Finis Tempo Trainer Pro
theendurancestore.com £31.50 This small yellow device attaches to the strap of your goggles and beeps rhythmically to a predefined tempo. It’s a simple concept but it’s incredibly effective. Benefits: During a swim workout you can use your tempo trainer to help you keep pace. It’s like a coach, yelling at you that you’re going too fast or too slow. Simply set it to beep every time you’re supposed to hit a certain distance, such as 50 metres. They can also be used for testing, measuring and developing your stroke rate. You can set your chosen stroke rate and it’ll beep every time your arm should enter the water. Tip: Time yourself for 100 metres several times, using a different stroke rate each time. Which stroke rates felt the best and gave the fastest times? This helps you work out which is the optimal stroke rate for you.
