Real vert
The engine separates flat kilometers from climbing kilometers (GAP). Long runs are planned by time on feet and target D+, not raw distance.
Trail running
Your trail plan, no coach needed.
Vetta reads your Strava activities, understands your CTL and lays out the week: long runs with vert, hill repeats, fartlek on terrain, recovery. No manual planning.
Goal-driven periodization
Set your 50K, ultra or vertical race and the week falls into the right phase (base → specific → taper) automatically.
Race predictions
VDOT from your history tells you what you can run today in 10K, half and full marathon, with altitude correction if you live high.
Actual philosophies
Polarized, pyramidal, Lydiard, Kilian-mountain. You pick or let the engine decide based on your primary sport.
