Along with walking and running, participants were permitted to travel via public transportation (buses, the metro and shared bicycles) to promote a healthy and low-carbon lifestyle.

"This is my first time participating in an orienteering challenge, but I have taken part in many outdoor activities in the past, like walking challenges. I think it's a really good opportunity for us to appreciate Wuxi's scenery and stay fit," said a 64-year-old participant.
