You could do this clinic I felt the same way you did about being around 30 other people and I was very nervous. Clinton spends the first 2 days on groundwork only, to make sure we were getting the respect from our horses before he let us get on them. If he didn’t feel like our horses were ready, the academy students rode first.
I have taken riding lessons for 4 years and never felt very confident, especially when it came to cantering. It still blows my mind how in 5 days I got the confidence to canter my horse and have been cantering him with confidence ever since.
Everyone who attended the clinic was very supportive as we all faced the same demon, called Fear.
I highly recommend this clinic to anyone who has fear issues
