All of our events are open-water swims. Open water swimming is very different to swimming in a clear warm swimming pool, but with the right preparation and practise you don't need to worry! You'll need the following kit to get going:
Swimming cap
A swim cap serves several functions: it helps us keep track of you, it helps keep your head warm and it lowers water resistance and saves you vital seconds in the water. You will need to buy one to train in although you will be provided with one at our events to race in.
Goggles
Are an absolute must to enable to see where you're going and will make a notable difference to your swim. Zoggs' award winning Predator goggles are great for open water swimming. Many triathletes race in contact lenses, but it is vital that your goggles don't leak!
Wetsuit
You will need a wetsuit for an open water swim. Whilst any type of wetsuit (long, short, sleeveless, etc) is ok we would recommend swimming in a triathlon wetsuit. They are designed not only to keep you warm, but also for swimming in, whereas general purpose suits (like those for surfing) can actually make it harder!
There are some great wetsuits on sale and hot deals on offer this season. If you're looking to buy one then check out BlueSeventy's new range. Wetsuits provide more buoyancy than swimming without, resulting in faster swim times. Hire suits are available for as little as £40. For hire or sales call triandrun on 020 8500 4841 or email deals@triandrun.com
Open water swim practice
We would recommend that you practice swimming in you wetsuit before you race. There are a number of open water swim sessions available.

Which goggle is right for you?
The trick to getting a good pair of goggles is selecting a model that fits your face and your eyes, and of course makes you look the business in the water! Zoggs has created a three-step system to ensure you find your perfect match for the water.
Step 1 - Seal
To test the fit you should firstly apply the goggle to the face without the strap in place and test the seal the goggle provides. If a split second of suction is provided then you have a strong indication of a good fit (careful of those eye balls though, our goggles are known to have awesome suction!)
Myth: Tightening the strap will ensure your goggles give a good fit.
Fact: The goggle straps sole purpose is to hold the goggle in position, not to provide the seal. Adjustment of the strap may be necessary, however avoid the temptation to pull the strap too tight, this will simply create uncomfortable pressure on the delicate eye area, not to mention unsightly panda eye effect!
Step 2 - Fit
Once you have found a good seal you should fit the headstrap by careful adjustment and then focus on two area:
• Comfort around the nosebridge, the goggle should sit comfortably around the nose and create a good seal.
• Seal around the eye should sit comfortably and not wrap too far around the corner of the eye. This can be tricky to gauge so ask our ‘Goggle doctors’ to assist you with this and use the mirrors provided to check for gaps.
Step 3 – Style
We always recommend trying 2-3 different models, this will help you compare fit, comfort and validate your purchase decision.
Our goggle range is extensive, with over 30 models, to suit differing face shapes, ages and desires you’ll be spoilt for choice.

Don't overlook technique work, especially early in the season. Try incorporating some stroke work into every work out that you do during January and February and get into a habit of counting the number of strokes it takes to complete a length.

