Challenge award expiration?

Just wondering if there was an established window of time to use your store credit with Finger Lakes Running Company. I still haven’t used the 2022 credits much less those from 2023. I’m sure we can’t expect Ian to keep track of this stuff indefinitely, but if there is an expiration it would be useful to know.

Let’s ask @Ian—my guess is that his system tracks things for quite some time, but I don’t know for sure.
