jev-running is wild I built this smart pacer with Jev to prep the running splits of my next HYROX. > I run > Jev sees pace, HR trend, RPE, gradient > decides: push, hold, ease off, recover cost: ~$0.000046/decision speed: ~582ms/decision It’s not about chasing a number. It’s about knowing what to do next.
