Type in a time.
Get the splits
to chase for weeks.

Every split tells a story. Turn your last piece into a clear path forward — one workout at a time, one second closer to the time you're chasing.

Training conditions

What's it like out there?

Check current weather and the next 9 hours before you head out. Heat, cold, and wind all shift your target splits.

Technique library

Nail the fundamentals

Better form turns the same effort into free speed — and helps keep you injury-free.

Sports & mental health

The other half of training

The best athletes take care of their minds and treat their competitors with respect.

How Time Crunch thinks
01
Riegel-based projection
Your recent piece is converted to a threshold pace using Peter Riegel's endurance formula, then scaled to the split unit for your sport.
02
Zone-anchored sessions
Every workout has a target expressed as a % of your threshold pace — steady state, threshold, VO2 max, and sprint.
03
Progressive overload
Weekly targets tighten on an ease-out curve so gains come from base early and sharpen late, ending in a taper.
