I initially pushed beyond my limits when I was riding and recovery was tough. Like you I was wiped out the next day. I backed off slowly worked up to rides of 25 to 35 miles. I don't know how old you are, if you are younger you can push harder, or what kind of fitness base you have. But I had to back off. Now I have no problem at all doing a 25 mile ride and having energy to spare, feel fine and ready to ride the next day. I was able to do a 37 mile ride a week ago, my longest for me ever, and ride 9 miles the next day. I've been at this since spring. I started with next to no fitness as well as being overweight. It took me five months to get to riding 25 miles.
