About this route
Ask any Singapore roadie where they train and Mandai comes up first. The loop climbs quiet, forest-lined Old Upper Thomson Road past Thomson Nature Park, then swings west along Mandai Road, where a rise over the SLE opens up a lookout across Upper Seletar Reservoir, the classic mid-ride photo stop.
This is a road route, so it suits confident riders comfortable holding a line in light traffic. Gradients are honest by Singapore standards: nothing long, but repeated rollers that add up. Ride it at dawn for cool air, thin traffic and the best chance of hearing the forest before the road wakes up.

- Pair it with a Seletar Airport loop or the Kranji countryside for a bigger day out, since most training groups do.

Open Route in Google Maps needs nothing extra. It opens the Maps app (or website) with the whole route already plotted as pins, ready to cycle. The GPX download is useful if you navigate with an app like Komoot or Strava, or a Garmin/Wahoo bike computer. On longer routes Google may smooth a corner or two, since it draws its own path between the pins; the map below shows our fuller route line.
