Serious road cyclists tend to like using cycling computers (or "cyclometers") to provide them with performance data such as their speed, cadence, distance traveled and power output. Swimmers can also get their pruned-up hands on tech that makes keeping tabs on training sessions much easier and this example from Speedo will appeal to pool-goers for one reason in particular - it automatically counts laps. The Speedo Aquacoach watch uses technology developed by UK-based Swimovate to automatically detect the stroke and - along with counting laps - calculate distance, speed, number of strokes and calories burned.
For swimmers and triathletes in training or racing, keeping a tab on laps is tedious, but also it can be easy to lose track at times, especially as you tire. Plus there are frankly better things to think about while you’re working out in the pool. British company Swimovate has come up with a swimming computer, worn like a wristwatch, which takes the mental work out of keeping a lap count. But being a smart bit of tech, the Pool-Mate does a heap more besides.
