Thank you all for joining our HKU Walking Challenge: To the Moon! It has been a very active month for all our participants and we would like to congratulate all participants with their achievements. The HKU Walking Challenge was a platform to bring together the HKU community with the common objective of virtually walking together to the moon. We hope that you have enjoyed this challenge and being part of this great effort to improve the health and well being of its students, staff and the HKU community.
