I continued to ride my mare up until the day before she gave birth. The last month was just a few min. Bareback in the round pen. Nothing strenuous just walking around for about 10 min. I knew I wouldn't be able to ride her for a month or so after birth so wanted to go as long as I could before the baby was born.
