Here is a 2KM flat route at Bonifacio High Street in Bonifacio Global City, Taguig. Its an easy route with little to no uphill stretch. The route was measured using Wikimapia, thus, the 2KM distance is not 100% accurate.
This route is never a boring route, you have the busy BHS at the center plus a lot of joggers around the area. Another attraction would be the various sport shops in BHS such as Runnr, Mizuno, Nike and ROX among others.
Water station can never be a problem, drinks are sold at ROX. If you still have an energy left after the run, a lot of restaurants around the place for you to cool down. Happy running!
