Could be just part of the sport. Why don't all Marathoners run ultra
marathons? They run marathons to train among other distances. Same
with other runners, why would one train at 100 yards, when they could run the
440? Maybe they just have preference to to that. It's
their body atop their Horse, so they may do as they wish. I really
think most people would agree with that. I believe that what other people
do has nothing to do with anybody else, unless it impacts them in a harmful
way.

It is not necessary to do an LD before a 50 IF
you prepare properly. Many 50 & 100 mile riders have never done an
LD. Before doing a 50, I did many (and still do) 25+ mile training
rides. They just do not require the same logistical planning as 50 mile rides
do, and I can do one every weekend. This is no put down to anyone who wants to
do LDs, but why would one want to do a sanctioned LD if they often ride that
distance in training? JMHO.
