When life interrupts training

An interruption is any stretch where life, illness or travel takes running out of the week you planned. Every training block meets real life at some point. These questions cover how much fitness a gap actually costs, how to rebuild after it, and how much of a fixed plan you need in the first place.

• Is a missed week of running as bad as it feels?

  What one missed week of running costs your aerobic fitness, why it feels worse than it is, when a gap matters, and what to check in your data.

• Can a Training Week Survive a Work Trip?

  Which session to protect during a work trip, what can flex without cost, how to rebuild the week around travel, and what to check once you are home.

• What happens to my race goal after illness?

  What two weeks of illness costs your fitness, why the comeback carries more risk than the layoff, when a race goal needs to move, and what to check.

• Do you need a full marathon training plan?

  What a marathon build needs in its first weeks, why a full plan written on day one is mostly guesswork, and which parts are worth fixing up front.
