I normally run around my housing area, 5km every 2 days, weekend on Saturday do a longer one around 7km at FRIM. Sunday is rest day. If rainy weather, also rest day.
Desa Parkcity is a good place to run and I bring my dog sometimes to run together. Many routes can be explored here and it is quite safe.
Running in itself is great exercise for your heart especially but for weight burning, there needs to be intervals, occasionally try hiking, trail running or other more explosive exercises which helps increase stamina and fat burning.
However, running has it's dangers also. I have been bitten by stray dogs and cars are also very dangerous. Wear not only proper shoes but have proper safety gear (ie reflective or bright clothing and pepper spray). Always be aware of your surroundings when you run and do not take risks.
If anyone interested to start a running group, do count me in.
