For runners
The AI running app that takes you from couch to 5K through a marathon training plan.
Coach Elias plans your blocks, watches your heart rate zone distribution, tracks cardiac drift, and pushes back when your Tuesday tempo runs at Wednesday easy pace. From couch to 5K through Boston qualifier, and every distance in between.

What's inside
What runners actually need
Block-based coaching
Build, stress, recover, sharpen. Elias talks through training in 4-8 week blocks with explicit purposes so every week has a job.
Heart rate zone discipline
Pace and average HR per run are captured automatically. Elias coaches the polarized 80/20 split from that data, keeping your Z2 easy days truly easy and your hard days hard.
Pace + HR feedback
Pace-vs-HR is the cleanest aerobic-base signal we capture today. Elias reads it run-by-run and flags cardiac drift when your easy pace costs more heartbeats than it should.
Race time predictions
A Race Predictor card models your goal-distance time (1mi through 50K) from your recent run history and flags confidence.
Recovery-aware sessions
Low HRV days bump easy runs; truly bad days hold key sessions. Same data layer as Max and Lauryn.
Race-week taper
Elias walks you through taper week based on the block you ran: volume drops, sharpening intervals stay, race-day pacing prep. The conversation does the work.

The honest playbook
80% of distance runs should be boringly easy in Z2. 20% should be hard. Most app-tracked runners get this wrong, running everything at one moderate pace and wondering why they’re not improving. The running tracker reads your weekly pace and heart rate pattern, and Elias calls drift in either direction in chat.
For race prep, weekly volume ramps matter more than any single workout. ACWR (acute-to-chronic workload ratio) is something Elias watches when reading your mileage history. Most overuse injuries come from going 30mi to 45mi in 3 weeks, and Elias will flag it before you get there.
Pace at the same average HR trending faster over weeks = your aerobic base is improving. The opposite = something is fatigued or under-recovered. Elias reads it both ways from your run log and adjusts what he recommends next.
