back-to-back LD's.... unusual?

[Deanna German <finishis2win@columbus.rr.com>]

Angie Nathe posted about going from CTR to either LD or endurance. I
recommended doing two-day 50's instead of making the mileage jump, but then
it occured to me that back-to-back 25's might not be available in all areas
like they are here.

Are back-to-back LD's unusual? It's my opinion that this is a good "tweener"
way to ease into doing 50 miles in a day, especially for a newbie rider with
a newbie horse. I'm not talking about racing both days either; just a
completion at a pace appropriate to the conditions of the day. A multi-day
LD, if you will.

Thoughts?
