Why this distance
The benefits.
The headline number
The longest distance on the 2027 start list — eight marathons banked inside one month, verified and ranked in its own category.
Built for accumulation
Roughly 11KM a day. Split it across daily doses, weekend blocks or long back-to-backs — every verified run adds to your total.
Dedicated recognition
Quad Ultra finishers receive the dedicated finisher piece and a place on the longest-distance ranking.
How to do it
Your guide to the start line.
- 01
Plan the whole month
Map your weekly targets before the batch opens. Around 85KM a week, or 11–12KM a day, gets you home.
- 02
Enter with an ultra base
This assumes consistent 70–90KM weeks and at least one ultra already completed. Do not start this distance from scratch.
- 03
Protect recovery ruthlessly
Two easy days after every long run, one full rest day a week, and sleep and nutrition treated as training itself.
- 04
Watch for overuse
Rotate shoes, strength train twice a week and stop early at any sharp joint or tendon pain. Stress fractures build quietly.
- 05
Submit as you go
Upload each screenshot after every run rather than saving them all for the final week.
Before you enter
Warnings & safety.
- 337.6KM in a month is an extreme training load with serious medical risk. Do not enter without an established ultra base and medical clearance.
- Accumulating very high mileage quickly is the leading cause of stress fractures, tendon injury and overtraining syndrome. Progress gradually.
- Never chase a daily target through illness, injury, fever or extreme heat — stop and recover.
- Night running requires a headlamp, reflective gear and well-lit routes; never run alone and unannounced on long efforts.
- Entries are open to participants with a delivery address in Malaysia only. Race kits, race packs and finisher packs are delivered by our appointed logistics partner across West and East Malaysia; shipping fees may apply depending on your location.
- You run unsupported: no marshals, no water stations and no medical crew. Plan your hydration and tell someone your route before you set off.
- Obey all traffic and local regulations. You are responsible for your own safety on public roads.
- Accumulated runs are allowed: submit a clear screenshot of every activity showing date, time and distance. Edited, cropped or manually entered records may be rejected at verification.
- Only runs recorded after your registration is confirmed and inside your batch window count. Submissions close 7 days after your batch ends (23:59 MYT).
