May I go horseback riding on Chol Hamoed & may I take training classes for horseback riding on Chol Hamoed as part of the course that I am taking of which one of the training days falls on Chol Hamoed?
style="text-align: justify">Yes. It is permitted to go horseback riding on Chol Hamoed even if it is not necessary for the need of the Moed. Hence, certainly you may do so as part of a Training course which would otherwise cause you a loss if you were not to participate.
