You may have seen other swimmers using pull buoys in the pool, but what are they and how can they help your triathlon training?

What is a pull buoy?

Put simply, a pull buoy is a figure-of-eight shaped piece of buoyant foam that you place between your thighs to give you lift in the water. This is useful for triathletes as it helps simulate the body position you achieve from using a wetsuit in the open water, lifting your legs and helping you achieve a more streamlined body position, staying more horizontal in the water.

As well as replicating your ‘wetsuit position’, a pull buoy also allows you to forget about your legs and kick for a while in training, meaning you can focus more on elements such as the front of your stroke, or your rotation. Many swim drills will also recommend using a pull buoy, so it’s useful to have one in your kit bag before heading to a coached group session.

Types of pull buoy

Pull buoys are pretty simple in design, but there are a few variations in the market to look out for. Think about how much lift you want – those with denser, sinkier legs (usually the men!) may want a slightly larger pull buoy with more buoyancy, such as Huub’s ‘Big Buoy’, while those who have a more horizontal position and just want to focus on front-end stroke for a while may choose a smaller, less buoyant one.

Choosing more buoyancy than you need may pinch your lower back, so it’s worth reading on to see the range in the market before buying.

Pull buoys for swimrun

The other reason you may be considering a pull buoy is for a swimrun race, where a pull buoy is allowed to ‘save’ your legs for the run. Again, consider the amount of buoyancy you need, allowing for any extra you will also get from any buoyancy in your wetsuit or calf guards.

You will also need to attach straps/elastic to your pull buoy to keep it in place – most swimrunners attach it to one leg then pull it round to sit on the outer thigh while running.
