Frequently asked questions

How are gradients different from Strava segments?
Strava segments are about competition: who is fastest on a known stretch, leaderboards. Our gradients are about training: you specify which climb or descent to work on, its slope and length, and the map finds matching sections nearby. Or it highlights the terrain missing from your training that you'll face on race day.
Do I need a specific watch or Strava Premium?
No. A free Strava account is enough – it's the only source for your activities. There are no other integrations at the moment. (Garmin, Coros, Suunto, Apple Watch are planned).
What Strava data do you use and can I revoke access?
The activities you authorize build your experience matrix for gradients. You can revoke access anytime in Strava: Settings → "My Apps" (strava.com/settings/apps) → next to Endurance Analytics click "Revoke Access" – we will immediately stop pulling new activities. Or email us at contact@endurance-analytics.com.
My race isn't in the catalog – what should I do?
Upload the course's GPX track. The track will undergo the same processing: DEM elevation, gradient breakdown, difficulty rating, and finish time estimate. You can also add checkpoints and distribute nutrition and hydration automatically or manually.
How do I find a missing descent?
Race Fit shows which slopes and lengths are missing from your experience (gray gradients). The Gradient Search Map finds real sections of the required steepness near you or anywhere in the trail running world.
What does "14 days free" mean?
This is a trial period for the paid subscription: when signing up for Bro, a card is linked, but the first 14 days are €0. The first charge occurs on day 15. You can cancel anytime in the Creem portal – if you cancel before the trial ends, nothing will be charged. The free account works without this, no card needed.
