With 2 of the regular routes out of bound due to the F1, we were left with only the Kim Seng/Tanglin route but there was the pcn closure somewhere along the route so was a bit stuck as to where to do a proper run without having to run around in circle.
In the end decided to just go ahead and run the Kim Seng/Tanglin route since there wasn't any option and to just run a shorter distance in the worse case scenario. True enough, just after crossing River Valley Rd, the Alexandar park connector on the left was closed. Directed the first group of runners to cross over and run on the right side of the PCN while I waited for the 2nd group.
By the time the 2nd group arrived, the 1st group had disappeared. Thinking that we will meet them as they return, we ran along the PCN which sadly again was closed off less than 200metres from the road. With no where to go and hoping to meet the returning group of runners, made the decision to run along Jervois Rd, Jervois Road is a winding gently sloping road with high class private residences on both side of the road. It was peaceful and a very nice place to run even though there was some traffic zipping up and down. At the junction of Jervois Road and Jervois Lane, I faced a small dilemma. We had still not bum into the returning runners and I was wondering where they had ran to and eager to follow but I knew the small group of runners were running out of steam. In the end, we split up with 4 of us pressing on and the other 4 turning back. Imagine my surprise when within a short distance, we reached Tanglin Rd and was able to turn back onto the other end of Alexandar PCN. Further down the road when we hit the closure, I got a bit worried about the other group and decided to hunt for them. So our small group of 4 split further with 2 going back and 2 of us turning back to Jervois Rd. But in the end couldn't find any one and had to turn back clocking 11km - more than what we were supposed to do on a typical RL TNR.
However, I am glad to discover Jervois Rd. It is a nice neighbourhood to run in and a good substitute for the closed Alexandra PCN and I shall henceforth make it a part of the RL regular run routes.
