What the date changes in your training calendar
These are calendar anchors, not a promise that a given plan suits your current health, training history or available time.
If a start date has passed, do not compress missed weeks. Use the training start-date calculator, compare the marathon training plans, and choose the longest runway you can execute consistently.
Turn the official facts into race preparation
For this edition:
- build durable long-run consistency before adding event-specific work;
- verify surface and elevation from the final organizer map;
- practise fueling in the conditions and duration your long runs actually produce;
Do not copy pace, fueling or equipment from another runner without testing it. A useful long run records duration, effort, fuel timing, fluid, conditions and symptoms; change one variable at a time. Use the running pace calculator for scenarios and the marathon fueling planner for a rehearsal outline—not as guarantees.
Booking and race-week checks
Before paying for non-refundable travel:
- Reopen the official event page and confirm the date and entry status.
- Confirm that your chosen distance is offered on the date shown here.
- Read the current cancellation, transfer and deferral terms.
- Wait for the final participant guide before treating a start time, wave, route or cutoff as fixed.
- Check race-week weather and transport rather than relying on a historical average.
What remains unconfirmed
The current sources do not establish every race-week detail. Recheck:
- final registration terms;
- start time;
- route and elevation;
- cutoff;
- aid-station products;
If the final organizer information conflicts with this guide, follow the organiser. We timestamp verified facts so the next refresh can distinguish a changed event from an unchanged page.
Build from the runner you are now
The useful question is not “Can I force the calendar?” It is “What training can I repeat while absorbing it?” Start with current consistency, protect easy running and recovery, and add race-specific work only when it remains compatible with the following week.
