KLSCM 2025: Complete runner’s prep – start line info, training plans & packing list

The Kuala Lumpur Standard Chartered Marathon (KLSCM) 2025 is just around the corner — and whether you’re tackling the fun 5KM or going full beast mode with the 42KM, one thing's for sure: preparation is everything.

This year, with the start line moving to Jalan Raja Laut, there's even more reason to get ahead of the game. So, whether you're stressing over which shoes to wear, debating if you should finally buy that hydration vest, or wondering if your phone battery will last the full marathon (spoiler: it might if it's an iPhone 17) — we’ve got you.

But first! Don't forget about your Race Entry Pack Collection (REPC) happening this weekend

Just bring your e-confirmation slip with QR code and your IC/passport with you to collect your KLSCM race kit on:

‍Time: 11AM - 8PM, 2 and 3 October (All categories), 10AM - 6PM, 4 October (Full Marathon and Half Marathon categories)

Now let’s break all your checklist down, runner-style.

New 2025 Start Line on Jalan Raja Laut: What runners need to know?

This year, the race kicks off on Jalan Raja Laut, offering a new vibe and slightly tweaked logistics. Cue the pre-race panic:

“Wait, where do I grab my Grab?”
“Is my hotel walking distance to the start line?”
“Will there be time for coffee AND a warm-up jog?”

Do yourself a favour and sort out your race morning game plan early:

• Check updated KLSCM road closures and arrival times.
• Practice getting there from where you’re staying.
• Plan where to meet your friends and family post-race (you’ll want the victory pics, especially if you're flexing your iPhone 17’s new camera).

Smart training for KLSCM 2025: How to avoid over- or under-preparing

You signed up full of hope and energy... then life happened. Missed runs, weird weather, and suddenly your long run felt longer than expected. Yep — training for KLSCM is a journey.

Some universal tips:

• Follow a plan that suits your race category.
• Rest days = training days. Don’t skip them.
• Run in KL-like conditions. Hot. Humid. Sticky. Repeat.
• Test everything you’ll wear or eat on race day in advance.
• Track your progress with apps on your smartwatch or phone—bonus if you’re rocking the new iPhone 17’s extended battery and fitness features.

🏃‍♂️ Race-day checklists by distance: 5KM • 10KM • 21KM • 42KM

Let’s be honest — running 5KM and 42KM are two very different beasts. Here’s a breakdown of what you’ll need, based on your race category.

You're here for the vibes, the medal, and the memories. This is your runway — own it!

• Water bottle (optional)
• Fully charged phone (for pics and tracking)

• Post-run snack stash (reward yourself!)

🟡 Optional flex: Snap a finish line selfie with the iPhone 17’s new action mode — you earned it.

10KM Game plan: Speed, strategy and must-have accessories

Fast enough to hurt, short enough to sprint. You need comfort, control, and just a little bit of caffeine.
