It's extremely normal for your body to need more recovery time after a ride like that. There are some folks who wouldn't need so much, and you might become one of those people eventually, but right now your body is apparently telling you to take it easy this time around.

It's typically good to do a "recovery ride" after a strenuous ride (in your case rides, plural). My friend and I typically do a 20 mile flat and "easy" ride after a particularly long and/or grueling climbing ride. (Easy meaning we go slower pace and distance than usual). Many believe it helps your muscles recover better than doing nothing at all. Walking and other activities that get your legs moving in a not too strenuous way are also good.

Just this year I did the Solvang century with 4500 feet of climbing, which is much more than I had ever done at that time. My body took a couple of weeks before it felt strong again, while my friend felt strong within a couple of days. I still rode, but had to take it easier. A couple of months later I did the same amount of climbing as Solvang in only 43 miles and had similar recovery issues. I developed DOMS, apparently. Delayed Onset Muscle Soreness. It comes on 24 to 48 hours after you've pushed yourself way passed your usual limits (for some people). I walked down the stairs backwards for a couple of days!

However, since then, I did a century with 8500 feet of climbing (almost double what I had done before) and recovered MUCH faster ... no DOMS ... then eventually did the same climbing training ride that I had developed DOMS after before ... and two days later was able to PR a pretty strenuous club ride. (PR being my personal record).

So, in my experience, when I first push myself to new limits, my body needs a lot more recovery. When I continue to push to those same limits, my body gets used to it and recovers much more quickly. The more you ride, the more you'll know what your body can and should do after a strenuous ride. General rule would be to "plan" to take it easy if you're not sure, but if your body seems up to it, go ahead and push yourself more. Sometimes I don't know until I'm out riding if I need to take it easy or not, climb less, ride slower, let my friend pull me the whole way ... but I generally still ride.
