@uzaks, 

Thanks for reaching out. We do have a limit for the maximum number of kudos you can give per hour. Please wait an hour to try again;  if you continue having trouble, please wait 24 hours before giving more kudos. 

This is precisely why I stopped paying for Strava.

Why is there a limit?

An obvious question - what is the limit?

I counted 100 kudos before I was unable to give any more.

I have a premium account so why can't I give more kudo's.

I have around 600 people that I follow 

I pay for strava so I want more to give.

Dear Strava developers,

My kudos to my friends are deleted. I understand the need of avoiding spam-kudos, but a max of 100 is far too low. One benefit of Strava is the ability to give likes, comments, and kudos. I don’t give kudos to all, and it takes some effort to choose kudos and not kudos. Then, it’s a bad experience discovering that half of the effort is wasted, since you have deleted some of my kudos entries with no feedback or message. I hope this will be fixed soon, and before my subscription runs out. However, Strava is a wonderful app, pushing health into the public. Keep the good work!

I've started getting locked out from giving kudos well before the 100 limit mentioned here. It's important to me to encourage my friends, especially those at the beginning of their fitness journeys, please consider raising the limit.
