Sessions
Date, place, discipline mix, and how often you are climbing.
Grit Engine
Six metrics from your climbing log.
The Grit Engine is the math layer behind Crux Logs. It reads the climbs you enter and turns them into plain, deterministic summaries of effort, fear, consistency, and project work.
Climbs
Grade, attempts, sends, falls, hangs, flash, and fear rating.
Projects
Repeated tries, notes, timeline, and whether the route eventually went.
How to read it
Context, not a score.
None of these metrics says whether a session was good or bad. They show the shape of the work: where you are trying hard, where fear is changing, and how much attention your projects are getting.
Limit climbing
Push Rate
climbs at your max / total non-warmup climbs- Measures
- How often your logged climbs sit at your current ceiling for that discipline.
- Why it exists
- Some sessions are for mileage. Some are for trying hard. Push Rate shows the mix without turning it into a score.
- Example readout
- You sent 5.11d. That is a new max. Three months ago your hardest was 5.11b.
Fall practice
Fall Willingness
intentional falls / route-climbing sessions- Measures
- How often lead or route sessions include recorded intentional falls.
- Why it exists
- Falling is part of learning to commit. The metric reflects whether that practice is present in the log.
- Example readout
- 3 intentional falls today. Last month you averaged 0 per session. Something shifted.
Bravery
Fear
average fear rating on hard climbs- Measures
- Fear ratings from 1 to 5 on climbs near your current max.
- Why it exists
- Lower fear on similar grades can be progress even when the grade does not move.
- Example readout
- You sent 5.11a today with fear rated 2. Six weeks ago on 5.11a, you rated it 4.5.
Easy versus hard
Comfort Zone
climbs well below max / total non-warmup climbs- Measures
- How much of your climbing is below your current ceiling.
- Why it exists
- Easy volume can be intentional. This makes the ratio visible so you can read it in context.
- Example readout
- All easy terrain this session. Sometimes that is exactly what you need.
Investment
Project Persistence
average attempts before send or abandon- Measures
- How much time you keep returning to the same climb.
- Why it exists
- A project is not just a failed send. It is a record of attention, beta, and repeated tries.
- Example readout
- 44 attempts on Rainbow Roof across 7 sessions. That is investment.
Showing up
Session Consistency
recent sessions / your normal session rhythm- Measures
- Your current climbing rhythm compared with your own history.
- Why it exists
- Consistency is not a guilt metric. It is context for every other trend.
- Example readout
- 12 week streak. 2.5 sessions per week. You are building something real.

Log a few sessions. Let the pattern show itself.
Crux Logs only has something to say after you give it real data. Silence is better than hollow advice.
