TTS stands for Tuesday, Thursday, and Saturday/Sunday. TTS originates YMCA runners club in Canberra, Australia. This running group is for anybody who wants to spend healthy life, and likes to jog and chat. It's easier to keep exercise with others who have the similar purpose. The area covers around Kunitachi and Tachikawa in Tokyo, though location can be also variable by participants' suggestions. Running along Tamagawa-josui, or Tama River is refreshing. Walking is also fine, and the distance is 5km~15km. The organiser is originally from Tokyo, used to live in Canberra for three years, and was a member of TTS runners club until July 2018. Good to have language exchange, slow time by running, chatting, and having coffee.
