In recent years, the power meter has become the primary means of measuring performance for cyclists, even at the amateur level. This has meant that benchmarking fitness – FTP, watts per kilo, cycling training zones, etc – is easily accomplished and no longer requires an expensive trip to the science lab.

But is this widespread devotion to power distracting us from the importance of an older form of fitness measurement, the humble heart rate monitor? In this feature, I want to assess the ongoing relevance and usefulness of monitoring beats per minute. What insights into our performance are picked up in our heart rate traces while not registering on the best power meters for cycling?
