A common challenge when doing track workouts or races is non-ideal wind conditions. This calculator applies the same validated scientific model from my wind-adjusted pace calculator to the specific geometry of the track.
Scientifically speaking, this is probably the most advanced calculator I’ve ever made, and yet it’s still super easy to use. All you need to know is your pace (or calm-day effort level), the wind speed, and the wind direction. Everything else is taken care of by the web app!
This app uses state-of-the-art biomechanics and physiology data, alongside a rigorous mathematical treatment of track geometry, to accurately account for the turns on an outdoor track.
My new app even supports “non-integer lap” distances for workouts like 200m, 600m, or 1k repeats (a favorite trick of mine for dealing with windy days at the track).

If you want to know when my next training-related app comes out, sign up for my free email list below! You'll be the first to find out when I have new articles or new web apps, and you might even get early access to my newest projects.
Even if you've got your training figured out for the spring, you should check out my new book, Marathon Excellence for Everyone, for state-of-the-art strategies for fueling, pacing, heat adaptation, and post-season training reviews.
I’m excited to launch a new app for predicting training paces: my LT1 and Zone 2 pace calculator is now live, and provides a simple and accurate way to estimate your first lactate threshold, or LT1 pace, as well as an upper limit for your easy run pace, a.k.a. Zone 2 pace. 📲 Check out ... Read more
I recently published a critical speed calculator app, which makes it super easy to use the critical speed model to estimate your steady-state max. However, the critical speed model is not the most accurate way to predict race performance at new distances—that honor belongs to power law models (sometimes also called Riegel models, after Pete ...

When I published my detailed write-up on the science of critical speed for runners, I promised that I would code up a free calculator to calculate your critical speed (also known as “critical velocity” or CV) from a set of race performances. That calculator is now finished! ⏱️ Try my critical speed calculator here! ⏱️ ... Read more
I just updated my pace percentage calculator with a couple of handy new features. The web app now supports decimal input and output, 200m splits, and between-session pace memory. 📱 Try out the updated pace percentage calculator here! 📱 These are small changes but make life a lot easier if you are planning Canova-style percentage-based ...

I just released a brand new web app for track workouts and races on windy days! A common challenge when doing track workouts or races is non-ideal wind conditions. This calculator applies the same validated scientific model from my wind-adjusted pace calculator to the specific geometry of the track. Scientifically speaking, this is probably the ... Read more
If you’ve been looking for an easy way to sync your marathon workouts to your phone, I have some good news. The Marathon Excellence training plans are now supported by the awesome and free Defy Calendar Hack tool developed by “Nanreh,” a runner and cyclist in San Francisco! If you've wanted to sync your marathon ... Read more
I just launched a new web app: a simple and fast race-pace calculator! 🏃♀️ Try out my new race pace calculator here! 🏃♂️ After crunching pace-to-race and race-to-pace calculations by hand for about the millionth time, I decided I needed a fast and easy way to quickly play around with different paces and target race ...
