Hi Vinothkumar,

Thanks for your post. At this time, we limit group challenges to 25 participants. You can read more about group challenges here.
 
However, If you are interested in hosting a global challenge on Strava, sponsored challenges are available to relevant sporting/athletic brands as a paid media activation. You can find more info here.
