There are three stages of labor.
The first stage can last as little as 30 minutes or as long as a day. It is during this stage that the mare positions the foal into the birthing position. First stage labor can also be delayed by the mare if she believes there are predators nearby.
Second stage is the actual birthing process and should take no more than 30 minutes from start to finish. Once this stage starts there is no going back, if the foal is not born within 30 minutes both the mare and foal are in serious trouble.
The third and final stage is the passing of the placenta. This can take a couple of hours. Any more than two and it would be wise to call a vet to remove it as a retained placenta can lead to infection.

How long a horse can stay in a trailer is relevant to the condition of the horse, if there is enough room for the horse to lay down etc. Are their stops for water and feed breaks? Also the condition of the trailer, does it have good suspension? Is their room for the horse to lay down? Is it bedded with shavings and rubber mats? Are the horses legs wrapped well? Many long haul horses will stay in the trailer for the entire trip, 48-72 hours with no ill effects in good quality trailers.
