Depends on what level you are and what your doing. Also breeds corospond to the riders personal needs plus physical needs.
Depends on what level you are competing at? Like if you were starting out I would maybe look at Connemara , Irish sport horses or con cross? But for the higher levels and more of TB and warmblood. I started off eventing with a Irish sports X cob pony😊
i think for most is OOTB because they already are well conditioned for the cross country and i think that's a huge help!
It really depends on what level you would like to do but generally warmbloods and TB's are suited, but it mainly depends on the individual horse, hope this helps
