Work out the race
before you run it.
Six calculators for pace, heart-rate zones, fueling and finish times. No account, no email. When you want the same numbers read from the run you actually did, the Crenoe app does that.
Also from Crenoe
The calculators read what you type. The app reads the run you did.
Bring your runs from Strava, Health Connect, or your watch files, and Crenoe pulls 16+ metrics from each one: grade-adjusted pace, aerobic decoupling, cadence variability, ACWR, and fitness and fatigue (CTL/ATL/TSB). It builds a plan from your VDOT, and turns any run into one of 90 sticker templates.
