Waving a triumphant right fist, Muhammad Ghazzi Krisna crosses the finish line in first place, as he topped the 56km club challenge at the TRI-Factor Bike 2016 yesterday. His time of 1hr 23min 39sec beat Merrill Chua (behind) by a second. The mass cycling event saw 1,135 participants - ranging from the ages of six to 66 - riding along Nicoll Highway yesterday morning. The event is the second part of a series of four TRI-Factor events held from May to August. They each comprise one of the three disciplines (swim, cycle, run) in triathlon before culminating with a triathlon on Aug 21.
