Marathon Time Conversion

This tool compares marathons and converts times using data for what you would expect on a typical race day. For example, use this tool to see how much faster or slower you would expect to run if the weather was normal for race day and run on the current year's course.

If you want to compare specific race years and courses or to see how the current weather forecast may affect marathons scheduled this week, use the Year by Year Time Converter.
