Frequently asked questions
Does the app cost anything?
No. The Running Christmas Calendar is completely free – no subscription, no ads, no sign-up.
Who is the calendar for?
For runners aged 18+ – from beginners to regular runners with running experience. Every session shows its intensity from 1 to 5.
Do I need running experience?
A little base helps: if you can run easily for 20–30 minutes, you’ll do fine. Harder days can always be run more easily or swapped for a rest day.
What’s behind the doors?
A varied plan: easy runs, fartlek, intervals, running drills and technique, core and mobility sessions, plus rest days. On top: optional challenges, the training wheel, a daily quiz and, on selected days, vouchers.
Is the training safe?
The sessions are designed for healthy runners aged 18+ and do not replace medical advice. If you have pre-existing conditions or complaints, please check with a doctor first. In the dark: headlamp, reflectors and care in traffic.
What if I miss a day?
No problem. Opened doors stay open and you can catch up on sessions at any time.
How do the vouchers work?
On selected days a partner voucher is waiting behind the door. Reveal the code, copy it and redeem it in the partner’s shop – usually until 31 Dec.
What data is stored?
Your progress stays on your device. Usage analytics and crash reports only run if you explicitly agree, and can be switched off at any time.
Do I need an account or share personal data?
No. There is no sign-up, no login and no request for your name, email or location. If you delete the app, your progress is gone too.
Which devices does the app run on?
iPhone, iPad and Android devices – in English and German.
