The verified 2027 facts
The 15th Maratón de La Paz is scheduled for Sunday, March 14, 2027. The organizer lists the marathon start at 7:00 a.m., a 42.2 km route, and separate half-marathon, 10K, and 5K starts.
Primary source: the official 15th Maratón de La Paz page. The page is in Spanish; this guide summarizes only the facts needed for a training and logistics decision.
Decide whether the race fits your next 26 weeks
La Paz is not a generic flat-city marathon. The organizer describes a valley with very few flat streets, an uneven route across the eastern and western slopes, and an adventure-style event with some hydration points and volunteers rather than big-race support at every decision.
Before committing:
- Confirm that your registration and payment are accepted through an organizer-listed route.
- Review the official route, passage-time, checkpoint, and aid information.
- Decide how you will reach the marathon start and leave the Aranjuez finish.
- Confirm the medical-certificate requirement and seek appropriate professional guidance for your own health and altitude/travel questions.
- Count the weeks you can train consistently without compressing missed work.
Course-specific preparation decisions
The information gain is terrain and self-management, not a promise about one ideal pace.
- Build climbing and descending durability gradually; do not add both large volume and large hill load at once.
- Use effort as the primary pacing cue on longer slopes instead of forcing identical kilometre splits.
- Rehearse the shoes, fluids, fuel, and carried essentials you expect to use.
- Study the final 2027 map and passage times so navigation and checkpoints are not race-morning surprises. Some files linked from the current site still carry older edition labels, so do not treat them as final 2027 instructions.
- Keep easy days easy enough to absorb the added terrain work.
This is a general decision framework, not an individualized prescription. The running pace calculator can show split scenarios, but a flat-course prediction should not override the route or your training evidence.

Use the training-start-date calculator, then choose an existing plan from the marathon training hub. If the selected plan does not match the athlete you are now, choose a longer runway or a later goal.
Final verification card
The official page currently lists registration, route links, start locations, public-transport suggestions, packet collection, and participant requirements. Some linked route-support files still carry older year labels, so recheck all of them close to the event and use only the final 2027 versions.
- official entry and payment confirmation;
- final route, passage times, checkpoints, and aid points;
- marathon start and Aranjuez finish access;
- packet collection dates, hours, and documents;
- medical certificate and organizer rules; and
- race-week forecast and any organizer notices.
If the final organizer instructions differ from this page, follow the organizer.
Train for what changes you
A finish line can create structure, but the daily work has to remain believable: consistent training, recovery that protects the next session, and calm adaptation when life interrupts. Start with the athlete you are today.
