Marsiling -- Ang Mo Kio (MRT) run/walk expedition. This is my new planning. I will start from around 2-3pm. Unsure about the date. Should be next week. This is my plan.
1. Run from Marsiling to Yishun.
2. Rest at Northpoint, consume energy gel.
3. Yishun walk to Khatib to digest the water and energy gel, and also to rest.
4. Run from Khatib to Yio Chu Kang (Arduous obstacle). There are no infrastructures to block out sunlight or winds. Huge exposure.
5. Walk or run to Ang Mokio, depending on my energy and stamina level.

Total distance: I dont know. Should be at least 20Km.
