📈 The 10% Rule: Is It a Valid Way to Increase Your Weekly Running Mileage?

Strava Deletes Over 4 Million “Cheating” Activities

🚨📱 Strava just erased over 4 million fake activities—quietly.
A new machine learning model is cleaning up the leaderboards, flagging mislabeled runs, suspicious sprints, and flat-out fakes.

It’s one of Strava’s boldest moves yet—and a serious shift back toward real effort and honest competition. 🔍🏃‍♂️

🎧 Tempo Run Needs a Redefinition — And We Finally Gave It One

Is “tempo run” the most misused term in running? 🤔🏃‍♀️

In our latest episode of the Marathon Handbook Podcast 🎙️, Michael Doyle, Katelyn Tocci, and Alex Cyr dig into why “tempo” has become a throwaway label in training plans—and why it might be time to retire the term altogether. 🗑️

They unpack what tempo is supposed to mean 📏, how it differs from lactate threshold, marathon pace, and steady state running 🧠, and share some hilariously awful “tempo” workouts in the debut of their Tempo Run Hall of Shame 😂.
