Kit List

There are several things that you will need on the day to help you to perform your best. The following is a list of our suggestions:

• Warm/suitable clothes for prior to and after the event
• Safety pins for race number
• Race numbers attached to your race t-shirt or race belt, with any medical conditions clearly written on the back of both numbers. You will need to show your race numbers to get into transition
• Triathlon suit – all-in-one, two piece or equivalent; or swim costume, t-shirt and shorts
• Goggles
• Bike – leave it set up in transition in a low gear so you can get going easily!
• Spare inner tube and tyre levers (in case you get a flat tyre en route) – probably best to store these in an under-saddlebag, crossbar bag, or similar
• Tyre pump – probably mounted on your bike
• Helmet (with the straps undone and untangled, ready to quickly put on). Your helmet must be put on BEFORE you TOUCH your bike in transition
• Talc – leave ready-sprinkled in your cycle shoes (your feet may be wet after your swim)
• Towel – to dry your face/hands after your swim
• Bike shoes (if using a separate pair of clip-in shoes)
• Drink bottle with your preferred drink in, stored on your bike
• Energy bars/gels – taped to your bike, or stuffed in a pocket
• Running shoes (some people prefer elasticated laces to aid the speed at which these can be put on)
• Socks – if you prefer these with your bike and/or running shoes
• Another good tip is to memorise your bike position in transition, and walk through each stage of coming in and out of transition before you start your event

For our pool-based events we ask that you do NOT wear a wetsuit – the water temperature is too warm for this piece of equipment.


Spectators are always welcome! Our venues have plenty to keep you entertained, with great viewing points from which to watch the competitors.

The Radley Triathlon is looking for volunteers to act as marshals at the event. Whether you would be looking to increase your voluntary hours or amount of time working in events, or simply enjoy getting involved and helping out, then you are the right person for us!

Our volunteers are vital for the success of our events so we really appreciate the help that you provide and we try to ensure that the day is fun for all involved! Please sign up at:

Can anyone be a triathlete?

Yes, absolutely anyone can be a triathlete. Anyone who can swim, bike and run can participate in a triathlon, which also means that physically challenged people can race. The most famous team in the triathlon world is Team Hoyt, comprised of a father who races with his physically challenged son in marathons, duathlons and Ironman's (triathlons) all over the world. Check out Team Hoyt for more information or for a lifetime's worth of inspiration!

Can I use any stroke during the swim?

You can use any forward stroke except backstroke. This can easily be confused with the distress signal, therefore backstroke is not allowed. We recommend that you swim front crawl or breaststroke.

Can I use a mountain bike?

You can use any bike as long as it is in good working condition. Your brakes and general condition of your bike will be checked before you enter transition. If you are concerned about the working condition of your bike, then we advise you to have a professional check before the event.

Does my helmet meet safety standards?

Your helmet will pass the safety inspection as long as it has no cracks in it, no damage and bears a CE & EU safety mark inside it. The strap must also be in good working order.

Is there water available on the bike course?

There will only be water at the finish. It is your responsibility to ensure that you have enough fluid to keep yourself hydrated on the cycle.

Can I use Tri Bars?

You can use Tri Bars as long as they are secure and have no sharp edges.

What is drafting?

Getting too close to the rider in front and saving energy from the wind shield. Try to maintain a 7x3m box around the back of the rider in front. As a general rule, either pass the person in front or stay well behind.