Technique Tips
Don't overlook technique work, especially early in the season. Try incorporating some stroke work into every work out that you do during January and February and get into a habit of counting the number of strokes it takes to complete a length. Aim to reduce your stroke count but maintain a similar speed.
Good technique will help you to swim faster whilst conserving energy. Try to remember the following:
• Your head position should be looking down and slightly forward
• Your hand should enter the water tilted so that it is thumb-down
• Roll your body down to the side of the entering hand, using your shoulder to push forward
• Rotate your hand around the thumb position, moving the hand into a thumb-inwards orientation - you should start to `catch´ the water at this point
• Keep your elbow high as if pulling `over a barrel´ - perform this part of the stroke slowly
• Bend your elbow to pull your hand under the centre line of your body
• Push your hand past your hips, applying force to get the maximum length out of your stroke
• As your arm recovers over the water keep your hand relaxed and your elbow high
• Use your natural body roll to bring your face into a position to breathe rather than moving your head independently of your body
• Use a shallow kicking technique
Long strokes
How many strokes does it take you to swim a length of front crawl? And, why is this even important?
Your stroke rate is the number of arm rotations it takes you to get from one end of the pool to the other. Every swimmer will have an optimum number - the lowest number that achieves the best average speed. Top swimmers will be able to swim a length of a 25m pool at top speed in around 12 strokes. If you aim for low 20s, that´s great.
Swimming a length with a high number of strokes might be slightly faster, but you will get tired more quickly and your stroke will be less efficient.
Have you ever heard of pool golf? This is where swimmers count their number of strokes per length and aim to reduce their scores. Apparently, Welsh Olympic medallist David Davies can do a length of a 50m pool in 9 strokes!
Pool golf is a good drill to do in the pool every so often. Try swimming 8 x 1 length, swimming your normal stroke for the first length. Count your strokes as you swim. Then try to reduce the number of strokes on every subsequent length. By the 8th length your stroke will be really slow and deliberate, but you might find that you have hit your optimum stroke length on the 3rd or 4th length.
Focus on the following to lengthen your stroke:
• Stretch forward at the start stroke and pause briefly before starting your under water pull
• Pull your hand under the centre line of your body
• Pull your hand all the way past your hips
• Recover your arm over the water with your elbow high
Technique Drills
Try these simple drills to improve your technique:
High elbow
Over emphasise the high elbow position as your hand passes your shoulder and head during the recovery phase of the stroke. This drill should stop you swimming with your arms too wide or flailing like a windmill. If you find it difficult you should consider some shoulder flexibility work.
Distance per stroke
Try to get the maximum distance from every arm pull. This means really stretching out at the front of your stroke and pulling all the way past your hips.
One-arm catch
Swim with your left arm stretched out in front of your body whilst your right arm slowly performs the arm stroke. Concentrate on kicking at a high kick rate and breath to the arm that is performing the arm stroke. Do this for one length. Repeat the drill on the other side. This drill will help establish stroke balance.
Tumble Turns
So you´ve just about mastered the front crawl, but have you got your head around the tumble turn yet? Our tumble turn tips will hopefully have you head over heels!
Using a tumble turn will enable you to turn faster and maintain momentum without disrupting the rhythm and stroke. A tumble turn is basically a somersault with a twist. Try following the steps below:
Swim towards the wall
When you see the T on the bottom of the pool use your arm to pull you through a somersault just in front of the wall Place your feet on the wall and stretch your arms forward (in the direction that you want to go) push off the wall and twist onto your front. Don´t forget to kick your legs.
You can break this down by first practicing a somersault in the water, then try doing a few strokes and somersaulting before you get to the wall.
Next, try this next to the wall and get your feet to connect with the wall. Make sure that you don´t approach the wall too slowly - you´ll need some momentum to enable you to perform the turn.
Once you can get your feet to connect with the wall, you can practice getting your body into the right position to perform a streamlined push off.
Beating Cramp
Do you often get cramp when you´re swimming? No one really knows what causes cramps, but there are several factors associated with them:
• Over exertion (i.e. longer duration or higher intensity than normal)
• Inadequate warm up or stretching before exercise
• Extreme heat and cold temperatures
• Dehydration
• Salt imbalances after sweating
• Low blood sugar
Gentle stretching can help relieve all types of cramp. You can also try applying ice (wrapped in a towel rather than directly onto the skin) as this will numb the area and increase blood flow when the ice is removed. Gentle massage and replacing lost fluids may also help. Never forget your water bottle: drink after your warm up, in rests if doing intervals and between sets.
Try these tips to prevent cramp:
• Increase the intensity and length of your work outs gradually
• Take your water bottle to the pool and ensure that you stay well hydrated
• Maintain your glycogen stores (your body´s store of energy)
• Replace lost energy after your work out by eating complex carbohydrates such as pasta and bananas
• Stretch before and after exercise to help prevent the muscle´s susceptibility to cramp
Race Day
Competition Tips
• Avoid blurred vision by swimming in a pair of goggles with anti-fog technology. Zoggs goggles feature FogbusterTM Anti-fog, why not try the Vortex mask or Sonic Vision goggles for UV-protection too?
• Avoid other swimmers grabbing your ankles by putting Vaseline on them before the race starts.
• If you're worried about your goggles coming off - try a mask like the Zoggs Predator. Tighten the straps and consider putting your swim cap over your goggle straps Wear your tri suit under your wet suit to save time and hassle in transition.
• If you get cold, wear a silicone cap under the race cap that the organiser supplies. Try the Zoggs moulded silicone cap.
• Swim out and back a couple of times in open water to get used to the temperature and visibility. Take this opportunity to prepare yourself by sighting the first buoy.
• Start in the race in the right place for your speed and experience. Too far forward, and faster swimmers will swim over you. Too far back and you´ll be held up by others.
• Swim in a straight line and don´t follow other people - they may be going off course. Know the route beforehand and sight often as you swim.
• Pace yourself - don't go off too fast. Ease in to the race and pass everyone later.
Open Water Swimming
If you are competing in an open water triathlon event you will need to adjust your technique slightly, and make sure you have a decent pair of fog busting, UV-protection goggles! You should aim to lift your head and look forward approximately every 8-10 strokes. This is called `sighting´ and enables you to keep swimming in the straightest - and shortest - line to the finish or marker buoys. For example, if you usually breathe every four strokes you can alternate a breath to the left or right with one looking straight ahead. Going off course is one of the key things that slows triathletes down, so keep your eye on the buoys and markers and head directly to them.
Don´t just follow everyone else as they might be going off course. You need to be able to guide yourself if you find yourself leading a pack.
Practice starting off from treading water. This is called a `deep water start´ and will be an invaluable skill when starting an open water race from the water. The key is to tread water gently whilst waiting for the starter, in order to keep your heartrate low and calm. As the time is counted down, lay out flat to claim your bit of water space. Once the race has started, start to pull with your arms for a few strokes to get you clear of other swimmers. Then you can start to kick without anyone being on top of you.
`Mass starts´ - where you start in a pack with all the other swimmers - can be daunting but are really nothing to worry about. If you think you need more space, position yourself at the back or side of the pack where things will be quieter, but realise that this will place you behind everyone - not ideal if you are a faster swimmer. Take your time, tread water if you need to, and don´t panic. Everyone else is in the same situation as you, and everyone just wants to get swimming. If you do get knocked or dunked, take a moment to reposition yourself and calm your breathing, and then carry on.

blueseventy wetsuits introduce the Helix, simply the finest suit ever.
“I have never swum as well as in a Helix”
- Bryan Rhodes (Ironman Champion)
The culmination of years of testing and research, the helix is simply our finest suit ever. For 2008 we introduce TST, torsional stretch technology, further isolating the shoulder panels from the body of the suit, to improve flexibility. Combined with the existing quick exit legs, reverse zipper and multi-stretch cuffs, the helix improvements result in uncompromising comfort and performance. In 2007 this was the suit of choice for athletes in the pro ranks, and based on their feedback, has led to enhancements that will not change that perception.
