​HK100 Flex was launched in January 2021 as a call to everyone to continue to train / run / hike / connect wherever you are in the world during the pandemic. It was great fun and we received feedback from many participants that they would like to see Flex continuing, whether physical races come back or not. So we continued to hold a second edition of Flex in 2022 and now a third in 2023. True to its roots, the running person on the Flex medal continues to wear a mask! We hope that Flex continues to give motivation to all to stay fit and strong and continue to pursue your personal trail running goals. And with the addition of The Grand Slam in 2022, now we can all find our inner superhero!

​HK100 Flex在2021年1月舉行了第一屆虛擬比賽，為呼籲大家無論在世界上任何地方在疾情之下仍然可以繼續訓練/跑步/遠足，以及用其他方法繼續保持聯繫。 我們很喜歡舉辦Flex，亦收到很多參加者的意見希望Flex無論在有沒有實體賽的情況下仍然繼續舉辦。因此，我在2022年，我們舉辦了第二屆Flex,而現在更舉辦行第三屆。Flex的獎牌亦會繼續沿用有囗罩的公仔，因為Flex是在疾情下誕生!我們希望Flex能夠繼續推動大家保持健康和強壯，追求自己的個人越野跑目標​。加上2022年新增的大滿貫，大家都可繼續去發掘自己潛在的超級英雄！
