Yes, it is a nice way to earn some extra sats doing something I would do anyways. I did over a year streak of 10k steps a day and only earned whatever I was getting daily from SMiles. I could only max out at 7,300 sats a year on SMiles and can earn double or three times that in one two week challenge.

Yep, it was a big payday. I'm excited for the next one.

I think that's automatic but to claim your 43k sats from the challenge you have to go into the challenge and click claim. That's what I missed from the first one when I won the airdrop. I saw the sats in my balance and thought that was everything I was getting but there was another 19k to claim by going into the challenge. Not bad should be 100k combined for you.
