Why this distance
The benefits.
The flagship distance
A double marathon: the hardest, most respected finish on the NAX Virtual Marathon 2027 start list.
Ultra-specific recognition
Verified ultra finishers are listed separately in the official results and receive the ultra finisher piece.
A 24-hour clock
The race window runs 24 hours a day, so night sections and early starts are entirely your call.
How to do it
Your guide to the start line.
- 01
Come in with marathon experience
This distance assumes you have already finished at least one marathon and can train 60KM+ weeks comfortably.
- 02
Train back-to-back long runs
Ultra fitness comes from consecutive long days — for example 30KM on Saturday followed by 20KM on Sunday.
- 03
Practise walking breaks
Structured run-walk intervals protect your legs and stomach far better than trying to run every step.
- 04
Plan aid and crew
Use a repeated loop with a fixed aid point, real food, spare shoes and socks, plus lights for night running.
- 05
Log every activity
Run it in one push or accumulate it across several runs inside your batch window, then submit a screenshot of each activity.
Complete it in one month
84.4KM in a month
Two marathons inside one batch window. Accumulated that is under 3KM a day — completely doable for a consistent runner. Attempted in one push it is a genuine ultra and needs ultra preparation.
2.8KM
Steady daily accumulation across 31 days
19KM
Three or four short runs a week
8–12 runs
Most finishers accumulate rather than push
20–30KM
One or two long days anchor the month
Weekly targets are guidance only, based on a 31-day batch window. Build gradually, keep most runs easy, and consult a doctor before starting any new training load.
