After two years of break due to social unrest and COVID-19 pandemic, Hong Kong Trail Orienteering Championships were held again in 2021, which gained World Ranking Event (WRE) status for the first time and became the final 2 World Ranking races in the year. However, as the pandemic was still widespread in the world and border quarantine still in place, it was effectively a closed-door competition to local participants only.

Chi Kin Man won the champion title having 21 correct and 18 seconds in the time controls, with Huan Kun Sy and Ronald Yeung coming a close second and third only differed by the time controls, gaining 13.46, 13.51 and 13.56 World Ranking points on a 0 (best) – 15 (beginner) scale respectively.
The TempO race was held on 19 December in Po Leung Kuk Jockey Club Tai Tong Holiday Camp. 11 elite (WRE) competitors, 6 competitors in advanced class, and 8 competitors in beginner class started the race (excluding unranked competitors due to late into quarantine).
