This week on The Long Run: Mum and Dad are fighting — Strava is suing Garmin. What’s actually going on, and would Strava survive without Garmin uploads? Then we dive into the Boston Marathon’s new downhill indexing rule, where net-downhill courses will now face time penalties of up to ten minutes for qualification. We go Around the Track with the Saddles 50 & 100 Miler in Arizona, break down the Melbourne Marathon course, and look at P.volve’s new Sculpt 9 amino supplement — a formula claiming to keep women’s muscle response consistent across the entire cycle. Plus, as always, our week of training.
