Much anticipated Nike We Run KL 10K 2012 race. I saw this photo being shared. Not sure how accurate the information. As we can see below, the date falls on 13 October 2012, 5:30pm which is Saturday evening. Start Jln Ampang. End Dataran Merdeka.
Logistic will be a headache for runners. Anyway, for me, i would park my car at nearby Dataran Merdeka, perhaps Bukit Aman Car Park, then walk to nearest Putra LRT station take LRT to Jln Ampang. .
Another cheaper option would be by bus! Car still park at BA Car Park, walk to Masjis India and take any bus which show "jln Ampang" sign. From Jln Leboh Ampang, the bus will travel along the road and into Jln Ampang.
Hope my suggestion able give some hints, idea on logistic for the Nike We Run KL.
