Was this really a cramp or was it leg pain? A cramp is when muscles on both sides of the limb contract at the same time. Usually, you be in extreme pain and unable to move. It is not the sort of thing I would expect while biking. Cramping would be a sign of an electrolyte inbalance or dehydration. I don't think there is any magic cure for cramps in any sport.
Muscle pain in the legs on a long ride would be more expected. Acute intense pain indicates something is going on. Have you done many 50 mile rides? I would try to change body positions regularly during the ride. Use different hand positions periodically; move back and forth on the saddle, etc. I would make sure your seat height is properly adjusted (too low could really hurt after a while). I would look at the seat angle too and try to adjust that (sloping down to the front would put extra pressure on the legs I think), and/or consider replacing or changing the seat itself.
