I ran part of this route (though I’m not really sure if it’s Daang Hari, I just followed instructions given by DATC and JunC) yesterday morning. I was only able to reach until the Portofino area since I already had to go back to avoid being late for work 😀
Daang Hari seems to be a very long road… making it an ideal route where to do those long runs. It’s mostly flat and well-paved. If you run early in the morning, you’ll be shielded from the rising sun’s rays by the tall talahibs that line some parts of the road, by the high walls of Ayala Alabang and other subdivisions, and by trees in some areas.
The downside though is that there are a lot of vehicles passing through this road, so you get to suck in some of their fumes when you breathe. The presence of trees hopefully minimizes this though. There are also no sidewalks in some areas, forcing you to run on the road making it a little bit more dangerous. Also, there aren’t any houses near the road so there aren’t places to ask for help when needed.
Daang Hari generally seems to be a nice route to run on. However, I don’t recommend running it when it gets dark, due to the reasons stated above. Hopefully, I’ll get the chance to run it again, maybe going farther and seeing where the road leads to 😀
