Rode 2 centuries in 4 days early in the month, have been lucky to get my daily 15-mile hammer in twice a week.
Recovery, for me, is about 2 days for a century, another day to think about it.
Mental recovery depends on the rest of the chaos around me.
Maybe it's the 20th century workday, but 8 hours in the saddle, and I'm thinking of other things.

No way could I run a marathon every month, and I've run about a dozen. Another reason why I like riding better.
