HardloopCalculator provides a set of calculators and tools focused on running metrics. The platform offers various plugins and extensions designed for personal use, supporting runners and those interested in running-related calculations.

Among its available options, HardloopCalculator features a WordPress plugin that allows users to publish the calculator on their own website. There is also a Chrome browser extension, enabling access to the calculator across the web. Additionally, the service mentions the possibility of creating a custom tool or exclusive plugin for individual use, with contact details provided for such requests.

The calculators cover a range of running-related topics, including conversions between speed and pace (such as km/h to min/km and min/km to km/h), marathon and half marathon pacing, negative splits, and calculations for running time and distance. Other tools address training metrics like VO2max, anaerobic threshold, heart rate zones, calorie consumption, and recovery time. There are also features for predicting race results and for converting between different units relevant to runners, such as kilometers to miles or steps to kilometers.

The WordPress plugin and Chrome extension are both available for free download. The site and its tools are credited as being powered by Robbert Tigchelaar. HardloopCalculator is positioned as a resource for individuals looking to calculate and optimize various aspects of their running performance.
