We rode 100, just as I suspected we would. My nutrition must have been a bit off today, because when I got home I immediately sat down and felt like I was too weak to even stand up. DH suspected that I was dehydrated (and I probably was) but the very thought of drinking water at that moment made me want to gag. So I just sat there, hanging my head between my knees for a while. We had a fairly stiff headwind for more than half of the ride, so I think it just wore me out...along with not drinking enough during the ride. Once I got up and moving again, I took a shower and then actually laid down for a short nap and felt a bit better afterwards. THEN I suddenly got extremely thirsty...like I simply could not get enough water in me no matter what, thirsty.
I've done many 100 mile rides, but this one (and it was a route that we've done many times, too) felt particularly tough and really kicked my @ss. Oh well, I guess we all have bad cycling days once in a awhile. Tomorrow I am planning to take it easy with a much shorter ride.
