FORM smart swim goggles allow you to see your swim activity, stats and training plan inside the lens of the goggle, as you swim! There is structured workout support for these head-up display swim goggles, as well as Open water support when paired with a Garmin watch or Apple watch.

This allows you to pick your workout from a library of workouts, and then the goggles will take you through each step, noting the specified intensity and stroke information – all in real-time.

This feature is available for all FORM swim goggles. But it’s not free. You need to pay for a monthly or annual subscription. However, the company offers a free 30-day trial to test things out, and there is a 12 month warranty.

FINIS tempo trainer

The FINIS tempo trainer is a small yellow plastic disc-shaped device that attaches to your swim goggles strap. It used to improve your swim stroke timing and effectiveness.

Essentially, it works by emitting an audible beep at a pre-set time interval. It's a simple concept but requires a little time and attention to set it up correctly, to get the maximum benefit.

The first step is to swim a couple of lengths of the pool to warm up and get into 'your stroke'. Then swim one more length at a quick pace (not flat-out), concentrating on good style, and counting the number of strokes it takes you to complete the length.

Once you have this stroke count for one length, your next aim is to reduce the number of strokes required by one. You do this by concentrating on your catch and pull, trying to increase the power of each stroke. You set the tempo trainer to emit a beep for each stroke you want to take to reach your target. 

Once you are able to achieve your new reduced stroke count for one length, you repeat the process, trying to do a length in another stroke less. It may take a few days or a few weeks to achieve, but it is a very effective way of helping you to swim more efficiently and powerfully.

Polar H10 Heart Rate sensor

The Polar H10 is a heart rate sensor that works as an ECG (electrocardiogram) device, as opposed to an optical hear rate sensor used in sports watches. This means that it is more accurate.

It is on a chest strap, and is aimed at road cyclists, long-distance runners, and triathletes. Of course, it can also be used by swimrunners during training.

The H10 has a battery capacity of 400 hours, so does not need frequent recharging. It's also waterproof to 30 meters, so can be worn during swim training. Users have reported it to be tough, reliable, accurate and comfortable to wear. It weighs a mere 60g, including the strap.

On the downside, it has limited internal memory, and can only hold one training session at a time. This means you will need to sync your session data with the app (Polar Beat) before doing a new session.But you don't have to use the Polar Beat app. The H10 is also compatible with a host of popular third-party fitness apps, including Cardio Mapper, Endomondo, iSmooth Run and Runtastic.

The Triton Wear system is essentially swim training data recording system. It is a small device that you wear under your swimcap, at the back, just above the nape of your neck.The exact positioning is important.

What does it do? 

It records a multitude of data, including pace, strokes, breaths, distance per stroke, stroke rate, SWOLF, as well as a host of other parameters.

The idea is to give you as much information as possible to improve your swimming efficiency and speed. Definitely worth looking at if you want to improve your swimming performance!

Low-Tech swim resistance

A cheap and simple way to increase swim resistance when training in open water is to clip a plastic shopping bag to the other end of your swim tether. As you swim, the bag fills with water and acts like a drogue or sea anchor. This creates drag, and you have to put in much more effort!
