Pacing lab
Pacing is applied physiology: the best plan fails if you spend your budget early.
Start here
- • Pick a conservative default, then earn aggression late.
- • Use splits as guardrails, not handcuffs: adjust to heat, wind, and terrain.
- • Practice race-pace when tired; that’s where pacing actually breaks.
