I just finished up a new app for calculating the effects of heat and humidity on workout and race paces—a “heat-adjusted pace.”
☀️ Check out my new heat-adjusted pace calculator here! 🌡️
This app builds on the work I wrote about in a post earlier this year on heat and humidity’s effects on marathon performance.
This web app uses a statistical model fit to nearly 4,000 marathon performances to estimate the effects of both heat and humidity on race and workout times. You can enter weather conditions as a heat index, temperature and relative humidity, or temperature and dew point.
Although the app is built on data from marathon races, it’s also useful for long tempo runs, easy runs, and other long sessions in the heat.
