Hi @ultawtong, 

Thanks for posting and great job on your 10,000km run! I took a look at your club and see you have an event coming up. This is a great way to get members to your club.Another way to build your community is to post frequently. Engage with your community will get them to engage with you. You may also want to create a post on your other social networks to invite new members to your club. Building a club takes time; the most successful clubs started with just a handful of people and now have thousands of members. Best of luck to your club!

Hi, @Scout 

I will try my best.

Thank you very much for your support.

Hi Scout,

hey @Theerawut, 
Thanks for your post. At this time you cannot create club challenges. This idea has been posted to our ideas board: Create Club Challenges. You can add your kudos and comments to that post to show your support for this idea. 

While you cannot create a club challenge, you can create a club event:  Creating your Strava Club Event
