After my first century I felt very simular for the day off and day after. I knew that I would need to take the next day off and I did. The day after the century I went home, consumed carbs and protien, and laid in bed and watched movies the rest of the night (after a shower)...

The next morning I did a recovery ride (about 20 minutes, low pressure, high cadence) and relaxed most of the day. That night I went for a nice 25 mile spin and felt good.

It gets easier for sure. My bigest ride now is 152 miles, but I have no more substantial recovery needs from a medium intensity century as a hard LT interval session, I am fine the next day.

(I would not do 2 centuries in a row... just yet)
