“Who can forget an event where you got your much expected PB and that too sub-2 HM with the help of two of the best Pacers in business, Shri Krishnan and Keerthana Swaminathan. I will never forget this event. Another reason to remember is the cause: Cerebral Palcy kids. I have experienced it first hand and knows how much help they need. Looking forward to the next edition. ”

“It was my train travel to Chennai with a book in hand, it was my Acclimatisation run the day before, it was my bib collection process thro my cousin, it was my touch and feel of the T-shirt given by UNIS team, it was my start with full of music and warm up at the event, it was my PB which stands till today, finally it was the cause for which I ran....! I cant highlight one, as I met my running friends and my inspiration Viji, the selfie I took with Ranish and Viji and and and and... the healthy, tasteful, and feastful breakfast post run....! ”

"Had wonderful HM run at Inner Strength Half Marathon 2017 at ECR road along the coastal line and the climate was really awesome. One of the best runner friendly events I would say because till the last finisher reached the finish line, volunteers in hydration points were encouraging and supporting the runners. Looking for an upgraded version of ISHM 2019 "

"That was one brilliant event, well organised with a nice route, awesome hydration support, volunteers cheering with motivating slogans, blessed weather and team UNIS rendering a memorable experience with loads of fun n PB for most runners. Lovely to see how ISHM 2017 has shaped up. In a short span of time, the brand has reached many runners and inspired various people into running. ISHM has proved its purpose to the society in a very transparent manner and cannot be passed on as a commercial event. Very happy and proud of dear Viji n Ranish. Cheers and kudos to your team for executing n supporting a great cause with their tireless selfless efforts. Looking forward to the next edition. "
