The first step is to make sure that you pull enough loose material up the arms and legs. Use a plastic bag over your hand or foot as you slide them into the suit, this helps the suit slip on. At the ankles and wrist pull your suit up 5cm (2 inches) more than you might normally do:
Work this material up your legs to the groin area and up your arms to the shoulders:
Now have your friend slide their hand inside the suit down towards your tricep and with their other hand work the material up the arm and round from the chest on both sides. This is the "human shoehorn" :
Take care not to over-stress the suit doing this as you might tear it. You're just trying to position the suit nicely on your body, not stretch it. The last thing you want to do is rip your suit immediately before a race!
Without using this method you will have a wide gap across your back between the zip and when you do up your suit it will compresses your shoulders and makes things very tight. After Human Shoehorning your suit will sit quite differently with the zip almost together on your back, which can be easily done up:
Now your shoulders will be much more free and loose, ready for a great swim split!
One last tip, as you get in the water pull the neck open a touch and let some water in. This helps lubricate the suit and the water acts as an additional layer of insulation once warmed up.
Have a great race and let us know how you go on the blog comments here.
