It takes us just short of this time (13-14 hours) to go from home to El Reno, OK for the National Cavalry Competition. We usually break the trip at about 9-10 hours and that puts us near Ft. Smith, AR. Only once did we do the trip non-stop as we had three drivers and did it at night. It was not pleasant for the humans (at least not for me). My older mare came off a bit stiff but she worked out of it quickly. The two younger horses had no issues.
Folks can either pay attention to Newton or pay the price for not doing so.
