Sprint competitors will run down to the playing field from Transition and complete TWO laps of the field, then complete one lap of the running track, finishing on the outside in front of the sports centre.

Go-Tri competitors will run down to the playing field from Transition and complete ONE lap of the small field, then return to the running track and complete one lap, finishing on the outside in front of the sports centre.

Raceday Logistics

Please ensure that you arrive in plenty of time to register and rack your bike in transition, it will be busy.

Race day registration will be in the main sports centre outside the coffee shop, and will be open from 0600 hours. At registration you will collect your race number, bike identity stickers, and safety pins. You may use a race number belt if you wish.


Spectators are allowed to watch from the sidelines in the swimming pool.


I have a temperature, am I still fit to compete?

A lot can and does happen between placing your race entry and the event itself. Entrants who are fund-raising for charity often feel under pressure to take part even if they feel unwell or unfit because of the money they hope to raise. You should never compete with a fever, as there is a risk of causing myocarditis (inflammation of the heart), which can be fatal or debilitating in the long term.

Do not compete if you feel unwell or have just been unwell. Most medical emergencies occur in people who have been unwell or have been unwell but do not wish to miss the race. If you feel feverish, have been vomiting, have had severe diarrhoea or any chest pains, or otherwise feel unwell, it is unfair or you your family and the event support staff to risk becoming a medical emergency. You are unlikely to perform well and do yourself justice. There are other races but only one you.If you are not fit then please withdraw from the event for your own safety.

What if I normally take medication?

Many entrants do have a history of medical problems or will be taking medications or use inhalers. This information is invaluable to the medical support staff in the unlikely event of an emergency or if you collapse. For example, knowing that you are a diabetic or asthmatic can speed the diagnosis and treatment of your problem.

Please enter your medical details on the reverse of your race number. If you do not, it may prolong the time taken to give you the appropriate treatment.

Are there changing facilities available?

There are facilities at the Swimming Centre. Tonbridge Lions Club does not accept responsibility for any property lost or stolen, so please look after your own property.
