Do not play catch-up
Stacking missed runs increases injury risk and ruins the sessions that actually matter.

FAQ
Should I make up a missed run?
Rarely. If it was an easy run, move on. If it was a key workout, shift it only if you have enough recovery before the next hard session.
What if I missed a whole week?
Do not jump back in at full volume. Cut the first week back by 20-30% and delay hard workouts until your legs feel normal.
