I don't know anything about running; I haven't gone on a run in 5+ years. However, when inspecting the Calculate button from Runner's World, the site runs a function called runConversion(). A quick Ctrl+F for that in the source gives us script: <script language="JavaScript"> <!-- var metric; var VO2max; function ...

When starting out, we so commonly jump straight into running. This is natural, perhaps, since we all remember running around so effortlessly when we were young children. But it is so easy to forget that we also skipped, jumped, climbed trees, and suspended and swung ourselves on the monkey bars, too. Few of us can do these things without risk as we get older,...

RunDisney events suffer from balloon lady fear. Nobody wants to get dropped off of the back to get swept up by the "Bus Of Fail". So people cheat in many different ways.

Long overdue Here is a 12-week plan with more info on this link yet I would not recommend you to neither follow the plan nor do any ultras based on the very limited information that you've provided in your question: Ultras are for those who can at least finish a road marathon below 3:00/3:30 hours and they have an athletic/excellent Rest Heart Rate. You ...

There's a lot of confounding variables in your data. The first one I noticed is relevant to world leaders. Survivorship bias You don't typically get to run a country until you're in your 40s at least. The US seems set on mid to late 70s at the moment... Runners typically peak before 30 (marathoners just before 30). So a runner has to make it 70 more ...
