Thrissur Triathlon 4th Edition is a triathlon event featuring three continuous and sequential endurance disciplines: swimming, cycling and running. The event starts and finishes at Conolly Cruises, Chemmampilly, Thrissur. The event offers three race categories: 48miles, Olympic and Sprint, with courses combining swimming, cycling and running across different distances.

The 48miles course covers 2.25 km of swimming, 60 km of cycling and 15 km of running, with a total distance of 77.25 km and a 6.5-hour cut-off time. The Olympic course covers 1.5 km of swimming, 40 km of cycling and 10 km of running, with a total distance of 51.5 km and a 5-hour cut-off time. The Sprint course covers 750 m of swimming, 20 km of cycling and 5 km of running, with a total distance of 25.75 km and a 3-hour cut-off time. The bike and run legs follow the same route, while the route remains open to ordinary Sunday traffic. Medical and safety personnel will be present throughout the event, and the courses are clearly marked.

The race schedule includes reporting at 5:00 AM, the 48miles flag-off at 6:00 AM, the Olympic flag-off at 6:30 AM and the Sprint flag-off at 7:30 AM. Exact flag-off times may vary slightly depending on sunrise, while the order of events remains the same. Athletes must complete the entire designated course, use mandatory helmets during the bike leg, affix the bib to the front and back of the bike, avoid drafting and handle their own technical issues during the self-supported ride. During the swim leg, athletes may use their own goggles, swim caps and tow buoys, and participants are advised not to make the event their first open-water swim. During the run leg, race numbers must remain visible and athletes may run or walk at their own pace. Manual timing will be used and e-certificates featuring recorded total time will be provided. The event also has age and gender categories for Open participants under 45 and Senior participants aged 45 and above, with separate Male and Female divisions. The minimum age is 18 years on race day, while athletes under 18 require signed guardian consent. Karuna Physiotherapy and Rehabilitation Centre is the physio partner, providing physical well-being, recovery guidance and rehabilitation support. Supporters include CCC, Teem Rider, SNP and TRIX, along with Conolly Cruises.
