Deputy club captain Rob Conder was stoked with the local turnout.
"It went really well. Had a whole lot of new people who came along. People really seemed to enjoy it.
"People enjoy logging their times and see how other people have gone. Quite a few people do it twice or more because they want to beat their time or beat someone else's time.
"It just keeps growing. I know one lot of Harrier members, their neighbours ended up coming down. Their whole family came down and did a few laps."
Challenge two on Saturday, September 11, takes place at Springvale Park, with a 1km course being marked for competitors.
Runners have until Wednesday evening to complete their run and enter their results.
Velo Ronny's Bicycle Store is right behind the series, giving a few spot prizes to competitors.
Conder said it was great to see some familiar faces once again and he was excited to have proper catch-up once Whanganui was back in alert level 1.
"The one thing we do miss with the club is the afternoon teas, when you get to sit around and have a chat. The social side of the club."
The Whanganui Harrier Club hosts its club championships next Saturday.
