Rutland or Luton

This weekend's big question (other than what the hell happened at White Hart Lane) is do I run the Rutland water or Luton Marathon. The big negative for Rutland is the start time and element of trail running. The big negative for Luton is three laps and a five hour limit. The big positive for Rutland is stunning scenery, the big positive for Luton is that my support team is able to give me drinks etc twice. I will mull it over overnight.
