Frequently asked questions
How long is the Marathon training plan?+
The plan runs about 16 weeks, but RUNNIQ adjusts the length to your goal date and current fitness when you sign up.
How many days a week will I run?+
This plan is built around 4 running days a week. You can tell RUNNIQ how many days you have and it rebuilds the week to fit.
What if I get sick or miss a week?+
That's the core of RUNNIQ. When you miss sessions, fall ill, or travel, the plan automatically reshapes the remaining weeks so you arrive at your race fit, not overcooked.
Do I need a watch or Strava?+
It helps but isn't required. Connect Strava and RUNNIQ analyses your runs to set personalised zones; without it you can still follow effort-based guidance.
Is the sample week below the whole plan?+
No — it's a preview of week one. The full periodised plan, personalised to your zones and life, is generated when you start.

“I got the flu three weeks out and panicked. RUNNIQ just rebuilt the plan around it — I still PR'd by four minutes.”
Marina S. · First half marathon
“I hadn't run since school. The walk-run weeks were exactly my level and it never made me feel behind.”
Diego M. · Couch to 5K
“The daily feedback after each run is what kept me honest. It felt like a coach who actually saw my training.”
Aisha K. · Marathon, Berlin
“Travelled for work twice during the block. Each time the plan shifted my long runs without me asking. Knocked 90 seconds off.”
