10×10 Run was first run on December, 2012. There was no precedent or advice. We just ran all 10 days at Marine Drive, Mumbai with no glamour or celebrations . 
Mumbai Runners officially organized 10×10 Run 2.0 in 2017, where 117 Runners completed the run on-ground with Bombay Running Crew. Many ran at their own locations and finished 10×10 in style. See the 10×10 Run 2.0 Experience here – http://bit.ly/10x10Run2
