One Open ChallengeSingapore's Green Story · 3 of 936 km Coast to CoastNParks' Coast-to-Coast Trail opened in 2019, winding 36 km from Jurong Lake Gardens to Coney Island. Our 360 km Complete-the-Network finish line is a tribute to it — ten times over.
There’s no distance to pick — everyone joins the same single challenge. These aren’t separate categories; they’re milestones you unlock as your kilometres add up. Walk or run as far as you can in 45 days, and every marker you pass earns its own badge and finisher title.
Milestone 01 · for first-timers & walkers
36km
That’s about 0.8 km a day — the walk to the kopitiam and back. Keep it up and you’ll have crossed Singapore, coast to coast. Earn The Green Corridor Finisher.
Milestone 02 · for the rhythm-finder
150km
Around 3.3 km a day — one easy evening loop by the reservoir. This is where it stops feeling like exercise and starts feeling like yours. Earn The Island Explorer.
360km
Eight kilometres a day, every day. Clear the whole canopy, take the Round-Island Route and complete the island-wide network. Earn The C2C Ultra Finisher.

Real Stories
Voices and faces from past editions of the Singapore City in Nature Challenge.
"Joined the very first edition on a whim and surprised myself past 100 km — completely hooked. That giant Singapore-shaped medal is still the biggest one on my shelf."
"As a casual walker I never imagined I'd 'cross the island' — but one kilometre a day felt so doable. My evening loops around the reservoir quietly became the best part of my day."
"We joined as an office team for the CSR, and it turned into a daily step war on our WhatsApp group. Morale went up — and the impact report looked great in our ESG update."
A whole island, out and smiling

Fair Play
Keep it real, keep it fair. Every submission is screened by the Heymetriq™ Engine — our automated integrity system that evaluates each activity against the challenge’s performance parameters in real time and filters out anything that falls outside them. Here’s what makes an activity valid.
Anything shorter than 0.5 km doesn't count toward your cumulative total.
An activity must last 60 seconds or more to be recorded.
Pace must be plausible for walking, running or hiking. Vehicle-speed entries are rejected.
Sessions below a genuine walking pace, or long idle/paused time, may not be counted.
Your screenshot should clearly capture the activity's distance and duration (date optional).
Every activity counts once. Overlapping or duplicate uploads are automatically removed.
Uploads are auto-checked on submission; anything outside these limits is flagged as invalid and rejected. Full terms and the complete activity policy are provided at registration.
Got Questions?
Not at all — 36 km (Cross the Island) is the first finisher milestone, just ~0.8 km a day. The 150 km and 360 km tiers are optional stretch goals. Any milestone reached within the 45-day window earns its badge and title.
Absolutely. Walking and running both count, anywhere in the world, on any route you love. It's a cumulative challenge — your daily kampong walk counts as much as a tempo run.
Race packs ship in waves starting mid-October 2026, in order of registration. Register early to get your gear before flag-off on World Cities Day. Flat S$4.99 delivery within Singapore, free above S$50.
Log in to your Heyrace account and submit either way: upload a screenshot of your activity, or sync directly with Strava — whichever you prefer. Every submission is validated automatically by the Heymetriq™ Engine.
