I have been running Bangalore open 10K since 2010. It was called Sunfeast 10K then. Since 2011, it has been named TCS 10K. While major part of route has remain unaltered. every year there has been slight changes in route. In fact, 2015 route resembles 2010 closely.
In following map, I have added routes from years - 2011, 2012, 2013 and 2015 in one map. I have lost GPX data for 2010 and 2014. I will try to recreate that by hand or will need to see if I can get it from elsewhere. You may click on drawer icon on left hand top menu of map and select the years that you want to see / compare.
