My winter lay off was October/November. December was 60 hours on the bike. I was knee deep in base training at the time which is basically what I'm in right now after a June transition month.

I'll add that "test" is kinda a loose word. I didn't really "push" either of those climbs to the max with the intent of seeing what I could do. They were just parts of overall training rides that I had a quick way to compare my before/after when I read the thread.
