    Our Humble Beginnings

    Some of us started biking, a few of us started running and the rest took to swimming. It was a destined day when we decided to try the other two sports and after a few years Enduro was born in Mysore. Being labelled the sleepy city, the small tribe stands out for their enthusiasm and are trying to get rest addicted to various sports. For now we are training, we are getting trained and organizing events. Tri Thonnur is our hallmark event, thanks to the gorgeous lake, brilliant food and some awesome people. We are planning a few more events for the next season, until then, train harder. We know you all love coming down to Mysore and we will make sure you visit more often.

    The 5th edition

    Enduro presents the 5th edition of Tri Thonnur, one of the few open water triathlons in India. The Tri Thonnur is conducted at the scenic Thonnur lake, 50 Km from Mysore and is nestled between withering hillocks and ancient temples. Now completing a Half Ironman is tough enough but we make it a tad bit easier for you by providing you a setting with a view, just so that you enjoy the ride.
