42.2KM
42.2KM is the reason the sport exists. Done virtually, it asks for something more: you pace it, fuel it and finish it on your own terms, with no crowd and no aid station to lean on.

Why this distance
The benefits.
An official marathon finish
The standard every runner measures themselves against, verified and certified by NAX Marathon.
Deep aerobic fitness
A marathon block builds endurance, discipline and pacing judgement that carry into every other distance.
Your own race plan
Choose the route, the start time and your own support crew. Self-supported, fully your race.
How to do it
Your guide to the start line.
- 01
Plan sixteen to twenty weeks
Start from a base of comfortable 10KM runs and build to long runs of 30–32KM before you taper.
- 02
Run most kilometres slow
Around 80% of weekly volume should feel easy. Hard days only work when easy days are genuinely easy.
- 03
Fuel every 30–45 minutes
Take 30–60g of carbohydrate per hour plus electrolytes, rehearsed on every long run.
- 04
Set up your own aid
Run a loop past your car or home, or stash drinks along the route. You are your own water station.
- 05
Negative-split it
Run the first half slower than the second. Going out fast in humidity is the most common way runners fall apart at 32KM.
Before you enter
Warnings & safety.
- Do not attempt 42.2KM without a structured training block — undertrained marathons cause most serious incidents.
- Medical clearance is strongly recommended for first-time marathoners and runners over 40.
- Watch for heat exhaustion: cramping, confusion, chills or nausea mean stop and get help immediately.
- Do not over-drink plain water; balance fluids with electrolytes to avoid hyponatremia.
- 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).
